Sensitivity of WRF microphysics schemes: case study of simulating a severe rainfall over Egypt

In this work, sensitivity of ten microphysics schemes of Weather Research and Forecasting model were compared to determine which is more accurate. A case study of heavy rains over the Red Sea coast of Egypt on 26th October 2016 that caused damaging floods is the subject of this study. Three coastal...

Summary:In this work, sensitivity of ten microphysics schemes of Weather Research and Forecasting model were compared to determine which is more accurate. A case study of heavy rains over the Red Sea coast of Egypt on 26th October 2016 that caused damaging floods is the subject of this study. Three coastal areas were chosen, the city of Ras Ghareb, Wadi Elgemal National park, and Elba National park. The output precipitation from the model was compared to the satellite data obtained from Tropical Rainfall Measuring Mission (TRMM). Our analysis showed that the model has the capability to simulate the rainy events spatially and produce the cloud pattern. The results showed also that the model generally tends to overestimate the precipitation for all the ten schemes compared to TRMM data.
