英文摘要	The wind profiling features received from recently installed stratospheric-tropospheric (ST) radar of Gauhati University (GU) (26. 2 ∘ N, 91. 75 ∘ E) are presented in the paper along with the validation process of the data by using radiosonde-derived wind parameters. The final focus of the paper is directed onto the thunderstorm-related changes in wind fields covering both vertical and composite components. Starting with the seasonal thunderstorm occurrence character over Guwahati through eight years of observations, the importance of the work on this meteorologically sensitive subtropical zone is highlighted. For identifying the process of growth of thunderstorm, the magnitudes of updrafts and downdrafts are extracted from the ST Radar-derived storm-time wind profilings. For evaluation of atmospheric system dynamics, the structure constant Cn2 is calculated through radar Bragg-scattered signals and the resultant modifications induced by the thunderstorm on this parameter are presented and brought into ambit of discussions. The paper finally identifies the storm-induced effects in the wind field-derived variabilities, for possible adaptation as inputs for a thunderstorm predictive model. © 2020, Springer Nature B.V.
