F * ck you Earth! Hurricanes 2017 Harvey, Irma, Jose, Katia ... Payback time is coming!

Finally 2017 was not the worst hurricane intensity season since it was measured (at least in the North Atlantic), but the trend is upwardly bullish: climate-change-co2 / what-are-the-power-and-the-energy-and-a-hurricane-t15359-10.html # p335739

Early-month study ... hypothesizes gamma radiation and positrons in Hurricane Patricia of 2015: https://agupubs.onlinelibrary.wiley.com ... 17JD027771

On 23 October 2015 at ~ 1732 UTC, the Airborne Detector for Energetic Lightning Emissions (ADELE) flew through the eyewall of Hurricane Patricia aboard National Oceanic and Atmospheric Administration's Hurricane Hunter WP-3D Orion, observing the first terrestrial gamma-ray flash (TGF) TGF gamma-ray burst. ADELE measured 184 counts of ionizing radiation within 150 μs, coincident with the detection of a nearby lightning flash. Lightning characteristics inferred from the radio signal and comparison of the gamma-ray energy spectrum to simulations suggests that this is the first observation of a reverse beam of positrons predicted by the leading TGF production model, relativistic runaway electron avalanches. This paper presents the first experimental evidence of a predicted second component of gamma-ray emission from TGFs. The brightest emission, from the relativistic runaway electron avalanche bremsstrahlung; the second, fainter component reported here is from the bremsstrahlung of positrons propagating in the reverse direction. This reverse gamma-ray beam penetrates to low enough altitudes to allow ground-based detection of typical upward TGFs from mountain observatories.

A positron is a particle ... of anti matter ...

Eventually nature will exterminate man ... before man does ...

It does not calm down, I present Mangkhut, super Thyphon category "6/5"!

[Christophe]

They arrive in Europe ...

Hurricane Leslie is moving towards Portugal: it could be the most powerful for more than 170 years.

And in 2019 Dorian.



350 km / h of gusty wind

It's going to be hot in the US

[Christophe]

Yes the value of 350 km / h intrigued me too ... in the sense that I do not think I have ever heard such a high value (280 km / h of memory?) ...

The wind power varying according to the cube of the speed between a "small" hurricane of cat 5 at 260 km / h and Dorian at 350 km / h there is a difference of destruction power of (350 / 260) ^ 3 = 2,4 times!

In other words, an increase of 34% (= 350 / 260) of the wind speed gives 240% of power in addition ... to counter, dispel, fight against ...

So as suggested above: it might be time to make a category 6 on the Safir-Simpson scale!

[Christophe]

If they continue to grow like that, in 20 years they will cover almost all the North Atlantic!

[wirbelwind262]

In 20 years, the coasts will be uninhabitable, and you can not counter a quantity of such energy ....

[GuyGadebois]

Ah, if we could use this energy for our benefit ...
