Answer: Global wind patterns affect how air masses move. Prevailing westerlies are the major wind belts in the continental United States. The prevailing westerlies generally push air masses from west to east. For example, continental polar masses from central Canada enter the United States between the Rocky Mountains and the Great Lakes. These cold, dry air masses are blown east and affect the weather in the central and eastern part of the United States.
The ethanol-powered gasoline which is globally supported for the environmental improvements reduces the harmful emissions and thereby reduces the gee house gas effects. About 10 % of the gasoline provides about 1% of the energy in the calorific values.
