Straight-line winds hit parts of Bara and Parsa districts of Nepal
Pokharel, Ashok Kumar
This study shows that there was a severe thunderstorm leading to an extreme straight-line wind event in some parts of Bara and Parsa districts of Nepal on 31 March 2019. It occurred due to presence of (1) an inversion layer above a lower level of deep dry adiabatic air, (2) moist air at the lower level, (3) a deep dry adiabatic layer above inversion, (4) a veering wind with height, (5) a fairly unidirectional wind from lower mid-levels into upper levels, and (6) wind speed shear at the lower level. As there was no previous history of any analysis of this kind of severe wind system (being of meteorological significance) in Nepal, this study should be quite helpful in improving the understanding of air motion and associated weather and climatic phenomena in Nepal for now and into the future.</p>
