The objective in this investigation was to provide a better understanding of the mechanisms and physical processes responsible for climate variability over the equatorial eastern Africa, and explore potential for short-term climate prediction. Both statistical and numerical methods have been employed in this research. Application of cluster analysis yields 8 and 9 homogeneous climatic zones respectively for the variability of the annual and seasonal rainfall. Regions that are prone to drought or floods during the different phases of El Niño-Southern Oscillation (ENSO) are delineated. Positive rainfall anomalies occur in much of the region during March-May (MAM) and October-December (OND) of the ENSO(0) years and negative anomalies dominate during the following ENSO(+1) years. These rainfall patterns are useful for short-term climate monitoring over the region. The relationship between the Quasi-Biennial Oscillation (QBO) in the lower stratospheric zonal winds and the long-rains of MAM is more significant in lagged than in simultaneous, with the most distinct relationships occurring over the western parts of the region. The QBO-index explains about 36% of the seasonal rainfall variance. There is a 60/63 percent likelihood for the occurrence of above/below normal rainfall during the westerly/easterly phase of the QBO-index. The NCAR Regional Climate Model (RegCM2) simulations have demonstrated the added value of the nesting approach in improving regional climate simulations. The model reproduces the observed characteristics of the Turkana low-level jet. The study has shown the importance of orographic forcing, the large-scale background monsoon flow and depth of the channel in the development and maintenance of the jet. Thermal and frictional forcing play equivalent roles as that of the large-scale winds in the formation of the jet. The identified regions of strong winds associated with the jet are important to the safety in the aviation industry and are also pot.

This book was released on 2004. Adapting the Weather Research and Forecasting Model for the Simulation of Regional Climate in East Africa available in PDF, EPUB and Kindle. The regional climate model (RCM) is a tool to fill the gap between the outcome of global climate model and the demand of regional government and society for regional climate information. The current Weather Research and Forecasting (WRF) RCM inherits several advantages of the original WRF model. For example, (1) it can be used for multiple scale applications from large eddy to planetary scale; (2) it can be coupled to other climate system component models; (3) it has multiple physical options for different purposes of research; and (4) it has parallel infrastructure to distinguish the scientific problems from engineering problems. In order to adapt WRF for long term integration for climate application, the model and its pre- and post-processors are modified in several aspects, including SST and other surface parameters treatment, and exponential relaxation lateral boundary. In this study, we also transferred a pre-released version of CAM3 radiation scheme that was first implemented into WRF by NCAR Regional Climate Modeling team to the WRF standard release versions (2.1.1 released as of November 8, 2005 and 2.1.2 released as of January 30, 2006). The preliminary investigation demonstrates that the model has shown the encouraging and promising results on simulating regional climate. The objective of this study is to investigate the hydrological cycle in the East Africa region. Through data analysis, the water channel in the East Africa region is determined. The moisture transport from the Indian Ocean is the main source of the water vapor for precipitation in "short rain" season from October to December (OND). The variability of the moisture transport directly results in the variability of precipitation in OND. The local soil moisture, which directly connects to evaporation, does not substantially contribute to precipitation in the region. To investigate the physical processes of the variability of the moisture transport, five seasonal simulations from September to D.
