چکیده انگلیسی
We have utilized the Gadanki MST Radar and Rayleigh LIDAR to understand the vertical coupling between the lower atmosphere and mesosphere through the short-period gravity waves (GWs). The short-period GWs (20â¯min-2â¯h) are noticed both in the troposphere and in the mesosphere during the deep convection. During the convection, the large vertical velocities (>5â¯m/s) and significant variations in the momentum flux (â¼3â¯m2/s2) are noticed in the troposphere and higher fluxes (â¼45â¯m2/s2) are evidenced in the mesosphere. The observations suggest the vertical coupling between the lower and middle atmosphere during convection.
