Average atmospheric pressure from June to August (top) showing the Asiatic Low (white area).

The Asiatic Low is a low-pressure trough which lies over southern Asia, during early summer. It is located roughly over India, heading over the Bay of Bengal. It is a major action centre for the Northern Hemisphere during that time of the year.[1]

It is created by more intense July sun, causing desert land areas of Northern Africa and Asia to warm rapidly.[2]

Winds round it circle counterclockwise, from May to September or October giving persistent southwest monsoon winds from over the north Indian Ocean and South China Sea, and also south-south-west or south winds over the west Pacific Ocean.[3] Its counterpart during the winter is the Siberian High.[4]
