Abstract

A flash-flood event affecting areas in the north-eastern Bangladesh during 16-17 April 2016 is documented. 24 hours accumulated rainfall of 100 mm was recorded over the Meghalaya region and 153 mm was recorded in the haor (wetland) region of Bangladesh, producing severe damages. Synoptic observations from the surface and upper air stations and TRMM data are used here to describe the evolution of the flash flood producing storm event. The Weather Research and Forecasting (WRF) model is set up in a nesting configuration including two domains. The simulations indicate the significant synergy of lower and upper tropospheric features which act as the triggering mechanism for the occurrence of flash flood producing rainfall event.
