MED: 'Tropical Cyclone Report' from TS 90M ("Trixie")

#1 Postby Vince_and_Grace_fan » Wed Mar 15, 2017 1:24 pm

Hi folks!
Today I finished my 'Tropical Cyclone Report' from the Mediterranean TS 90M (which got the name Trixie from some European media) that include a synoptical and meteorological part as the NHC's TCRs, and it contain an analysis based on the ECMWF high-resolution re-analysis data too.
The report is available here (if the link doesn't work at first, push an enter): http://zivipotty.hu/trixie.pdf
The animation of the re-analysis maps attainable from the report or from here: https://www.youtube.com/watch?v=w4x_c9wcn9w
I hope you enjoy it, and also the report is professionally correct. :)

I skimmed through it, and it looks pretty good! Though the color scale you used on page 11 is very jarring to me; I usually associate red with Category 4-5 hurricanes, not 55-knot tropical storms. (Then again, Trixie probably is the equivalent of a Category 5 in the Atlantic...)

Excellent report. Was that ship in the absolute maximum winds? Otherwise I would have set the peak intensity to 60 kt.

Thanks!

bg1: The maximal intensity of these cyclones is mostly equivalent with strong tropical storms or rarely Cat 1 hurricanes, so I think that the use of the Saffir-Simpson scale as a color scale is needless. Thus I adjusted the color scale to the wind speed values.

CrazyC83: Yes, the 54 knots ship report on 28 October was the strongest available wind data (if you mean that), but that was maybe a wind gust because it is relatively high compared to the other measurements in the nearby hours, or maybe a strong thunderstorms caused a short wind strengthening. The maximal intensity of the cyclone was perhaps closer to 60 knots than 55, but based on the ASCAT pass map it is not clear. I stayed with 55 knots because the instensity of the convection slowly weakened through the second half of the night although the cyclone's structure became better organized, and the eye-like feature also was short-lived and not fully closed.

That's what I meant by comparing Trixie to a Cat 5. A 55-kt Mediterranean TS would be an impressive feat, as rare as a Cat 4-5 hurricane in the Atlantic.

For some reason, I'm getting a 403 Forbidden error when trying to access the report.

I don't know what could be the problem (sometimes I also can't open the file firtsly, but if I push an enter, then it is okay).
I made a short TCR web page on my website, please try to open from here: http://zivipotty.hu/tcr.html
I also put there my other two reports - from TS Rolf (2011) and STS Qendresa (2014).

Re: 'Tropical Cyclone Report' from TS 90M (Trixie) - updated with SWH data

#9 Postby Vince_and_Grace_fan » Sat May 20, 2017 10:29 am

I noticed that Altimeter data have became availeble on the NOAA Ascat page ( https://manati.star.nesdis.noaa.gov/datasets/SGWHData.php ), so I updated Trixie's report (the storm surge part) with it.

Unfortunately the description of this product is unavailable on the website, and I never saw or used it previously, so somebody knows how reliable is this measurement? I mean that the measured wave heights around the cyclone are proportional to the estimated and measured wind speedds?

Kudos on a very impressive and interesting write-up!
