Investigation of the atmospheric circulation anomalies associated with extreme rainfall events over the Coastal West Africa

This study investigates the atmospheric circulation associated with extreme rainfall events over the coastal West Africa. The rainfall data of this study were obtained from the Global Precipitation Climatology Centre (GPCC), spanning from 1981 to 2010. The atmospheric datasets were also obtained from the ERA-Interim reanalysis. The study employed the Z-Index to categorize dry and wet years into...

active facilitation. It might also be argued that the drug was operating on consolidation processes. Since it is generally assumed that consolidation is a progressive stabilization of a memory trace over time, our data suggest that this labile phase of memory lasts for at least 5 days. That there was a trend toward facilitation in the LD(l) group supports this contention. The same trend, howeve...

Influence of atmospheric circulation patterns on dust transport during Harmattan Period in West Africa

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 ...

Oceanic Regulation of the Atmospheric Walker Circulation

A coupled theory is proposed to account for the magnitude of the Walker circulation in the tropical Pacific. It is suggested that the Pacific Walker circulation is at a saturation state, at which the zonal sea surface temperature difference is bounded by about a quarter of the latitudinal difference of the radiative–convective equilibrium sea surface temperature.
