Mercosur was created in 1991 to open trade of goods and services among South American countries and promote development within the realm. The main problem has been the instability of the government during the twentieth century. 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. As this wind comes across a mountain range, it travels upwards against the slope, carrying the water vapor. Chiles expansion of business and commerce has been endorsed as a model of successful economic development to be emulated by other Latin American countries.
