5th Grade Weather Review

This document provides an overview of weather and climate concepts for 5th grade students. It defines weather as the daily conditions of a specific place, while climate is the average weather conditions over a long period of time, such as 10 years. The document then covers various weather phenomena like severe weather events, cloud types, heat transfer mechanisms, the water cycle, jet streams, and the reasons for seasons. Meteorologists use tools like barometers, rain gauges, anemometers and thermometers to collect weather data.

WEATHER Weather is the day-to-day conditionsofa specific place. Forexample:Itwassnowingtodayatschool.Yesterday,it wassunnyathome. WHAT IS WEATHER YOU ASK? © 2014, A. Bailey
CLIMATE Climate and weather are NOT the same! Climate is the average weather of a region over a long period of time. Climatologists collect weather data every day in a specific region inorder to officially establish a specific climate for a place or season. Most climatologists need atleast 10 years to determine a region’s climate. © 2014, A. Bailey

WEATHER INSTRUMENTS Air pressureis the weight of the air that pushes down on earth. A barometeris a weather tool used to measure air pressure. BAROMETER © 2014, A. Bailey
WEATHER INSTRUMENTS Barometers can help us predict the weather! Low pressureusually meansit will becloudy, rainy, or windy. High-pressureareas usually create cool, dry air andclear skies. BAROMETER © 2014, A. Bailey
WEATHER INSTRUMENTS RAIN GAUGE A rain gauge is an instrument used to measure the amount of precipitation in a certain amount of time and in a specific area. © 2014, A. Bailey
WEATHER INSTRUMENTS ANEMOMETER Wind Speed is how fast or slow the wind blows! An anemometer is an instrument used to measure wind speed, which is how fast or slow the wind is blowing. © 2014, A. Bailey

WEATHER INSTRUMENTS HYGROMETER A hygrometer is an instrumentused to measure the amount of humidityor water vapor in theair. © 2014, A. Bailey
ATMOSPHERE The atmosphere is a thinlayer of mixed gases that covers the Earth. It also makes up the airwe breathe. And helps the Earth from becoming too hot or too cold. © 2014, A. Bailey
WEATHER-AIRPRESSURE  Low pressurehappenswhen the air pressureis lower than nearby areas.  Whenthe air gets warm, it expands and rises.  Ina low pressuresystem, expect wet weather andwarmer temperatures.  A low pressuresystem is represented as a big, red L on weathermaps. LOW PRESSURE AREA © 2014, A. Bailey
WEATHER-AIRPRESSURE  High pressure occurs whentheair pressure inanarea is greater thanthe airpressure in surrounding areas.  In ahigh pressure system, expect sunny,dryweather, andcooler temperatures .(Think…fair weather andlightwinds)  Because thetemperaturesare cooler in high pressureareas,air sinks. HIGH PRESSURE AREA © 2014, A. Bailey
WEATHER-AIRMASS  Air massesare largebodies of air (“blocks” of air) that movethough the atmosphere and havethe same temperature, moisture, and pressure.  Theyare responsible for most of the weather that we experience. AIRMASS © 2014, A. Bailey
WEATHERFRONTS  Frontsare boundaries that separate warm air masses from cold air masses.  They canextend in both vertical and horizontal directions.  There are two basic types of fronts: Cold Front & Warm Front. FRONTS © 2014, A. Bailey
COLD FRONT Cold fronts usuallymove from northwest to southeast. © 2014, A. Bailey
 A warm front pushes the cold air massout and brings in warm,moist air.  Warm fronts usually move from southwest to northeast. WARM FRONT WarmFrontSymbol © 2014, A. Bailey
It all begins with the sun! The sun is the reason why we experience different kinds of weather on earth. Since this energy from the sun heats up the Earth's surface and atmosphere, some of it is or becomes heat energy. Conduction, convection, and radiation are the three ways heat is transferred into the atmosphere. HEAT TRANSFER © 2014, A. Bailey
HEAT TRANSFER CONDUCTIONOUCH!! This handle is hot! Conductionis thetransfer ofheat energy between thingsthataredirectly touching.Conductioncan happenwithinone object. Forexample,when youare cooking,heatenergy can be conductedthroughthe handleofa metalpot. © 2014, A. Bailey
Why would picking upa cup of hot chocolate be an exampleof conduction? • Thehot chocolate is in direct contact with the cup. • When thecupis pickedup, it will bein direct contact with your hand. • Heat is transferred through objects that are touching. HEAT TRANSFER CONDUCTION © 2014, A. Bailey
HEAT TRANSFER CONVECTION Convection is the movement of heat energy by the movement of liquids or gases. Convection in oceans and the atmosphere helps todistribute heat energy around Earth and is an important factor influencingweather and climate. Because the Sunhits Earth’s surface and warms the air nearthe ground,the warm, less dense air is moved upwards . As a result, clouds are formed. Clouds Form Sun heats the ground. Warm air rises © 2014, A. Bailey
HEAT TRANSFER CONVECTION Whywoulda hot airballoonrising be an exampleof convection? • Remember,convection isthe movementof gasesand liquids caused by heattransfer. • Airisa mixtureof gases,and as gasesareheated, theywarm, expand, and rise. © 2014, A. Bailey
HEAT TRANSFER RADIATION Radiationis thetransfer ofenergy by electromagnetic waves. Electromagneticwavescantransport energy throughplaceswithor without anymatter.The Sunis themainsource ofelectromagnetic energy on Earth. Radiationcanalsohappenin other situationssuch asstandingin frontofa fireplace. Thething toremember is radiationis not"felt" untilit is absorbed by asubstance. © 2014, A. Bailey
Why wouldheatingupyourleft over lunch in a microwaveoven bean example of radiation? • The transferofelectromagnetic waves occurs atadistance throughairinsidethe microwave oven. • When the electromagnetic waves come in contactwith food,waves transferheatto thefood. HEAT TRANSFER RADIATION © 2014, A. Bailey
•Clouds result from the condensation of water vapor in the air. •Nighttime clouds keepthe earth warmerand daytime clouds keep the earth cooler. •The names of clouds are Latin, and these names describe the cloud’s height from the ground and its shape. CLOUD CLOUDS © 2014, A. Bailey
CLOUDS CLOUD FORMATION Sohow are clouds formed??? •Cloudsaremadeup oftinywater dropletsorice crystals. •The airis filledwith watervapor. •Whenthe airis cooled,the watervapor condenses meaning thewatermolecules clustertogetherarounddustandother particlesin theair. •Theyformdropletsofwater. © 2014, A. Bailey
CLOUD CLOUD TYPES All clouds form in the troposphere. Themain types of clouds are: Cumulus (meaning"heap"or "pile"): puffy clouds that appear to rise up from a flat bottom. Stratus(meaning "layer"):short and spread across great distances; they form inblanket like layers. Cirrus (meaning"curl of hair"): wispy and thin; form at very high altitudes out of ice crystals and havewispy, featherlike shape. Nimbus (meaning"rain"or "rainycloud"): likely to bringprecipitation (like rainor snow). © 2014, A. Bailey
Cumulusclouds arethe largecloudsthatsometimes looklike huge cottonballs. Sometimes,thesecloudsalsolooklike animalsor familiarthings. Smallcumulus clouds thatarespreadacrossthesky indicategood weather,butif theyget bigger, theymay producerainorsnowshowers. CLOUD TYPES CUMULUS © 2014, A. Bailey
CLOUD TYPES CUMULUS © 2014, A. Bailey
When cumulus clouds grow taller, getdark gray, and rain or hail falls from them they are then called cumulonimbus clouds. These clouds often produce lightning and thunder (thunderstorms). CLOUD TYPES CUMULONIMBUS © 2014, A. Bailey
CLOUD TYPES CUMULONIMBUS © 2014, A. Bailey

