The Impact of Orography on the African Easterly Wave Stormtrack
Joshua D. White, Anantha Aiyyer, James O. H. Russell
We examined the sensitivity of African easterly waves (AEWs) to elevated terrain over North Africa using a numerical weather prediction model. We formed five ensembles of simulated…

Acceleration of Tropical Cyclones As a Proxy For Extratropical Interactions: Synoptic-Scale Patterns and Long-Term Trends
Anantha Aiyyer, Terrell Wade
It is well known that rapid changes in tropical cyclone motion occur during interaction with extratropical waves. While the translation speed has received much attention in the pub…

African Easterly Waves in an Idealized General Circulation Model: Instability and Wavepacket Diagnostics
Joshua Dylan White, Anantha Aiyyer
We examine the group dynamic of African easterly waves (AEW) generated in a realistic, spatially non-homogeneous African easterly jet (AEJ) using an idealized general circulation m…
