3. Account for the existence of the Sargasso Sea where the tropic goes through the North Atlantic. 4. If the earth rotated from east to west, what kind of currents would flow off the British Isles. Kamchatka, and Labrador J Rainfall. The distribution of rainfall as shown on PI can in almost every case be accounted for < by the reasons given on page 16. It must be remembered also that winds blowing from cooler to wanner regions (as the Trade winds) naturally do not drop BO much moisture as winds which become gradually cooled as they travel away from heated areas. In the equatorial regions the great updraught caused by the sun's heat causes the air currents which reach those latitudes to ascend and become cooled : hence the rainy belt round the equator. The name of " Convectional Rains" is often given to the equatorial downpours, and " Cyclonic Rains " to those caused by the low-pressure storm areas, so commonly found along the coa.- - temperate regions, especially in winter.