Bailey
CLOUD TYPES STRATUS © 2014, A. Bailey
CLOUD TYPES FOG A cloud that touches the ground is called fog. Fog forms when a nearby area is moist and cool enough for condensation to happen. Fog can beboth thin and very dense. Densefog can bevery dangerous becauseit makes seeing difficult. © 2014, A. Bailey
CLOUD TYPES FOG © 2014, A. Bailey
WATER CYCLE Each step in the water cycleinfluences weather becauseit controls the distribution ofwater on Earth and in the atmosphere. This is most evident in the form of clouds andprecipitation because they are evidence of water moving through the water cycle. © 2014, A. Bailey
WATER CYCLE Duringevaporation, heatfromtheSun causeswateron Earth (oceans, lakes,ponds, etc)toturnfromliquid intoagas called water vapor andriseintothe sky. 1.EVAPORATION 2.CONDENSATION During condensation, water vaporin the airgets cold andchanges back into liquid and forms clouds. You can also seecondensationtakingplaceona hot day.Poura glassof cold andnotice how waterforms ontheoutsideof the glass. Thedropletsactuallycame from the airbecausewater vaporin the warm air,turnsback intoa liquidwhenit touchesthe cold glass. 3.PRECIPITATION Precipitationhappens when clouds getfull andheavyand water falls backtotheEarthin theformofrain,hail,sleet orsnow.Precipitation directlyinfluences a regionsclimatebecause theaverageprecipitation tellsusiftheregionwill bewetordry. © 2014, A. Bailey
WATER CYCLE Run-off happens after precipitation. Thiswater that has fallen back to the groundeither soaks into the soil or makes itway back into another body of water suchas a puddle, ocean, lake, etc. © 2014, A. Bailey
JET STREAMS Jet streamsare powerful windsthat travel at high altitudes and can reachspeedsbetween120-250mph . They influence precipitationand temperaturesand markboundaries betweenhuge air masses. Jet streamsareimportant to themoving ofhighs and lows that affectour weatherand lives on a day by day basis.Jet streamsare found at or just belowthe top of thetroposphere. © 2014, A. Bailey
JET STREAMS Jet streamsdevelop whenair flows fromcold,high pressure regions into warm, low pressure regions. The largerthetemperature difference,thestrongerthe jet stream. © 2014, A. Bailey
JET STREAMS Thetwo jet streams that directly affect U.S. weather and transport weather systems are the polar jet stream and the subtropical jet stream. Thepolar and subtropical jets are both westerly, meaning they travel fromthe west toeast. Both jet streams move north and south with the seasons. © 2014, A. Bailey
REASONS FOR SEASONS I heardthat some parts ofthe year arewarmer because we're closer tothe Sun. Isthat true? © 2014, A. Bailey
REASONS FOR SEASONS Great question, but it’s not the distance fromthe Sun, it’s the round shape and tilt of the Earth. See, the portion of Earth that’s tilted toward the Sun receives moredirect sunlight and has summer. Thepart that’s tilted away gets only indirect sunlight and has winter. SUMMER WINTER WINTER SUMMER When one hemisphere is experiencing summer,the opposite hemisphere is experiencingwinter. © 2014, A. Bailey
Let’s take acloserlook! EARTH’SAXIS © 2014, A. Bailey
HOT medium medium COLD COLD ThemoredirectlytheSun’s rayshitEarth,themore heat they bring. Whentherayshitindirectly, theirstrength is spreadout. Thepartof Earththatistilted toward theSun receives moredirectsunlight, makingthatarea warmer.Themiddleoftheplanetgetsthe mostdirectsunlight (heat). © 2014, A. Bailey
So, the ROUNDshape and the TILT are two big reasons why we have seasons, butthere is another reason why wetilt either away ortoward the Sun at different times during the year. TheEarth REVOLVES around theSun (takes about 365 ¼ days to make a complete revolution)! Take a look at howEarth revolves around the Sun. © 2014, A. Bailey
WhenEarth orbits, it reaches Fourmain points. SummerSolstice •Summerbegins in late June. •This is when Texas is tilted toward the Sun. •Wehave the longest days and shortest nights of the year. © 2014, A. Bailey
Threemonths afterSummerSolstice… Autumnal Equinox •Autumn/Fall begins in late September. •TheTexas tilt is balanced. •We have12 hour days and 12 hour nights. © 2014, A. Bailey
Three months after Autumnal Equinox… WinterSolstice •Winter begins in late December. •This is when Texas is tilted away from the Sun. •Wehave the shortest days and longest nights of the year. © 2014, A. Bailey
Threemonths afterWinter Solstice… VernalEquinox •Spring begins in late March. •TheTexas tilt is balanced again. •We have12 hour days and 12 hour nights. © 2014, A. Bailey
Now, I knowwhywe haveseason on Earth! • First, roundplanets heat up whenthey get direct sunlight and are colder at the poles (top an bottom). • Second, the Earth’s axis is TILTED23.5degrees. • Lastly, as Earth revolves around the Sun, thetilt causes different parts of it to get moreor less sunlight for a few months, causing the weather and daylight to change. © 2014, A. Bailey
WINDSAFFECT WEATHER Windsarenamedbasedonwherethey comefrom,meaning thenametells us thedirection inwhichthey travel. Thedirectionsofthe windtellsuswhat typeofweathertoexpect. Forexample,winds fromthe Northbring cooler weather, and windsfromthe Southbring warmer weather. © 2014, A. Bailey
WINDSAFFECT WEATHER A global windis themovementof air across big distances. Thesewindsflow high in Earth’s atmosphere. Theirpatternsare predictable becausetheydon’tchangevery often. Global windsarecreated between the equator and thepoles asaresult ofair moving acrossthe globeto distributethe heatfromthe Sunmoreevenly. GLOBAL WINDS Thefigurebelow shows the movementof global winds at different latitudes. © 2014, A. Bailey
WINDSAFFECT WEATHER As you can see in the figure, the direction ofthe winds change with latitude because of the rotation of the Earth. In themiddle latitudes, where the U.S.is located, the prevailing (main) winds move from west to east (Hint…think about the word WE). GLOBAL WINDS Thefigurebelow shows the movementof global winds at different latitudes. © 2014, A. Bailey
WINDSAFFECT WEATHER Prevailing winds are also knownas Prevailing Westerlies, and they affect ourweather because they move weather systemsfrom west to east and they determine the movement offronts. Fronts help us predict weather. GLOBAL WINDS Thefigurebelow shows the movementof global winds at different latitudes. © 2014, A. Bailey
WINDSAFFECT WEATHER Local winds moveacrosssmaller distances than global winds and. move closer to the surfaceofEarth These winds areless predictable becausethey react to changesin air pressure. Local winds also change becauseofgeographical featuresas mountains, valleys, and bodies of water. LOCAL WINDS © 2014, A. Bailey
WINDSAFFECT WEATHER Local winds change when land meets large bodies of water. It’s important to understand that water takes a long time to heat and cool, while land heats and cools quickly. Thegreater the difference in the rates of heating and cooling between land and water, the stronger the winds (Remember:when warmand cool air masses collide, wind is created). LOCAL WINDS © 2014, A. Bailey
WINDSAFFECT WEATHER A sea breeze is whenair flows from the sea to the land. Duringthe day,the land is heated up faster by the Sun, causing the air over land to become warmerthan the air over water. As a result, warm air rises over the land and air over water sinks (air is moving from high to low pressure, causing winds) Sea breezes are why beaches arenormally extremelywindy! LOCAL WINDS Examine How A Sea Breeze Works Air is flowing from the sea to land© 2014, A. Bailey
WINDSAFFECT WEATHER A land breeze is the reverse of a sea breezebecause wind moves from the land tothe sea. At night, land cools quickerthanwater, and the air over the land is now cooler than the air over water. Remember,cooler airis more dense and begins to sink (high pressure) while the warmerair over the water begins to rise (low pressure).

