Initial Observation of a Tropical Convection Event Using VHF Active Phased Array Main Radar of Calcutta University

Troposphere-stratosphere coupling mechanisms are significantly influenced by mesoscale convective events that are linked to severe weather. When a convection event passed over the radar station, winds, turbulence and layered structures are seen using a VHF radar at the tropical to sub-tropical transition location (22.58N, 88.38E geographic) in India. Radar-observed signal-to-noise ratio cross-sections for height and time showing height and time structures of increased air turbulence linked to the convection.
