Air Pressure and Wind:
Air Pressure Changes: from volume, the height above Earth's surface, temperature,
amount of water vapor (all cause changes in air pressure)
Wind: air that moves horizontally
Convection Cell: part of the atmosphere where air moves in a circular pattern
because of unequal heating and cooling, warm air rises and cooler air sinks
Updraft: air that rises (always warmer air)
Downdraft: air that sinks (always cooler air)
Sea Breeze: wind that blows FROM the sea towards the land (the land warms up
faster than the sea), this is why we often feel a misty breeze when on the beach
during the day
Land Breeze: wind that blows FROM the land towards the sea (the land cools down
faster than the sea), this is why we need a light jacket when walking on the beach
at night
How are land and sea breezes produced? The land and sea breezes are created because of uneven heating and cooling on the land/sea. The winds change direction between the day and night because of the changing of temperatures over land water.
Coriolis Effect: the curving on the winds on Earth (curves to the right in the Northern
Hemisphere and curves to the left in the Southern Hemisphere)
Global Winds:
Polar Easterlies: move from the poles (cold air) and from the east (towards the
west)
Prevailing Westerlies: moves from the midlatitudes and from the west (towards the
east)....IT goes WEEEEE!
Trade Winds: located at the equator (warm temperatures) and blow from the east
towards the west (remember the sailors used these winds to help them trade!)
Isobars: lines on a map that connect all places with equal air pressures (makes
pressure patterns easy to see)