    WEATHER-AIRPRESSURE  Low pressurehappenswhenthe air pressureis lower than nearby areas.  Whenthe air gets warm, it expands and rises.  Ina low pressuresystem, expect wet weather andwarmer temperatures.  A low pressuresystem is represented as a big, red L on weathermaps. LOW PRESSURE AREA © 2014, A. Bailey

  • 25.
    It all beginswith the sun! The sun is the reason why we experience different kinds of weather on earth. Since this energy from the sun heats up the Earth's surface and atmosphere, some of it is or becomes heat energy. Conduction, convection, and radiation are the three ways heat is transferred into the atmosphere. HEAT TRANSFER © 2014, A. Bailey
  • 26.
    HEAT TRANSFER CONDUCTIONOUCH!! This handle ishot! Conductionis thetransfer ofheat energy between thingsthataredirectly touching.Conductioncan happenwithinone object. Forexample,when youare cooking,heatenergy can be conductedthroughthe handleofa metalpot. © 2014, A. Bailey
  • 27.
    Why would pickingupa cup of hot chocolate be an exampleof conduction? • Thehot chocolate is in direct contact with the cup. • When thecupis pickedup, it will bein direct contact with your hand. • Heat is transferred through objects that are touching. HEAT TRANSFER CONDUCTION © 2014, A. Bailey
  • 28.
    HEAT TRANSFER CONVECTION Convection isthe movement of heat energy by the movement of liquids or gases. Convection in oceans and the atmosphere helps todistribute heat energy around Earth and is an important factor influencingweather and climate. Because the Sunhits Earth’s surface and warms the air nearthe ground,the warm, less dense air is moved upwards . As a result, clouds are formed. Clouds Form Sun heats the ground. Warm air rises © 2014, A. Bailey
  • 29.
    HEAT TRANSFER CONVECTION Whywoulda hotairballoonrising be an exampleof convection? • Remember,convection isthe movementof gasesand liquids caused by heattransfer. • Airisa mixtureof gases,and as gasesareheated, theywarm, expand, and rise. © 2014, A. Bailey
  • 30.
    HEAT TRANSFER RADIATION Radiationis thetransferofenergy by electromagnetic waves. Electromagneticwavescantransport energy throughplaceswithor without anymatter.The Sunis themainsource ofelectromagnetic energy on Earth. Radiationcanalsohappenin other situationssuch asstandingin frontofa fireplace. Thething toremember is radiationis not"felt" untilit is absorbed by asubstance. © 2014, A. Bailey

