A Climatology Of Indian Ocean Subtropical Anticyclone

Present study uses the nonparametric Mann Kendall trend test to analyse the temporal variations in anticyclones over the Indian Ocean. The increasing trend in the anticyclones over 1020 hPa intensity starts to organize over the Indian Ocean during summer months. The area as well as the intensity of the high pressure system further increases during autumn months and it covers the entire southern part of the domain. During winter time further intensification and expansion covers the entire band with more anticyclones. During spring the center moves to the westwards over the Indian Ocean due to this the anticyclones started to decrease over the continent and then it attains the summer positions again
