4. What is a Monsoon? Even in the tropics, where the weather is warm year round, the march of the seasons has a profound influence on the rhythm of life. Rainy seasons, usually referred to as monsoons , alternate with dry seasons and each has its own distinct pattern of prevailing winds. The term “monsoon” is derived from the Arabic word “mausim” which means season. Ancient traders sailing the Indian Ocean and Arabian Sea used it to describe a system of alternating winds that blow persistently from the northeast during the winter and from the opposite direction, the southwest, during the summer. It is now well understood that seasonal reversals of wind direction occur because of temperature differences between the land and sea across all of the Tropics. There are many features in common to these summer monsoon circulations, but the most recognizable are the seasonal changes in rainfall patterns, both increases and decreases.
