Study Notes
Weather: What, Why, and Where
- Weather encompasses atmospheric conditions at a specific time and place. This includes temperature, precipitation, humidity, wind speed and direction, and cloud cover.
Uneven Heating of the Earth
-
Earth's spherical shape causes uneven solar radiation distribution. Areas near the equator receive more direct sunlight than areas near the poles, creating temperature differences.
-
These temperature variations are fundamental to driving atmospheric circulation. Warmer air rises, while cooler air sinks, creating wind (convection).
Atmospheric Circulation and Weather Systems
-
Warm air rising and cool air sinking establish pressure systems (high and low pressure). These pressure variations result in winds.
-
Differences in temperature and pressure create unstable atmospheric conditions, leading to storms, clouds, and precipitation.
Movement of Warm Air and Weather Patterns
-
Warm air masses, heated at the equator, move towards the poles, transferring heat and maintaining a relatively stable global climate.
-
Interactions between warm and cool air masses create weather fronts, resulting in various precipitation types (rain, snow, hail). The interaction type dictates the specific weather.
-
Air mass movement is influenced by Earth's rotation (Coriolis effect) and landmasses/mountain ranges, altering weather system trajectories and intensity.
Where Does Weather Happen?
-
Weather occurs anywhere with an atmosphere. The intensity and types vary from mountain tops to valleys.
-
Local geography, elevation, and proximity to water bodies influence specific weather phenomena. Coastal areas often experience milder temperatures than inland areas due to ocean currents' moderating effect.
