air masses and fronts
what is and air mass
a large body of air throughout which temperature and moisture content are similar
what does the weather symbol ct mean
a continental tropical air mass
how much more water does the gulf stream carry then all of the other rivers in the world combined (without looking at notes)
25x
what are deep currents not controlled by (without looking at notes)
wind
what happens to the warm air mass in an occluded front
the warm air get pushed out of the way by the two cold air masses
what does the weather symbol mp mean
a maritime polar air mass
what is the definition for a surface current
Horizontal, streamlike movements of water that occur at or near the surface of the ocean
what is the definition of a deep ocean current
result from differences in water density
what is the source region for cP air masses
Northern Canada
what does the weather symbol cP mean
a continental polar air mass
what direction does the gulf stream flow (without looking at notes)
north east
what causes a deep current (without looking at notes)
water density
what is a anticyclone
the rotation of air around a high pressure center in the direction opposite to earths rotation
what does the weather symbol mT mean
a maritime tropical air mass
describe what an surface current is (without looking at notes)
a surface current is a horizontal movement of ocean water that is caused by wind and that occurs at or near the oceans surface
describe what an deep ocean current is (without looking at notes)
a streamlike movement of ocean water far below the surface
what directions do the anticyclone, and cyclone move in
anticyclone moves clockwise, and a cyclone moves counter clockwise
how does a ct air mass from the deserts affect weather
it affects weather by being very dry and warm so there is no water
describe what Continental deflection is (without looking at notes)
continental deflection is when a surface current meets land and deflects off and moved in a different direction
which type of water is more dense: cold, salty water or warm, less salty water (without looking at notes)
cold salty water
