understood. Has a tropical storm/hurricane ever happened, dropped rain, reduced in strength, then returned to the tropics to become a major storm again, at least in knowen history?

Can't find any. Wind patterns in the Atlantic would strongly discourage this. Maybe a Pacific or Indian ocean cyclone?

 

[Scott DeWar]

True that. Currents would head northward from there with the gulf stream. Am I correct on this?

Returned to the tropics? No.

Been a tropical storm, become a hurricane, drop back to tropical storm, and then step back up to hurricane strength? Yes.

So, let's talk about the weather

Hurricane Patricia is now Cat.5 with 250 gusts, 200 sustained winds. the pressure is 880millibars or 25.98644 inches. That is the lowest pressure I have ever heard on the surface of earth. Um, WOW?!?

Comments?

The end is nigh?

Some information here:

"‘Potentially catastrophic’ Patricia becomes strongest hurricane ever recorded, to slam Mexico today"

https://www.washingtonpost.com/news...patricia-to-slam-west-coast-of-mexico-friday/

The Category 5 storm’s maximum sustained winds have strengthened to an astonishing 200 mph. “This makes Patricia the strongest hurricane on record in the National Hurricane Center’s area of responsibility (AOR) which includes the Atlantic and the eastern North Pacific basins,” NHC said early Friday morning. “The minimum central pressure estimated from the aircraft data, 880 mb [down to 879 mb at 2 p.m. Friday], is the lowest ever for our AOR.”

A (small) plus, the region experiencing the highest winds is small, limiting the damage. The total energy is 25-50% recent large storms (Katrina, another that I don't remember).

I'm sure there will a lot of additional news.

Wikipedia tells me:
"The lowest non-tornadic atmospheric pressure ever measured was 870 hPa (25.69 inHg), set on 12 October 1979, during Typhoon Tip in the western Pacific Ocean. "

Comments?

Thankfully, "the most powerful" may not be "the most damaging" in a human sense. Here's hope for the people in harms way...

I noticed the population of the area seems sparse. I also figured the pressure is not the only determining factor for damage, but it sure does not help.

Hurricanes Camille and Andrew were rather nasty gusts of wind too.

Andrew: highest winds: 175

lowest pressure: 922 mb /27.23 in

Camille:
highest winds also 175 MPH

lowest pressure: 900 Mb/26.58 In

I remember H. Elene and Kate, as I was preparing to move to Biloxi, Mississippi when Elena hit and all my friends were teasing me about being sure about my move and Kate hit while I was there - and the winds were nothing short of frightfully impressive, even though we were not near the eye.

 

[tomBitonti]

Isn't there a cubic factor (V^3) for wind/current, because not only is the energy per unit volume increasing at (v^2), but also more unit volumes (at a rate of v) are passing by? I remember reading something like that for water currents, and would expect the same for wind.


Thx!
