This study has used TOMS AI as well as the reanalysis dataset of thirty-four years (1979-2012) to investigate the influence of atmospheric circulation on dust transport during the Harmattan period in West Africa, using Aerosol Index (AI) data, obtained from various satellite sensors. Changes in Inter-Tropical Discontinuity (ITD), Sea Surface Temperature (SST) over the Gulf of Guinea, and North ...

In recent years, the Indian Ocean (IO) has been discovered to have a much larger impact on climate variability than previously thought. This paper reviews processes in which the IO is, or appears to be, actively involved. We begin the mathematical model with a pattern for summer monsoon winds. Three dimensional temperature and velocity fields are calculated analytically for the ocean forced by ...

Abstract The volume of Arctic sea ice is in decline but exhibits high interannual variability, which driven primarily by atmospheric circulation. Through analysis satellite-derived products and reanalysis data, we show that winter 2020/21 was characterised anomalously sea-level pressure over the central Ocean, resulted unprecedented anticyclonic winds ice. This circulation pattern drove older f...

To study the dynamical mechanism by which Arctic amplification affects extreme weather events in mid-latitude, we investigated local and remote circulation response to pan-Arctic regional thermal forcing. A comprehensive atmospheric GCM (General Circulation Model) coupled a slab mixed-layer ocean model is used for experiment. With increasing forcing configuration, mid-latitude jet tends shift e...
