dc.description.abstractThis study investigates the variability of extreme climate events over Kampala using indices from the World Meteorological Organization (WMO) Expert Team on Climate Change Detection and Indices (ETCCDI). The analysis was based on observed daily temperature and precipitation data from one station for the period (1985-2020), the historical period (1971-2005) and projected daily temperature and precipitation data (2021-2080) was obtained from Coordinated Regional Downscaling Experiments (CORDEX) archive. Generally, the trends and patterns in temperature extreme events across Kampala City indicates a general increase in number of heat wave events and a general decrease in the number of cold wave events. Variations results in temperature extremes in the future under RCP8.5 for Kampala city showed that the city will experience positive increasing trends in the warm days and warm nights while decreasing negative trends will be observed for the cold days and cold nights. These trends (positive and negative) are only statistically significant (P-value <0.05) for warm days, warm nights and cold nights. Thermal heat comfort indicated that in the historical period (1991-2005), the city experienced cold thermal sensation in 1998 as this was also recorded to be an El Niño year. Furthermore in the historical period, a negative decreasing trend in thermal heat comfort was observed and was not statistically significant (P-value >0.05). On the other hand, positive increasing trends were observed in the current period and the future period though statistically significant trend will be observed in the future period compared to the current period. Generally across the three study periods, Kampala experienced comfortable thermal sensation category of thermal heat, though the future is expected to nearly fall in the hot thermal sensation category of thermal heat comfort. The changes give a possible indication of the ongoing climate variability and change especially on an urban heat island of Kampala. The results form a basis for further research into how the thermal comfort therein is affected by the variations in the number of heat waves/cold waves, the number of warm days/nights and cold days/nightsen_US
