Describe the temperature, air-pressure, condition of rain and winds of south-western monsoon in details.

South western monsoon seasons occur in June to mid September. It is also known as hot-wet season. The important feature of south west monsoon is sudden onset.

*Temperature: Sudden onset of south western monsoons leads to significant fall in temperature and it starts rising in September. Temperature remains less uniform throughout the rainy season. It ranges around 32-40 degree Celsius in monsoon.

*Air Pressure: High pressure and low pressure both are seen during south west monsoon. Low pressure area is Thar Desert of Rajasthan and high pressure area develops over the Indian Ocean in South.

*Conditions of Rain: South west monsoon flows from sea to land; it carries more moisture and therefore causes more rain. The Arabian Sea branch of the south west monsoon hits the western ghats of the coastal state of Kerala and making this area the first state in India to receive rain from Southwest Monsoon.

*Winds: The winds move from the South-West Ocean towards the North east plains and are called south west or monsoon winds. South west monsoon winds blow over the warm oceans and thus bear moisture bringing abundant rainfall in India.
