Summary
This Geophysical Research Letters study used NASA global mesoscale simulations to examine 30-day forecasts of African easterly waves during the 2006 NAMMA period. The simulations reproduced the initiation and westward propagation of six consecutive waves and captured the mean African easterly jet with useful realism. Additional experiments showed that land-surface processes, dynamic initial conditions, and nonlinear interactions all influence predictability, with the realistic simulation of the fourth wave pointing to possible hurricane-formation lead times as long as 22 days in this case.
