  • Places facing the sun will be warmer than those in the shadow
  • Weather & climate project by Matthew Ben Hamed 3.02

    1. 1. Weather & Climate Geography project April 2012 Matthew Ben Hamed 3.2
    2. 2. Observing & Recording the Weather• Weather is the condition of the air around us over a short period of time ex. Rainy or cloudy.• Meteorology is the study of the atmospheric conditions & air circulation.  A meteorologist is a person who studies the weather & works at the meteorological (met) office.  The met station is the place where they forecast the weather. There are a number of instruments which help in the forecast of the weather.
    3. 3. Weather & MeasurementsDescription of weather Measurements used1. Temperature - how hot or 1. Thermometer (⁰C) cold it is.2. Precipitation - how water 2. Rain Gauge (mm) from the air falls to the ground. 3. Beaufort Scale (force)3. Wind Speed – How strong the wind is blowing.4. Wind Direction – From 4. Wind Vane where the wind is blowing
    4. 4. Weather & Measurements(cont)5. Cloud Cover - The 5. Octa (Factors of eight) amount of sky covered by clouds.6. Cloud type - this is 6. Cumulonimbus, based on the shape, cumulus, stratus & size & height of the cirrus cloud. 7. Meters7. Visibility - the distance that can be seen.8. General weather – 8.Sunny, rainy, cloudy, etc. Description in words of the weather.
    5. 5. Weather Map
    6. 6. Features affecting Temperature & Wind• Microclimate is the climate conditions of a small area which is different from the general surrounding.• What causes Microclimate? Physical features - Forest, Hills, Lakes & Seas Shelter - Walls, Trees, Hedges, Buildings Surfaces - The color of the ground surface Buildings - Provide shade from sun & shelter from wind Aspect – The direction in which a place is facing
    7. 7. Places facing the sun will be warmer than those in the shadow Hilltops are usually cool and windyWater areas such as lakes havea cooling effect and my alsoproduce light winds
    8. 8. How does it rain?The water cycle (hydrological cycle) begins byEvaporation & Evapotranspiration (waterchanges from liquid to gas). As the moist air risesit cools & water droplets form. Thencondensation occurs & cloud forms. As the waterdroplets grow larger they become too heavy &fall to the ground - precipitation which usuallyhappens in the form of rain. Then the surfacerunoff goes back to sea.
    9. 9. Types of rainfall• Frontal rainfall happens when a mass of warm air meets a mass of cooler air.• Warm air is lighter then cooler air & is forced to rise.
    10. 10. Types of rainfall(cont)• In Relief rainfall the warm moist air is forced to rise over mountains.• When the air rises, it cools, condensate & rain falls.
    11. 11. Types of rainfall(cont)• In Convectional rainfall the sun warms up the ground, which warms up the air above it.• The warm air rises, it cools, condensates & rain falls.
    12. 12. Anticyclones• Anticyclones are high pressure weather system, which usually gives good weather.• The air sinks, clouds do not form and therefore no rain occurs.• In summer, anticyclones bring hot and sunny weather, whilst in winter they bring clear skies, low temperatures with a risk of fog or frost.
    13. 13. Depressions• Depressions are low pressure weather systems that produce cloudy and rainy weather.• Depressions develop when warm air meets cold air and bring a sequence of weather changes as they pass overhead.• Due to the rising of air caused by the movement of the fronts and interaction between the warm and cold air there are lots of clouds and precipitation.
