Atlantic tropical cyclone formation: Pre-genesis evolution of tropical easterly waves and impacts of the middle to upper tropospheric dry air
… dynamic and thermodynamic evolution of tropical easterly waves (TEWs) for 164 named tropical storms over the Atlantic during 1989-2010 July-October. The evolution of precipitation and the low-level convergence suggests that convection begins to organize near the center of the wave critical layer …

Future changes in extreme rainfall events and African easterly waves over West Africa
This study examines the relationship between African Easterly Waves (AEWs) and extreme rainfall events over West Africa, and investigates how climate change could alter this relationship in the future. Satellite observations, reanalysis data, and regional climate model (RCA4) simulations (forced …

Spatial pattern of African Easterly Waves and their Precipitation in Northern Africa
African Easterly Waves (AEWs) are synoptic-scale weather systems influencing Northern Africa, with distinct northern and southern tracks affected by the African Easterly Jet (AEJ), as noted in previous research. These waves are most active in the lower troposphere around 700-850 hPa. This study …

Mechanisms of Interactions between Aerosol Physics and Atmospheric Dynamics
… variability of smoke particles from the South African biomass burning is attributed by low-frequency oscillations of baroclinic instability of the region. We proposed that the impacts of Saharan Air Layer (SAL) on large-scale climate dynamics mainly occur through coupling of dust radiative …

Unraveling the Mystery of Extreme trans-Atlantic African Dust Events: Insights from Case Studies
… and consequences of other extreme trans-Atlantic African dust events. This research aims to reduce these gaps through a detailed examination of several key events between 2003 and 2022, specifically focusing on the June 2015 event—the second strongest over the tropical North Atlantic during the …
