Multiple Factors affecting the African Easterly Jet and Cyclogenesis over the Tropical AtlanticPI: W. LauCo-Is: O. Reale, A. Dasilva, K.M.Kim, and E. Wilcox
This proposal will address specific scientific issues at the “weather-climate interface” with the focus on the AEJ, and its roles in transport of Saharan Air Layer (SAL) and Saharan Airborne Dust (SAD), and their impacts on the genesis of Atlantic tropical cyclone, and the regional water cycle.
To better understand the role of SAL and SAD in cyclogenesis over the tropical Atlantic, through the interaction with the African Easterly Jet, and the possible weather and climatic impacts over the Caribbean and US southeast region.
Dust concentration, optical thickness, horizontal and vertical distribution under-flying Calipso/Cloudsat to calibrate and estimate direct effects of aerosol
Wind and moisture vertical profiles across and perpendicular to AEJ axis, to locate lateral movement of AEJ, AEW, with respect to dust transport and atmospheric heating by dust, and location of ITCZ
Cloud drop size distribution, radar echo, vertical profiles of hydrometeor and dust to estimate indirect aerosol effects on cloud and rain system evolution
