Climate: Natural disasters, related to water to be expected
According to Prakash Luchun, for Mauritius, January 1 begins with the sign of Cancer, which is the birth ascendant of our country.
“The sign of Cancer is related to the element of water. For the year 2021, not only Mauritius, but various countries of the world will be terribly affected by natural disasters, particularly related to water. "

more seriously, if I'm not mistaken, the argument that the RCA would promote extreme precipitation would be that the warmer the air, the more moisture it contains. I understand that this argument plays out when we have tropical cyclones forming on particularly warm seas, but you find that it has been particularly hot in recent weeks in Europe? all the explanations of the current weather situation speak of a COLD drop that hovers over Europe and causes series of bad weather, so what has to do with the fact that HOT air contains more humidity?

I asked the question on FS we'll see .

Rain generally results * in our latitudes from the meeting between a warm (and therefore humid) front and a cold front which condenses this humidity. The cold "drop" plays this role here.
According to the Météo-France forecaster interviewed by 20 Minutes, Jerome Lecou : "When on the surface (the first hundreds of meters of the atmosphere), the conditions are rather warm and there is an overhanging phase of cold air ranges which circulate around 4.000 / 5.000 meters, you have an unstable profile absolutely favorable to the formation of convective clouds, cumulonimbus clouds, storm clouds. "

The movements of air masses (often complex) constitute a major mechanism of energy dissipation in the "thermal machine" Earth ...

* Or the cooling of a mass of hot and humid air which rises in altitude (case of the tropical climate).

[humus]

but do you think it has been particularly hot in recent weeks in Europe?

Why am I always disappointed when I read you?
Widen your field of vision. Unless you are a minister and believe that CO2 efforts in France will directly impact the climate in France, in this case would be excusable.

ok but so it has nothing to do with the fact that the air had more water than usual, because it was hotter. This is because the cold drop has parked over the affected areas, and all the water has poured into the same place, but how it is favored by the RC the fact that a cold drop is stationed at the same place. same place ?

[Ahmed]

I do not understand the objection: the fact that the cold "drop" is in one place or another is only due to the complexity of the air currents. On the other hand, if a lot of water can fall, it is because it is contained in air masses hot enough for this to be possible ...

we agree, but did the particularly strong floods that happened come from the fact that the air in contact with the cold drop was much warmer than before and contained more water? I don't have that impression, from what I heard, it just came from the fact that the chance of the currents and the pressure distribution caused the precipitation to stay in one place for hours. Bad luck for those below, but it could have happened just as well 30 or 50 years ago.

And obviously, the damage is also due to the fact that urbanization has caused more and more houses to be built on land previously agricultural or wooded, which absorbed water, and which we avoided before building in the major bed of rivers.

Of course. Before telling bullshit we find out:

The explosive cocktail:
- a heat wave in the Magreb
- a heatwave over northern Europe
- hot over eastern Europe
- a cold drop

The hot air from Tunisia goes up to Finland, then fed with hot and humid air the cold drop.

If we had not had 2 heat waves simultaneously, this disaster would not have happened.
QED.

And the more heatwaves we have, the more disaster like this one. The IPCC has been saying this for 30 years, but some remain deaf or have complete amnesia.
