Urban climate variability trend in the coastal region of Mombasa Kenya

Abstract

The world population in global south countries is increasing. This fast growth has heightened urban ecological footprint that contributes to anthropogenic forcing triggering of the climate system. From this study, climate variability trend dynamics in Mombasa County, a coastal urban area in Kenya was examined. A retrospective study was done (1989-2019) to determine the changes in temperature and rainfall in the area of study. The results show that climate variability was experienced in Mombasa with a maximum temperature t=-5.628, df=23, P:0.000 and a minimum of t=-5.401, df=23, P:0.000, total rainfall t=2.025, df=23, P:0.275. The linear regression analysis shows rainfall variation y =-9.588x + 1217.1 and temperature y =0.0258x + 29.888 with an increase of +0.4°C. The annual maximum temperature averages show heterogeneous distribution from kurtosis coefficient with little observed skewness.

Overtime Modelled Climate Variability Effect in Roysambu Sub-County in Nairobi Kenya: A Retrospective Analysis

“…The monthly rainfall and temperature data were organised and processed in Excel spreadsheets. Through simple regression analysis, climate variability data was modelled to show anomalies and retrospective observed intercessional oscillations on data through annual, total, minimum, and maximum indices on temperature and rainfall (Ngare et al, 2020).…”
