WebDust devils, also called whirlwinds, form as the ground becomes so hot that the air above it heats and rises. ... In low pressure regions, where air is rising, rain is common. In high pressure areas, the sinking air causes evaporation and the region is usually dry. More specific climate effects will be described in the chapter about climate. WebBetween 30 o and 60 o lie the Ferrel Cells, composed of sinking air at 30 o and rising air at 60 o (Figure 8.2.3). ... Along the equator the rising air creates a low pressure region called the doldrums, or the Intertropical Convergence Zone (ITCZ)(convergence zone because this is where the trade winds converge).

WebIt can be found between 30° N and 60° N in the Northern Hemisphere and between 30° S and 60° S in the Southern Hemisphere. Warm air rises at 60° N at the southern edge of the polar easterly cell (Fig. 3.10). Air masses cool and sink at 30° N at the northern edge of the trade wind cell. At 60° N, part of the rising air mass goes north and ... WebThis air has lost most of its moisture after producing the equatorial rains, so the sinking air is dry, resulting in arid climates near 30 o latitude in both hemispheres.

http://www.atmo.arizona.edu/students/courselinks/fall12/atmo336/lectures/sec2/hurricanes_fall12.html WebFor example, around the area of 20 degrees latitude, the air aloft is often sinking, due to the presence of the sub-tropical high—a semi-permanent high pressure system in the subtropical regions. The high pressure pushes air towards the surface. The sinking air warms and creates a temperature inversion, an extremely stable air layer in which ... WebThis sinking (and warming) air in and around the cores of subtropical highs actually works against the increase in column weight caused by upper-level convergence, serving as a "check" on the strength of the subtropical … rosemary mustard chicken
