Explain why rainfall decreases from 60°N to the Tropic of cancer on the west side of a continent and increase, in the same direction on the east side.

Explanation:
This chapter provides an overview of climatology of the tropics. The tropical regions are geographically located between the parallels 23° 27' south and 23° 27' north of the equator, referred to as the Tropic of Capricorn and the Tropic of the Cancer. From a meteorological point of view, the boundaries of the tropics are sometimes taken to be the dividing lines between easterlies and westerlies and thus the region is also sometimes considered to be bound by the latitudes 30" north and south of the equator. However, such a definition, based on the most frequently occurring differences in atmospheric conditions, is only an approximate one because these phenomena are not notably confined to particular latitudes. One of the main features of tropical regions is the very high absorption of heat and its low emanation. Thus the tropical regions can be seen as a substantial reservoir of heat energy, the shortage of heat at higher latitudes being compensated for by the excess heat in the tropics. The chapter highlights rainfall, climate, and air circulation in the tropics.
