Why do depressions keep coming?
The country has now been experiencing rough weather for more than two weeks. How can we explain this phenomenon? “Depressive rails” are currently present in France: depressions follow each other closely because they are under the influence of a “zonal flow”, that is to say ;-say a "jet-stream". The latter is currently very powerful, because it blows at high pressure. more than 300 km/h and is heading towards the country. The current jet stream has other particularities: its flow has been uninterrupted for more than two weeks and its trajectory is rectilinear, which makes recent storms more violent. "This situation is explained by a westerly current to the south. southwest which is well anchored; over Europe”, details Météo-France, which specifies that this current "acts as a highway for disturbances which can circulate freely.".
