Abstract The Intertropical Front (ITF) is a fundamental feature of the atmospheric circulation over West Africa. It separates wedge warm moist southwesterly monsoon flow off tropical Atlantic from much hotter and very dry northeasterly wind Sahara Desert. Here, daily temperature, humidity, rainfall data for 1974–2003 are analyzed to document northward advance southward retreat ITF between boreal spring autumn, assess its role in Sudan–Sahel (10°–20°N) patterns. Using largely dekadal (10 day)...
Abstract The major objective of this study is to re-evaluate the ocean–land transport moisture for rainfall in West Africa using 1979–2008 NCEP–NCAR reanalysis data. vertically integrated atmospheric water vapor flux surface–850 hPa calculated account total low-level contribution over Africa. Analysis mean monthly fluxes shows a progressive penetration into from south and west. During spring (April–June), northward forms “moisture river” transporting current Gulf Guinea coast. In peak...
An overview is presented of the meteorological and thermodynamic data obtained during Radiative Atmospheric Divergence using Radiation Measurement (ARM) Mobile Facility, Geostationary Earth Budget (GERB) data, African Monsoon Multidisciplinary Analysis (AMMA) stations (RADAGAST) experiment in Niamey, Niger, 2006. RADAGAST combined from ARM Program Facility (AMF) at Niamey airport with broadband satellite GERB instrument on Meteosat‐8. The was conducted collaboration AMMA project. focus this...
The vertically integrated surface-850 hPa atmospheric water vapor flux is investigated, to account for the total low-level moisture contribution rainfall over West Africa (WA), based on NCEP–NCAR reanalysis data. focus contributions transport and convergence by mean circulation, synoptic (<10 days), climate (>10 day) scale anomalies. For WA, time-mean flow anomalies are comparable. Similarly, meridional zonal components, transports largest contributors transport. While responsible driving...
