Controls (Continued) Air cools as it flows north and south at high altitude, and it eventually descends around 30 N and S. Some air flows back to the equator at the surface, and some flows pole-ward; air flowing to the equator completes circulations called the Hadley Cells. The Coriolis Effect causes winds (or anything else that moves) to appear to bend to the right (with respect to its direction of motion) in the northern hemisphere, and to appear to bend to the left in the southern hemisphere.

Other Important Factors Mountains force air up, create montane rain belts and rain shadows land heats up and cools down much more rapidly than does ocean and this temperature difference can drive land-sea breezes and monsoons Ocean currents are driven by the winds, and deflected by continents, and these currents influence the climate of coastal regions most of the land outside the tropics is now found in the northern hemisphere

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