    Why wouldheatingupyourleft over lunchin a microwaveoven bean example of radiation? • The transferofelectromagnetic waves occurs atadistance throughairinsidethe microwave oven. • When the electromagnetic waves come in contactwith food,waves transferheatto thefood. HEAT TRANSFER RADIATION © 2014, A. Bailey
  • 32.
    •Clouds result fromthe condensation of water vapor in the air. •Nighttime clouds keepthe earth warmerand daytime clouds keep the earth cooler. •The names of clouds are Latin, and these names describe the cloud’s height from the ground and its shape. CLOUD CLOUDS © 2014, A. Bailey
  • 33.
    CLOUDS CLOUD FORMATION Sohow areclouds formed??? •Cloudsaremadeup oftinywater dropletsorice crystals. •The airis filledwith watervapor. •Whenthe airis cooled,the watervapor condenses meaning thewatermolecules clustertogetherarounddustandother particlesin theair. •Theyformdropletsofwater. © 2014, A. Bailey
  • 34.
    CLOUD CLOUD TYPES All cloudsform in the troposphere. Themain types of clouds are: Cumulus (meaning"heap"or "pile"): puffy clouds that appear to rise up from a flat bottom. Stratus(meaning "layer"):short and spread across great distances; they form inblanket like layers. Cirrus (meaning"curl of hair"): wispy and thin; form at very high altitudes out of ice crystals and havewispy, featherlike shape. Nimbus (meaning"rain"or "rainycloud"): likely to bringprecipitation (like rainor snow). © 2014, A. Bailey

  • 36.
  • 37.
    When cumulus cloudsgrow taller, getdark gray, and rain or hail falls from them they are then called cumulonimbus clouds. These clouds often produce lightning and thunder (thunderstorms). CLOUD TYPES CUMULONIMBUS © 2014, A. Bailey

Bailey
  • 42.
  • 43.
    CLOUD TYPES FOG A cloudthat touches the ground is called fog. Fog forms when a nearby area is moist and cool enough for condensation to happen. Fog can beboth thin and very dense. Densefog can bevery dangerous becauseit makes seeing difficult. © 2014, A. Bailey
  • 44.
  • 45.
    WATER CYCLE Each stepin the water cycleinfluences weather becauseit controls the distribution ofwater on Earth and in the atmosphere. This is most evident in the form of clouds andprecipitation because they are evidence of water moving through the water cycle. © 2014, A. Bailey
  • 46.
    WATER CYCLE Duringevaporation, heatfromtheSun causeswateron Earth (oceans,lakes,ponds, etc)toturnfromliquid intoagas called water vapor andriseintothe sky. 1.EVAPORATION 2.CONDENSATION During condensation, water vaporin the airgets cold andchanges back into liquid and forms clouds. You can also seecondensationtakingplaceona hot day.Poura glassof cold andnotice how waterforms ontheoutsideof the glass. Thedropletsactuallycame from the airbecausewater vaporin the warm air,turnsback intoa liquidwhenit touchesthe cold glass. 3.PRECIPITATION Precipitationhappens when clouds getfull andheavyand water falls backtotheEarthin theformofrain,hail,sleet orsnow.Precipitation directlyinfluences a regionsclimatebecause theaverageprecipitation tellsusiftheregionwill bewetordry. © 2014, A.

