The Southern Cone region of South America includes the countries of Uruguay, Argentina, and Chile. On the eastern, leeward side of the mountains, the elevation drops, the air warms, and the air pressure increases. Typically, descending air also gets warmer because of adiabatic compression (as with foehn winds) down the leeward side of the mountain, which increases the amount of moisture that it can absorb and creates an arid region. The warming of ocean temperatures in the western Pacific means the area becomes more favourable for rising air, cloud development and rainfall. The western part of the mountains where Chili is located is has a drier and desert climate because of the rain shadow effect. I feel like its a lifeline.

As atmospheric pressure decreases with increasing altitude, the air has expanded and adiabatically cooled to the point that the air reaches its adiabatic dew point (which is not the same as its constant pressure dew point commonly reported in weather forecasts). The average yearly precipitation in Helena is 11 inches just shy of desert. This side of a mountainous area is away from the wind. This brings thicker cloud and ultimately results in rain. This topographical interruption can cause drastic changes for ecosystems and results in the formation of deserts along with many mountain ranges. By October, temperatures drop slightly, averaging around 50 degrees Fahrenheit (10 C) and rains increase significantly (to six inches) come November.

The main regions include Chaco, Northern, Mesopotamia, Cuyo, Pampas, and Patagonia. [2] The westerlies are the prevailing winds in the middle latitudes between 30 and 60 degrees latitude, blowing predominantly from the southwest in the Northern Hemisphere and from the northwest in the Southern Hemisphere.

Once these winds travel further inland they contain less moisture and are less likely to produce rainfall (though showers and storms still frequent inland areas of NSW and summer). A rain shadow requires that there be moisture and also that winds move consistently in one direction, so that the topography offers a constant protective element.
