The Sensitivity of WRF Daily Summertime Simulations over West Africa to Alternative Parameterizations. Part I: African Wave Circulation

Autor: Erik Noble, Matthew Fulakeza, Leonard M. Druyan

Publikováno v: Monthly Weather Review. 142:1588-1608

The performance of the NCAR Weather Research and Forecasting Model (WRF) as a West African regional-atmospheric model is evaluated. The study tests the sensitivity of WRF-simulated vorticity maxima associated with African easterly waves to 64 combina

Propagation of Convective Complexes Observed by TRMM in the Eastern Tropical Atlantic

Autor: Matthew Fulakeza, Leonard M. Druyan

Publikováno v: The Open Atmospheric Science Journal. 6:1-8

Precipitation maxima during the West African summer monsoon propagate generally westward in tandem with African easterly waves. A heretofore unreported, repeating pattern of northward drift of precipitation maxima is detected on Tropical Rainfall Mea
