Spatial Distribution of Surface Water Vapour Density over Nigeria

Authors : B. Adeyemi and E.O. Ogolo

Abstract: The spatial distributions of Surface Water Vapour Density (SWVD) over Nigeria during the decadal period 1987-1996 were investigated using daily mean temperature and relative humidity data for seven stations grouped into three areas arranged in a South-North transect; the Southern, the Midland and the Sahelian (Northern) Zones. Results show that the variations in each zone are influenced by the prevailing atmospheric conditions which are largely dependent on the seasonal North-South movement of the Inter-Tropical Discontinuity (ITD) and to some extent, by the topographical features. Values of daily mean of surface water vapour density were found to be higher at midnight than at midday at both the Southern and the Northern Zones whereas at the Midland zone, the reverse is the study.
