Abstract
Recent climate variability over Tanzania is evaluated through the analysis of spatial and temporal
distributions of meteorological variables including rainfall, relative humidity (RH), maximum
temperature (Tmax) and minimum temperature (Tmin) in an annual and seasonal time scale for 30 years
(1971 - 2000) at 45 meteorological stations for rainfall and 27 stations for Tmax, Tmin and RH. Statistical
parameters including mean (ME), coefficient of variation (CV) and skewness (SK) are computed and
analyzed. These parameters are mapped using Surfer software. Seasonal contribution of each of the
four seasons (JF, MAM, JJAS and OND) is assessed. It has been found that, for most of the bimodal
areas, nearly 50% of the annual rainfall is contributed by MAM season. In all four seasons, rainfall, in
most of the stations is characterized by a slight asymmetrical distribution with stronger spatial and
temporal variability. Tmax, Tmin and RH however, exhibit a near normal distribution with significantly
less variability.
