Abstract
In a context of global climate change, the study of regional climate and its evolution appears essential to understand the threats to regional biodiversity. Any climatic study is based on data collection, to carry out this work we studied the climatic parameters (precipitation and temperature) of the station of Sidi Slimane, we studied the climatological data coming from the national meteorological direction of Casablanca.
The climatological characterization of the Sidi Slimane region during the period 2009–2018 has experienced a period of low rainfall particularly in the years 2017 with a minimum of 163 mm, where the recorded rainfall is the lowest in the last 10 years, in fact it is a period of persistent drought known in Morocco (meteo-Morocco) The period 2009– 2010 is the wadi Beht period of heavy flooding on the plain of the Gharb, with a maximum of 1400 mm in 2009. Linear regression analysis shows that the average annual rainfall decreased by 101.1 mm/year, i.e. a decrease of 1011 mm for 10 years. As regards the evolution of the mean annual temperature, the year 2009 is the coldest year (T min: 6 °C) and the year 2016 is the warmest (T max: 46 °C), in comparison with the mean annual temperature (25.88 °C) during this period. The result of the linear regression analysis shows that the annual temperature has a general decreasing trend (−0.22 °C/year), i.e. 2.2 °C over 10 years. The decreasing temperature trend observed at the station is related to a decrease in monthly and annual minimum temperatures.