    JET STREAMS Jet streamsarepowerful windsthat travel at high altitudes and can reachspeedsbetween120-250mph . They influence precipitationand temperaturesand markboundaries betweenhuge air masses. Jet streamsareimportant to themoving ofhighs and lows that affectour weatherand lives on a day by day basis.Jet streamsare found at or just belowthe top of thetroposphere. © 2014, A. Bailey

    JET STREAMS Jet streamsdevelopwhenair flows fromcold,high pressure regions into warm, low pressure regions. The largerthetemperature difference,thestrongerthe jet stream. © 2014, A. Bailey
  • 50.
    JET STREAMS Thetwo jetstreams that directly affect U.S. weather and transport weather systems are the polar jet stream and the subtropical jet stream. Thepolar and subtropical jets are both westerly, meaning they travel fromthe west toeast. Both jet streams move north and south with the seasons. © 2014, A. Bailey
  • 51.
    REASONS FOR SEASONS Iheardthat some parts ofthe year arewarmer because we're closer tothe Sun. Isthat true? © 2014, A. Bailey
  • 52.
    REASONS FOR SEASONS Greatquestion, but it’s not the distance fromthe Sun, it’s the round shape and tilt of the Earth. See, the portion of Earth that’s tilted toward the Sun receives moredirect sunlight and has summer. Thepart that’s tilted away gets only indirect sunlight and has winter. SUMMER WINTER WINTER SUMMER When one hemisphere is experiencing summer,the opposite hemisphere is experiencingwinter. © 2014, A. Bailey
  • 53.

    HOT medium medium COLD COLD ThemoredirectlytheSun’s rayshitEarth,themore heat they bring.Whentherayshitindirectly, theirstrength is spreadout. Thepartof Earththatistilted toward theSun receives moredirectsunlight, makingthatarea warmer.Themiddleoftheplanetgetsthe mostdirectsunlight (heat). © 2014, A. Bailey
  • 55.
    So, the ROUNDshapeand the TILT are two big reasons why we have seasons, butthere is another reason why wetilt either away ortoward the Sun at different times during the year. TheEarth REVOLVES around theSun (takes about 365 ¼ days to make a complete revolution)! Take a look at howEarth revolves around the Sun. © 2014, A. Bailey
  • 56.
    WhenEarth orbits, itreaches Fourmain points. SummerSolstice •Summerbegins in late June. •This is when Texas is tilted toward the Sun. •Wehave the longest days and shortest nights of the year. © 2014, A. Bailey

  • 60.
    Now, I knowwhywehaveseason on Earth! • First, roundplanets heat up whenthey get direct sunlight and are colder at the poles (top an bottom). • Second, the Earth’s axis is TILTED23.5degrees. • Lastly, as Earth revolves around the Sun, thetilt causes different parts of it to get moreor less sunlight for a few months, causing the weather and daylight to change. © 2014, A. Bailey

    WINDSAFFECT WEATHER As youcan see in the figure, the direction ofthe winds change with latitude because of the rotation of the Earth. In themiddle latitudes, where the U.S.is located, the prevailing (main) winds move from west to east (Hint…think about the word WE). GLOBAL WINDS Thefigurebelow shows the movementof global winds at different latitudes. © 2014, A. Bailey

    WINDSAFFECT WEATHER Local windsmoveacrosssmaller distances than global winds and. move closer to the surfaceofEarth These winds areless predictable becausethey react to changesin air pressure. Local winds also change becauseofgeographical featuresas mountains, valleys, and bodies of water. LOCAL WINDS © 2014, A. Bailey
  • 66.
    WINDSAFFECT WEATHER Local windschange when land meets large bodies of water. It’s important to understand that water takes a long time to heat and cool, while land heats and cools quickly. Thegreater the difference in the rates of heating and cooling between land and water, the stronger the winds (Remember:when warmand cool air masses collide, wind is created). LOCAL WINDS © 2014, A. Bailey
  • 67.
    WINDSAFFECT WEATHER A seabreeze is whenair flows from the sea to the land. Duringthe day,the land is heated up faster by the Sun, causing the air over land to become warmerthan the air over water. As a result, warm air rises over the land and air over water sinks (air is moving from high to low pressure, causing winds) Sea breezes are why beaches arenormally extremelywindy! LOCAL WINDS Examine How A Sea Breeze Works Air is flowing from the sea to land© 2014, A. Bailey
  • 68.
    WINDSAFFECT WEATHER A landbreeze is the reverse of a sea breezebecause wind moves from the land tothe sea. At night, land cools quickerthanwater, and the air over the land is now cooler than the air over water. Remember,cooler airis more dense and begins to sink (high pressure) while the warmerair over the water begins to rise (low pressure).
