Weird cyclones - Impressive cyclones

[vbhoutex]

For some reason, I loved Hurricane Frances of 1992's shape. Just one giant rainband.

Looks like some weird animal curling in on itself. There is actually a name for these invertebrates which I can't remember(I see the head shape in the clouds nearest to the center).

Frances is also unusual because, if you look at the HURDAT, it goes from extratropical to a strong tropical storm. When it weakened it did the opposite. I don't see any transition phase in NHC's data.

Hmm? Unless I'm reading HURDAT wrong, it only goes extratropical at the end. Or maybe i'm not understanding what you mean?

You're looking at the wrong Frances. The Frances being discussed is the one from 1992:

I still think Hugo had one of the best buzzsaw appearances ever.

Here's Hugo at his Category 5 peak:

[wxmann_91]

Dvorak images like this one are rare, even in the WPAC:

STY Gay at its peak in 1992. It is speculated that Gay was possibly stronger than Tip. Per this study, ODT numbers for Gay as well as another cyclone possibly stronger than Tip, Angela in 1995, hovered between 8.3 and 8.7.

[wxmann_91]

As an extension of the previous post, here's an image of Angela from 1995. Me personally, I think Gay was stronger just based on cloud tops and symmetry, although Angela's eye is smaller.




Another cyclone mentioned in the study was Yuri of 1991, considered but eliminated. However, JMA estimated Yuri to be stronger than both Angela and Gay.

[Squarethecircle]

I've never thought Dvorak numbers mean much unless they've been thoroughly interpreted (and they're not even close to accurate in comparison to recon). Since no one can go back in time for those storms, Tip is still the strongest.

Note: I've also long thought that storms with lower T-numbers can appear more impressive than storms with higher ones. Dean at one point was a category 5 and looked much better than his T-numbers did. Monica was ridiculously impressive, but didn't get as high T-numbers as Gay or Angela.

That wasn't what I was thinking of, but they definitely are similar to the picture. I think the name I was looking for is Hydra(I have weird eyes I guess).

And here is the very famous, the great, the weird, the fighting Epsilon:



Avila said: "There are no clear reasons, and I am not going to make one up, to explain the recent strengthening of Epsilon"

Epsilon! Case remains open.

I've always considered Tropical cyclone Katrina-Victor-Cindy of the 1997/1998 Australian/SWIO tropical cyclone season one of the most incredible solely because of the fact that it traversed four basins (Southwestern Pacific, Gulf of Carpentaria, Southeastern Indian Ocean, and Southwestern Indian Ocean). Tropical Cyclone 12P (Katrina) (S.S. Category 2) occurred simultaneously with the much more potent S.S. Category Five cyclones Ron (10P) and Susan (11P) in the South Pacific, then dissipated and redeveloped from the remnant low in the Perth AOR as TC Victor, then eventually crossed 90 degrees East into the La Reunion AOR and was briefly renamed Cindy (officially referred to in records as Tropical Cyclone 22S (Victor/Cindy)). Victor/Cindy achieved MSW of 90kts while located northwest of Australia.

An unusual hurricane was Antje's hurricane in early September 1842. The storm was named after a ship that was damaged in the hurricane.

Antje's hurricane was unusual because of its path. The storm formed east of the Bahamas and moved due west into the southern Bahamas. Continuing on a due west course, the hurricane moved in between the Florida Keys and Cuba. Entering the Gulf of Mexico, the hurricane continued on a relatively due west course and eventually made landfall near Victoria, Mexico.

One of the possible explanations for the hurricane's due west track is an intense high pressure system over North America that prevented the hurricane from moving north.

Dvorak images like this one are rare, even in the WPAC:

STY Gay at its peak in 1992. It is speculated that Gay was possibly stronger than Tip. Per this study, ODT numbers for Gay as well as another cyclone possibly stronger than Tip, Angela in 1995, hovered between 8.3 and 8.7.

I read that STY Gay was very intense, but relatively small for a typhoon. I read it had a central pressure of 872 mb based on Dvorak. It would not surprise me if it had lower pressure, like around 865 mb.

Dvorak number was WAY OFF with Hugo and Wilma. In fact the Hurricane Hunters nearly got killed in Hugo because of it. Wilma had a Dvorak scale of 6.0 to 6.5 at her peak of 882 mb and 185 mph. Dvorak is flawed in regards to pinhole eyes.

"IT WOULD BE NICE TO KNOW...SOMEDAY...WHY THIS HAPPENED."

TS Allison of 2001. It was never suppose to form, yet it overcame it. If it had stayed over GOM longer, it would of been a hurricane.

Huh? Those images were of Humberto. Plus, the quote's from Humberto's discussion. Were you adding Allison or was it a goof?

Okay, it was a goof on my part for mistaking the image as Allison. However, I was addd Allison to it as well.

Sorry the weirdest one must have been Typhoon Vamei that formed 1 degree north of the equator end December 2001 in the South China Sea!
