Abstract: The nature of African easterly waves (AEWs) and the easterly wave season over West Africa are examined using the National Centers for Environmental Prediction (NCEP) reanalysis. The study is carried out with two objectives ...

Abstract: This paper examines the mean annual cycle of rainfall and general circulation features over West Africa and central Africa for 1958?97. Rainfall is examined using a 1400-station archive compiled by the first author. Other ...

Abstract: Results are presented from a linear inverse analysis of the Southampton Oceanography Centre (SOC) air?sea flux climatology using 10 hydrographic ocean heat transport constraints distributed throughout the Atlantic and North ...

Abstract: This study examines selected dynamical factors associated with wet and dry years in the West African Sahel. The approach is to evaluate the temperature, wind, and moisture fields and the dynamic instabilities for a 4-yr?wet? ...

Abstract: Differences in the basic state over West Africa between wet and dry years are well documented. This study investigates whether there are also observable differences in the easterly waves between wet and dry years and if ...

Abstract: The influence of surface thermohaline forcing on the variability of the Atlantic meridional overturning circulation (MOC) at mid?high latitudes is investigated using output from three Intergovernmental Panel on Climate ...

Abstract: stimates of the recent mean and time varying water mass transformation rates associated with North Atlantic surface-forced overturning are presented. The estimates are derived from heat and freshwater surface fluxes and ...
