Extremism in climatic phenomena foreshadows the harshness of the coming winter in Morocco

With the approach of the autumn season, which is usually characterized by fluctuations in cold weather, as well as the occurrence of thunder and torrential rain that left torrential downpours that claimed the lives of some citizens in remote regions of the Kingdom, the debate is being raised once again the ability of Morocco to adapt to the climatic changes that are developing towards more violent and renewed phenomena, in time and frequent in many places.

As soon as the Kingdom emerged from a summer season that witnessed record heat levels and a wave of successive “mass fires” in the northern half of Moroccan soil, it found itself facing further effects of “climate extremism” transformations leading to “catastrophic events” that often leave material and human losses.

Mohamed Said Karrouq, professor of climatology at Hassan II University in Casablanca, noted for the first time: “The relevance of questioning and discussing in this exact circumstance”, explaining that “the autumn season is still very difficult in Morocco, especially if we have take into account that the most dangerous floods that have historically happened.” In Morocco, it happened in this season (especially the months of September, October and November).

Qarouq added, in a statement to Hespress Online, that floods and thunderstorms are “originally a natural rule, but in recent years they have begun to take on more violent and extreme manifestations.”

The same climatologist pointed out that “with global warming and the acceleration of the increase in the planet’s temperature, the water cycle has moved to another position, faster, more acute and more massive; In other words, climate change adds another problem to the problem, which is the additional violence due to the abundance and abundance of water.”

In his speech, Qarouq said that “if we are at the gates of the astronomical autumn season, which begins – as is known – on September 21 of each year, then the start of the natural autumn season is more related to a stage ; It takes a chunk out of summer and can rush into winter when it’s over.”

He explained that “this stage is characterized, from a natural point of view, by the process of decreasing the energy budget in the northern part of the globe so that it increases in the southern hemisphere, after balancing during the autumn season above the equator”, pointing out that “this process is of great importance in the water cycle that is related to temperature, which is a product of the energy balance”.

He explained: “We are leaving the hot summer, which is characterized by high evaporation from seas, lakes, dams and forests, since the evaporated water returns to the atmosphere at a stage of its development; And when the temperature on earth decreases, with the arrival of the cold seasons, these evaporations from the air (millions of tons of water in the air) begin to return as moisture carried by rain”, pointing out that “the decrease in temperature it leads to the inability of the air masses to transport this amount of water, and the result is a return. Sometimes it rains a lot.”

The Moroccan climatologist added that “for various reasons, due to a sudden drop in temperature or due to the subduction of an isolated cold air mass into the Moroccan atmosphere, this causes the return of very violent rains, which unfortunately destroy the margins of the courses. of water, especially in cities; Because the latter are originally areas of ancient watercourses, whether primary or secondary.”

At the end of his conversation with Hespress, Karouq recalled what the Midelt and Azilal regions had witnessed, including massive thunderstorms and floods, earlier this month of September, for everything that can lead to the transformation of these violent phenomena into rules. ; This is what we are witnessing in 2022 with rising temperatures, fire intensity and frequency, as well as winds.”

For her part, Asmaa Arbaoui, national coordinator of the Moroccan Coalition for Climate and Sustainable Development, said that Morocco “is not immune to the climatic changes that the entire northern hemisphere has experienced, especially the Mediterranean region, which experienced a hot summer the Unusual, citing as the most prominent example of this, “the drought of European rivers (the Rhine in Germany) that has not been seen for almost 500 years”.

In an interview with Hespress, Arabawi called on the public authorities and the various actors involved to “be careful and take advantage of the previous years that were characterized by devastating floods, especially since every hot season is followed by torrential rains that are also record and unprecedented. ”, concluding that “the weather is getting more extreme, chapter after chapter, and will not wait for anyone to act to limit its destructive effects”.
