American monsoon system
The American monsoon system is a regional expression of a monsoon on the American continents .
In North America , a monsoon phenomenon can between the Gulf of Mexico and the southern states of the United States occur. However, like all other regional monsoons, this is much less pronounced and hardly influences the ITC . A heat low in the valley of the Colorado River , the so-called Yuma Low , allows warm, humid winds from the Gulf of Mexico to penetrate deep over the continental land mass. The Bermuda high and a weak high above the quadrangle of the states of Utah , Colorado , New Mexico and Arizona also influence the monsoons. This also affects the states of Nevada and California . The summer monsoon is responsible for around 70% of the annual precipitation, usually occurs in mid-July, lasts until September and blows from the south. In contrast, a westerly wind direction dominates a winter monsoon, which results from the interaction of different pressure areas.
The starting point for the monsoon phenomenon in South America is a heating of the air layers above the Altiplano - plateau during the austral summer.
