Abstract

The country of Bangladesh has been known to experience some of the deadliest tornado outbreaks in the world. The severe weather season in this region only spans from late March to early May, but can produce significant severe weather outbreaks in that short time. Even with these outbreaks occurring, there has not been extensive analysis completed to evaluate the environmental parameters on these tornado event days in this region.

The goal of this project is to use a Weather Research and Forecasting (WRF) model simulation to evaluate a significant tornado that occurred in the Tangail and Jamalpur districts in Bangladesh on 13 May 1996. This tornado killed an estimated 700 people and caused an additional 32,000 injuries, according to a report from Hosen and Jubayer (2016). With limited surface observations available for this event, a WRF simulation allows for a deeper understanding of the storm and further evaluation of the ingredients that lead to its development. Moisture and thermodynamic variables were evaluated to help diagnose the pre-convective environment, as well as mesoscale boundaries that led to supercell initiation.
