This document discusses how various weather elements are measured, including:
- Rainfall is measured using a rain gauge in millimeters.
- Temperature is measured using a thermometer in degrees Celsius or Fahrenheit.
- Wind speed is measured using an anemometer and wind direction is measured using a wind vane.
- Air pressure is measured using a barometer.
It also mentions that students will keep a weather diary to record measurements from instruments in the school garden.
Clouds
What are clouds?
A cloud is a large collection of very tiny droplets of water or ice crystals. The droplets are so small and light that they can float in the air.
Why do clouds float?
A cloud is made up of liquid water droplets. A cloud forms when air is heated by the sun. As it rises, it slowly cools it reaches the saturation point and water condenses, forming a cloud. As long as the cloud and the air that its made of is warmer than the outside air around it, it floats!
There are 3 main types of clouds:
Cirrus or thin feathery clouds
Stratus or layered clouds
Cumulus or fluffy clouds
Cirrus Clouds
Are the most common of the
high clouds. They are composed of ice and are thin, wispy clouds blown in high winds into long streamers. Cirrus clouds are usually white and predict fair to pleasant weather. By watching the movement of cirrus clouds you can tell from which direction weather is approaching. When you see cirrus clouds, it usually indicates that a change in the weather will occur within 24 hours.
Stratus Clouds
are uniform grayish clouds that often cover the entire sky. They resemble fog that doesn't reach the ground. Light mist or drizzle sometimes falls out of these clouds.
Cumulus Clouds
are white, puffy clouds that look like pieces of floating cotton. Cumulus clouds are often called "fair-weather clouds". The base of each cloud is flat and the top of each cloud has rounded towers. When the top of the cumulus clouds resemble the head of a cauliflower, it is called cumulus congestus or towering cumulus. These clouds grow upward and they can develop into giant cumulonimbus clouds, which are thunderstorm clouds.
The Importance of Clouds
Clouds help regulate Earth's energy balance by reflecting and scattering solar radiation and by absorbing Earth's infrared energy.
Clouds are required for precipitation to occur and, hence are an essential part of the hydrologic cycle.
Clouds indicate what type of atmospheric processes are occurring (e.g., cumulus clouds indicate surface heating and atmospheric turbulence).
Clouds help redistribute extra heat from the equator toward the poles.

WEATHER is the state of the atmosphere at a given time and place with regard to temperature, air pressure, humidity, wind, cloudiness, and precipitation. The term weather is restricted to conditions over short periods of time; conditions over long periods are referred to as climate.
Belfort Instrument Company recently introduced the next evolution of Automated Surface Observing Systems (ASOS) with the DigiWx systems AWOSAV. Offering the same functionality as other ASOS, the Digi gauges weather readings including barometric pressure, precipitation, dew point, visibility, wind speed, and more, but also allows data to be transmitted via wireless connection.

In this Presentation , you can learn about the climate, weather, and the seasons of India And UK. Its a complete pack with all the custom animation , background animation and sound effects.So download it and enjoy and gain more marks in your School Projects.
Belfort Instrument Company began producing meteorological equipment in 1876; two decades later, the company’s headquarters opened as the first meteorological observatory in the United States. Today, Belfort Instrument Company produces state-of-the-art digital weather monitoring and measurement systems. The Baltimore, Maryland-headquartered business also maintains a long history of contributing to major advances in meteorological instrumentation.
GEOGRAPHY IGCSE: WEATHER MEASUREMENTS. It contains: difference between weather and climate, measuring the weather, what do we measure, temperature, precipitation, wind direction, Beaufort scale, cloud cover, air pressure, glossary.
1. Weather and Climate
Lesson 2
How do we measure the
weather?
Wednesday 18th January 2012
2. Lesson Objectives
• To know the names of weather
instruments
• To understand the units they are
measured in
• To use the instruments to record the
weather!
3. p.7 What is the difference between weather and climate?
Weather is the day to day changes in the atmosphere.
temperature precipitation
wind speed humidity
wind direction cloud cover
air pressure sunshine
4. Rainfall p.8
Rain is a type of precipitation.
Precipitation is where water vapour in the air is cooled and condenses into water
droplets.
Other types of precipitation are snow, sleet, hail, dew or fog.
How is rainfall measured?
Rainfall is measured with a rain gauge.
rain gauge
5. Temperature p.8
Temperature is how hot or cold it is.
How is temperature measured?
Temperature can be measured using a thermometer such as
the liquid-in-glass type, where the liquid (mercury or spirit)
in the bulb expands and rises up a capillary tube.
Temperature is measured in either oCelsius or oFahrenheit.
Temperatures are measured in the shade, so that the heat of
the sun does not heat up the instrument being used.
Thermometer
6. Wind p.8
Wind is simply moving air.
Wind speed is how fast the air is moving.
How is wind speed measured?
Wind speed is measured by an anemometer. This
has metal cups which rotate in the wind.
The stronger the wind, the faster the anemometer
turns.
anemometer
7. Wind direction p.8
How is wind direction measured?
Wind direction is measured using a wind vane.
In this case, the wind has come from the north.
It is a northerly wind.
the arrow points
into the wind
See if you can spot a wind vane in your local
area.
8. Beaufort scale
How is wind speed estimated without an anemometer?
The Beaufort scale measures wind intensity using the
effects of wind to estimate its speed.
It uses a scale
from 0 to 12.
0 on the scale means
there is no wind.
12 indicates
hurricane
conditions.
9. Air pressure p.8
Air pressure is the force exerted on the Earth by the
weight of the air above.
How is air pressure measured?
It is measured with a barometer (or a barograph).
12. Rainfall
Rain is a type of precipitation.
Precipitation occurs when water vapour
in the air cools and condenses into water
droplets.
How is rainfall measured?
Rainfall is measured using a rain
gauge.
Rainfall is usually measured in
millimetres (mm).
Snow, sleet, hail, dew and fog are also
types of precipitation.

14. Cloud Cover
• Your eyes are the
most useful tools to
measure the
weather
• You can look at the
sky and see how
much is covered in
cloud
• We record this in
Oktas
• 1 Okta is ⅛th
• A full sky of cloud
would be 8 Oktas
16. Weather Diary
• As a class you have to keep a weather
diary for Canbury School
• In the garden a weather station has
been set up
• Lets go outside and have a look
19. • Record what day you have to observe
the weather at Canbury
– Wednesday – EVERYONE
– Thursday –
– Friday –
– Monday –
– Tuesday –
• There is a clipboard in class to take out
and then you must fill in the class diary
