Analysis of Hydrometeorological parameters in a context of climatic change in Forest Guinea

This study is devoted to the evolution of agroclimatic risks (through the evolution of hydrometeorological parameters) associated with recent trends in the rainfall regime in Forest Guinea.The statistical processing of meteorological data collected at the National Directorate of Meteorology (standard deviation, arithmetic mean and rainfall index) led to the following results: in the chronicle of annual rainfall accumulations (PRCPTOT), the upward trend is more marked in the stations of Kissidougou, N'Zrkor than that of the Macenta station.Regarding minimum temperatures, the trends indicate an average ten-year increase in N'Zrkor, Kissidougou and Macenta.Regarding maximum temperatures, the trends show an average ten-year increase of in Macenta, N'Zrkor and Kissidougou.The seasonal trends in the three stations studied indicate an increasingly early start and an increasingly late end for the rainy season.The analysis of maximum temperature anomalies shows that in Kissidougou, the period 1981-1998 was cool and the period
