Radar Characteristics Of Wind Hazards Associated With Deep Moist Convection.

Low-level horizontal wind shear is one of the most prominent accompanying phenomena in convective thunderstorms. Hazards of low-level horizontal wind shear can often be life threathening. Among other things, it poses a serious threat to aviation, especially around airports during landings and takeoffs. Horizontal wind shear can also generate vertical vorticity, which can sometimes result in the development of mesovortices and tornadoes. Weather radars at the right places can help with detecting these phenomena by using doppler radar data, thus improving warning possibilities.In our poster, we will discuss the amount of horizontal wind shear along squall lines and regions of mesocyclone within supercells and their proximity. We quantify these regions in detail in terms of horizontal wind shear in relation to the environment in which the convection developed. The environment that determined the development of convection will be studied using proximity soundings or parameters derived from the WRF model or the ERA-5 reanalysis. The main goal of the poster will be to establish the relationship between the convective environment and the radar characteristics detected and computed from the Doppler velocity data.
