Obviously you did not read or understand the first message of this subject ...

I do not understand: it is about accumulations of rain from March-April-May, in Paris.

1) The Zouave has nothing to do with it, because it is the watershed, which goes to the Vosges, which determines the water level in the Seine. If it rains on Paris, I do not think it wets the balls (it's for rhyme) Zouave. Just his head.

2) March-April-May is not the usual period of great floods ...

3) If we reflect here on the question of an influence of global warming on precipitation, we cannot exclude a "slippage" in time. Monitoring of phenology (stages of vegetation) shows very clearly that certain natural phenomena occur much earlier. We have almost saved a month for the harvest!

4) Finally, we can, at "constant average height" (over a month, or several months), have much higher peaks. It suffices, for that, that the phenomena "become extremized". 300 mm of precipitation over 3 months, it can be 20 days at 15 mm, without any overflow, or one day at 250 mm, with a severe flood, then another at 50 and then nothing. My conviction is that when it comes to precipitation and winds, it is more extreme. The mud "pot"! Floods are peaks.

5) The regression curve has not been set. But to the eye, it goes up only very weakly. Which would mean that the bias, because of the reference that is not the same on the maps put by Christophe, is only very low: a few%, at most [the average rainfall over the two reference periods must to be neighbors].

It came out of its context which was previous page and which did not speak of flood but of:

Here are some photos of Sedan, nothing dramatic except for the Campsite (in 1995 all the old center was under 1m water) ... but it is impressive anyway ... many cellars are flooded ... of course. ..is by infiltration either by repression of a manhole ...

I even found strawberries from Meuse ... : Cheesy: : Cheesy: : Cheesy:

The recession is started since 24h approximately (-20cm)

Ahhhhhhh finally an article that talks about précipitations: https://www.lexpress.fr/actualite/socie ... 80351.html

Some 282,5 mm of water fell on these two months, in average cumulation on the country, beating a record which dated from December 1981-January 1982.

As water, water everywhere. France has seen in these two months of December-January an average cumulative rainfall record since 1959, the year of the beginning of the modeling of rainfall, said Monday Météo France.

(...)


Uh if the rainfall modeling dates from 1959 ... how did Météo France make the maps of 1910? : Shock: : Cheesy: :?:

JT of 20 h, France2 tonight

From memory:

- precipitation record dec / jan in Paris since records exist
- only 1935 has exceeded the peak of precipitation of these days on Paris - I do not know if in 24 h ...

Anyway, the "precipitation" aspect that you underlined was mentioned ...

Yes Didi, they start talking about precipitation and it's not too early !! : Cheesy:

A bit everywhere as I just posted it:
