Abstract: This paper focuses on the East African March?May ?long rains.? Particularly, it investigates the atmospheric patterns associated to the March?May rainfall anomalies, then proposes a seasonal prediction model. In a preliminary ...
Characterization of the Interannual and Intraseasonal Variability of West African Vegetation between 1982 and 2002 by Means of NOAA AVHRR NDVI Data
Publisher: American Meteorological Society
Abstract: The interannual and intraseasonal variability of West African vegetation over the period 1982?2002 is studied using the normalized difference vegetation index (NDVI) from the Advanced Very High Resolution Radiometer (AVHRR). ...
Timing and Patterns of the ENSO Signal in Africa over the Last 30 Years: Insights from Normalized Difference Vegetation Index Data
Publisher: American Meteorological Society
Abstract: more complete picture of the timing and patterns of the ENSO signal during the seasonal cycle for the whole of Africa over the three last decades is provided using the normalized difference vegetation index (NDVI). Indeed, ...
The June–September Low Cloud Cover in Western Central Africa: Mean Spatial Distribution and Diurnal Evolution, and Associated Atmospheric Dynamics
Publisher: American Meteorological Society
Abstract: AbstractWestern central Africa (WCA) was recently shown to be one of the cloudiest areas of the tropics. Analyzing an ensemble of satellite products and surface cloud observations, we show that in June?September, WCA cloud ...
