One of the most important parameters in meteorolog. is the mean wind pro fi le in the tropical cyclone boundary layer. The vertical pro fi le of wind speed and wind direction were measured during.the period of the Nisarg. cyclone from May 31st, 2020, to June 5th, 2020, using.the newly installed Phased Array Doppler Sodar system at the Center for Space and Atmospheric Science (CSAS), Sanjay g.odawat University, Kolhapur (16.74 deg.ees N, 74.37 deg.ees E; near India ' s western coast). Our analysis revealed that the maximum mean wind speed was 17 m/s on June 3, 2020, at 10:00 IST. It also shows the chang. in wind direction from southwest to southeast on June 2 and 3, 2020. Daily hig.-resolution reanalysis data in the domain, 0 - 25 deg.ees N, 65 - 110 deg.ees E, during.the period from May 31st to June 5th, 2020, revealed the variation of the atmospheric pressure of the Nisarg. cyclone from 1000 to 1008 hPa, sea surface temperature (SST) between 30 deg.ees C and 31 deg.ees C, outg.ing.long.ave radiation (OLR) between 100 and 240 Wm-2 , wind speed between 3 and 15 m/s, and low values of vertical wind shear (VWS) were observed to the north of Nisarg. track. These observations may provide more insig.ts for the study of boundary layer turbulence during.cyclonic activities. (c) 2024 The Shang.ai Typhoon Institute of China Meteorolog.cal Administration.
