Title: Super Typhoon Jangmi
Post by: Carlos E on 28 September 2008, 11:39:28 AM
This is a very impressive storm on satellite now. Probably the best looking symmetrical storm this year (or since Cyclone Monica).

Current Pressure: 904hPa
Category (Saffir-Simpson): 4
Winds (1 min): 135knots

EDIT: This storm is an absolute masterpiece atm, this is what all Tropical Cyclones strive to become.

BUT  here's the scarey bit .... Gusts to 165kts  thats  305km / hr  !!!!!!

definately deserves the given status of Super Typhoon
Philippines is lucky to miss yet another major typhoon this season
My inlaws stay safe  :)

PS  ohhhh btw  Carlos ..... its a typhoon  NOT a cyclone  :)  typhoon nth Pacific,  cyclones sth Pacific

Huh? >_<

They're all Tropical Cyclones. No matter what basin. Typhoon is just a term they give them after a certain strength. >_>

No, thats incorrect ....  Southern Hemisphere,  a cyclone (low pressure system)  rotates clockwise  hence ANTIcyclone
 (High pressure system)  rotates anticlockwise

BEFORE the get named typhoon, hurricane or cyclone   
they are first a TD  ... Tropical Depression   or a TS ...  Tropical Storm    and those two definitions ARE used regardless
of the basin they form in.

its a small point BUT its important   :)

you could call our sthrn hemis.   LP systems typhoons or hurricanes if you like,   thats ok   as the name doesnt define
the rotation direction of the system
BUT by definition ...   a cyclone is a clockwise rotating low pressure system,  regardless of size,  and you WONT find
 those in the nthrn, hemisphere !!!!!

Any Hurricane/Typhoon is a Tropical Cyclone, in any basin. It's the same as saying they're a low pressure system, which they are. Tropical Cyclone, is the scientific name for any system past a certain strength in the tropics in any basin. Both the National Hurricane Center (who call them Hurricanes past a certain strength) and the Japan Meteorological Agency (who call them Typhoon past a certain strength) still have the Hurricane/Typhoon warnings listed under a Tropical Cyclone RELATED warning. There is absolutely nothing incorrect about calling this (or ANY other Hurricane or Typhoon) a Tropical Cyclone, because that is exactly what it is.

We call them Tropical Cyclone (name), but that has absolutely nothing to do with the rotation of the storms in comparison to the Northern Hemisphere; we don't call them that because they spin a different way. The best example of this, is the North Indian Ocean - they call their storms Tropical Cyclones, and yet, they spin in the Northern Hemisphere and obviously rotate a different way from the Southern Hemisphere. It's just a generic name for any of these storms.

National Hurricane Center (http://www.nhc.noaa.gov)
Japan Meterological Agency (http://www.jma.go.jp/en/typh/)

These are the official United States and Japanese sites regarding this; you will notice on both maps, it has "Tropical Cyclone Related Warnings" or similar.

Jangmi has weakened a little in the past 24 hours, certainly doesn't look as impressive as it did this time yesterday. Which is good news for Taiwan actually, since a landfall is expected in the next 24 - 36 hours.

I fully agree with you John, I find it quite odd to have three different names for what is exactly the same process. It does end up causing some confusion. Keeping on track though, from what I understand, this is really a powerful storm, I have read that it is the strongest typhoon since 1995. It's a shame that typhoons don't get the same media attention as hurricanes, there is a real western bias in our media unfortunately.

I tend to agree with you Mike T - the news media is W biased too much, but if it weren't for all of us intrepid storm chaser forum-er's then sometimes we'd all miss good looking storms like Jangmi.
In saying that, I wouldn't be too surprised if the Eastern media has been keenly watching this storm as it may have some more significant impact for Taiwan and China down the track.

Another video from James Reynolds - the UK chaser who's captured his third big typhoon this year there - talk about adventurous!

And just to jump on the band wagon with the comments re cyclones - even whilst watching the US hurricane events on live stream TV from four different media, all the meteorologists called them 'cyclones'.  Annoying that there are different terminologies for them, but it's a cultural thing also as per - 'typhoon' comes from the Chinese (pinyin: tái fēng; Jyutping: toi4fung1). Also In Greek mythology, Typhon (ancient Greek: Τυφῶν, Tuphōn), also Typheus/Typhoeus (Τυφωεύς, Tuphōeus), Typhaon (Τυφάων, Tuphaōn) or Typhos (Τυφώς, Tuphōs)

They're all cyclones.  It's their locale that gives them their relevant ' storm title'.  In the US they don't call winds  anti-hurricane  but anti-cyclonic and not anti-typhoon but anti-cyclonic or cyclonic.

That video is amazing. What mammoth waves! Luckily it weakened a fair bit before landfall, but still an extremely powerful Typhoon.
