Page 1 • India’ s climate is dominated by monsoons. • Monsoons are strong, often violent winds that change direction with the season. • The term technically describes seasonal reversals of wind direction caused by temperature differences between the land and sea breeze, creating zones of high and low pressure over land in different seasons. Page 2 • India’ s climate is dominated by monsoons. • Monsoons are strong, often violent winds that change direction with the season. • The term technically describes seasonal reversals of wind direction caused by temperature differences between the land and sea breeze, creating zones of high and low pressure over land in different seasons. Monsoons occur due to changes in atmospheric pressure which are caused by different rates of heating and cooling of continents and oceans. Monsoons occur every year in many countries around the world other than South Asia - northern Australia, Africa, South America and the US are also affected. The geographical extent of the global surface monsoons (the figure below) can be outlined by the normalized seasonality Page 3 • India’ s climate is dominated by monsoons. • Monsoons are strong, often violent winds that change direction with the season. • The term technically describes seasonal reversals of wind direction caused by temperature differences between the land and sea breeze, creating zones of high and low pressure over land in different seasons.

Monsoons occur every year in many countries around the world other than South Asia - northern Australia, Africa, South America and the US are also affected. The geographical extent of the global surface monsoons (the figure below) can be outlined by the normalized seasonality The global surface monsoons contains three kinds of monsoons: the tropical, subtropical, and temperate-frigid monsoons, respectively. The extent of the classical tropical monsoons is surrounded by the positions of the Inter Tropical Convergence Zone (ITCZ) in summer and winter, which is the result of the two driving forcings of the tropical monsoon, the seasonal variation of the planetary thermal convection and the seasonal variation of the semi- permanent planetary waves due to the thermal contrast between ocean and continent.

(Li and Zeng, 2000, 2003, 2005). Surface temperature range that results in the monsoon Tibetan plateau Ocean: range of 3 to 5°C Sea surface temperature variations are much smaller than land surface temperature variations.

(Mainly the seasonal cycle) Monsoon is a term derived form the Arabic word “ Mausim”, meaning season. It was first used by Arabic navigators to describe the seasonal winds of the Arabian Sea. These winds blow from the north-east for one half of the year and from the south-west for the other half. Monsoon winds blow from cold to warm regions because cold air takes up more space than warm airRead More
