Hi there (bonjour tout le monde!)
Since august 2020, south of France (area between Montpellier and Marseille) has seen a huge amount of rain days or very cloudy days, which is very unusual (mediterannean climate is rather dry and no clouds). Lots of lows centered near portugal and spain seem to causing the rain, but usually lows are centered in Biscay, and hit the north of the french west coast. It's been more than 6 months now that the weather is rainy and cloudy with these lows centered way more south than usual, and often moving across spain into the med ( more rain...). Does anyone knows what is causing these lows to be so down south and able to go across land (Spain/Portugal)?? The jet stream seem to have been very low down south, but what is causing the jet stream to be at such a low latitude??
If anybody knows, thanks a million to share! :-)
