GEOG 4014 Chapter : 05 Circulation
Document Summary
In the real world , air near equator rises adiabatically. After it rises, it moves toward the poles. But by the time it reaches 30 n & 30 s, the air sinks. After air sinks, near-surface circulation moves to equator. Other places are affected by the itcz and by the sths. Coriolis effect deflects winds to the right in nh and to left in sh. In the real world , the poles are so cold that there is a high pressure zone situated there. Surface wind blows away from the poles (and is deflected by coriolis effect) At 60 n and 60 s, the air rises. Polar front: the boundary between the polar cell and the. Result: surface easterlies and upper-level westerlies in these warmer mid-latitude cell . Instead of having a circulation cell, the middle latitudes have. Thus, in general, isobaric surfaces will slope from the equator to the poles as you go up in the atmosphere.
