Chp 3: Weather and climate
Gateway 1:
Aspects of climate
Factors affecting temperature of a place
Altitude
Higher altitude, lower temperature
Distance from sea
Maritime effect vs Continental effect
Cloud cover
Day and night, presence vs absence of clouds
Latitude
Higher latitude, lower temperature
Relative humidity
100% Relative humidity
, amount of water vapor in air has reached the maximum that air can hold,
fully saturated, leading to rain
Clouds
Earth's surface heated up. water evaporates and rise as water vapor, condense at dew point temperature to mass of water droplets in air
Forming Cumulonimbus clouds
Rain
Convectional rain
Relief rain
Air pressure
Force exerted on earth's surface by weight of air above it, SI unit: Millibars
Winds
Land and sea breeze
due to uneven heating
Monsoon wind formed by
Coriolis effect
and Pressure difference
Southwest monsoon, June to September
Northeast monsoon, October to February
Climate types
Equatorial climate
Monsoon climate
Cool temperate climate
Gateway 2:
