Now as the anti cyclonic circulation returns over western India and its wind flow returns over North and central India. Under influence of the Anti-CC, air sinks which result in development of a high pressure area. this systems forms over a large geographical area. also this system causes the winds to become gentle and extremely dry, there is no rapid change in atmospheric air pressure and hot and dry weather prevails over north, central and adjoining parts of India. there is not sufficient moisture in the atmosphere to support any cloud development and this weather pattern prevails for atleast 8-10 days and sometimes even for more than 15 days
