Major Impacts On Precipitation By Latitude
The region in which the equatorward moving surface flows converge and rise is known as the intertropical convergence zone, or ITCZ, a high-precipitation band of thunderstorms.
Having lost most of its water vapor to condensation and rain in the upward branch of the circulation, the descending air is dry. Low relative humidities are produced as the air is adiabatically warmed due to compression as it descends into a region of higher pressure. The subtropics are relatively free of the convection, or thunderstorms, that are common in the equatorial belt of rising motion. Many of the world's deserts are located in these subtropical latitudes.

Famous quotes containing the words major and/or impacts:
“No culture on earth outside of mid-century suburban America has ever deployed one woman per child without simultaneously assigning her such major productive activities as weaving, farming, gathering, temple maintenance, and tent-building. The reason is that full-time, one-on-one child-raising is not good for women or children.”
—Barbara Ehrenreich (b. 1941)
“We are no longer in a state of growth; we are in a state of excess. We are living in a society of excrescence.... The boil is growing out of control, recklessly at cross purposes with itself, its impacts multiplying as the causes disintegrate.”
—Jean Baudrillard (b. 1929)
