Peculiarities of Climate Change in Central Africa

The multiyear series of mean monthly air temperatures at 65 meteorological stations in Central Africa are considered to assess the influence of climate change on the dynamics of multiyear mean values. Due to the spatial and temporal heterogeneity of observations, a methodology based on a sequential transition from more reliable to less reliable information, the assessment of the stability of nonstationarity indicators, the selection of areas homogeneous in climate change dynamics, and the quantification of the changes occurred depending on the type of mean value change and on the choice of effective climate models was developed. As a result, we received quantitative estimations of air temperature growth in different seasons, which reach 2.2–2.4 °C in southern mountainous and eastern regions in all seasons and summer monsoon in the coastal areas and spring intermonsoon period in the north. In the central part of the territory, the growth of average temperatures does not exceed 0.5–0.6 °C. Efficient climate models were also selected for the territory for the forthcoming assessment of future temperature.
