Weather. Weather is. The current state of the atmosphere...what is happening right now. Main points to remember as we learn about weather:. The sun warms the earth’s surface and therefore all the air above the surface The earth is warmed most at the equator and least at the poles.
the average motion of molecules
↑ TEMP= ↑movement of molecules= feels hot
↓ TEMP= ↓movement of molecules= feels cold
During the day, the land gets hotter faster than the water. The heated air rises, leaving behind an area of low pressure. Wind from the cooler sea blows in to take the place of that warmer air. These happen during the day!
At night the land cools off faster than the sea. Cool air sinks creating an area of high pressure. Wind blows from the land to the sea.
Horse Latitudes= 30°N and S of
equator =calm winds= worlds
Jet Streams= 10km above the
surface blow from the west to the east
Form only at high levels, therefore are made of ice crystals
descending (going down)=H pressure
ascending (going up)=L pressure

This is the symbol for a cold front
This is the weather map symbol for an occluded front
This is the weather map symbol for a stationary front
Shows cold fronts and warm fronts
