why does the tropical rain forest receive so much rainfall?

Answer 1

tropical rainforests are generally near the equator. the sun is at its most intense most of the year in these areas. water is evaporated very rapidly from ocean and sea surfaces. this warm, moist air rises into the atmosphere. the water vapor then cools as it gets higher in the atmosphere, condenses to form rain droplets and then rains from the sky when it becomes too heavy to be kept aloft.

there is so much rain because there is such a high rate of evaporation. this high rate of evaporation and high temperatures also account for the high humidity that is generally present in the rainforests (warm air can hold more moisture, thus increasing its absolute humidity potential).

hope that helps. :)

Answer 2

You may be knowing that the equatorial regions get the maximum solar radiation almost throughout the year.Because of this,the temperature over these regions are very high.As warm air can contain more moisture than cold air,moisture is abundant in the air over the tropical regions.As the equatorial belt is a low pressure area, these moist air rises due to convection and form clouds throughuot the year.These clouds give plenty of rain over this area.
Moreover,the inter-tropical convergence zone, where the tropical air masses of the both hemisphere meet ,lies near the equator.These airmassess are warm and humid and have favourable lapse rate upto great heights.Therefore convection starts on a large scale resulting in the formation of clouds(including thunder clouds) which give torrential rain.This is the reason for the existance of tropical rain forests and for the heavy rain over these forests.
