Equatorial Low Pressure belt
very large body of warm, humid and rising air at the equator which supplies rain to the tropical rain forests all around the equator
Subtropical high-pressure belts
cold air masses descend causing regular patters of rising atmospheric pressure known as^
What is a Hadley cells?
looping weather patterns form a circulation system between the equator and latitude 30 N and between the equator and latitude 30 S
What is Ferrel Cells?
an air circulation pattern between latitudes of 30 N & 60 N and between latitudes 30 S & 60 S and as polar cells at the higher latitudes
Because of the Coriolis effect the prevailing wind patterns associated with these cells d o not move in a _____ out from the ______ to the N & S but are ______ by _____ ________
straight line, Equator, Bent, Earths Rotation
Earths rotation bends
Southward-flowing air to the right in the Northern Hemisphere and northward-flowing air to the left in the Southern Hemisphere, creating prevailing easterly winds that blow from E to W aka trade winds
What are jet streams?
a prevailing wind near the top of the troposphere
