Analysing the relationship between wind patterns and rainfall received in Kampala district, Uganda

Abstract

This study analyses effects of wind on the rainfall received within the spatial areas of Kampala. The wind speed in and rainfall received in Kampala does not vary too much and therefore the effect of wind in the rainfall received in Kampala District is merely negative. Rainfall has a significant effect on the economic and social activities of the people of Kampala such as infrastructure, livelihood, water supply and sanitation and many more. Therefore, this research looks upon how wind can also have a role to play in the rainfall variation in Kampala district which may bring about the hazards related to rainfall. According to the results generated in this research wind has relatively no effect on the rainfall received in Kampala for example Makerere having 1.5% and Act Together having 1.9% effect of wind on rainfall, Mengo 7.2%, Ware house 4.8%, and Rubaga having 4.0% effect of wind on rainfall hence the wind direction and speed does not vary much with rainfall in Kampala District. This can be attributed to the presence of wind breakers such as tall buildings, and trees which breaks the wind speed leading to limited effect of wind on the rainfall received in Kampala and thus the Null hypothesis is achieved in this study.
