Ridging South Atlantic Anticyclones contribute an important amount of precipitation over Africa. Here, we use a global coupled climate model and the ERA5 reanalysis to separate for first time ridging highs (RHs) based on whether they occur together with Rossby wave breaking (RWB) or not. We show that former type RHs are associated more than latter type. The mean sea level pressure anomalies cau...

The propagation characteristics of near-inertial waves (NIWs) and how mesoscale submesoscale processes affect the waves' vertical penetration are investigated using observations from a mooring array located in northeast Atlantic. year-long show that motions mainly generated by local wind forcing, they radiate equatorward downward following several strong events (wind stress ?0.5 N m?2). Observa...

Abstract When a fluid system is subject to strong rotation, centrifugal motion expected, i.e., denser (lighter) moves outward (inward) from (toward) the axis of rotation. Here we demonstrate, both experimentally and numerically, existence an unexpected warm lighter vortices in rotating thermal convection. This anomalous vortex occurs under rapid rotations when buoyancy sufficiently induce symme...

Past climatological research has not quantitatively defined the synoptic-scale circulation deviations responsible for anomalous summer-season precipitation totals in the southeastern United States. Therefore, the objectives of this research were to determine the synoptic-scale controls of wet and dry multiday periods during the summer within a portion of the southeastern United States as well a...
