Interesting development in SE China (ended)

[Simone Lussardi]

Hi everybody,

We got an interesting set-up in Sern China today. This is from 08:00 AM local time, things are going to change very rapidly as the day heat build up. Dews are in order of 25C, with constant deep sfc flow from the SSE well inland.

Look at this:

Bye, :wink:

[Simone Lussardi]

Ooops, got a cell developing too early to my SW (I am at the edge of the gulf in the middle).

http://www.weather.gov.hk/wxinfo/radars/rad/ra256_20050504_1148.jpeg

Anyway seems this is not hindering the heat development quite much, as now I record:

Mostly cloudy skies
T: 87F
Dew: 73F
Ur: 62%

:wink:

Wow...very interesting too see storms in that area...i usually only hear about the weather in the USA. Very cool!!! :shock:

[Bill Hamilton]

Interesting but I don't think I will chase that one. :lol:

Hi,

This zone of China is a miny alley, both for supercellular storms (with hailstorms and tornadoes) from March to late May and typhoon-spawned tornadoes from July to October.

Anyway, this storm is getting organized :shock:

Definitely not, is too early and is only rain and maybe hail. :?

The attached image has been captured on a supercell on April 25th that lasted for hours and crossed the entire radar from W-NW to E-SE (with SW flow aloft.... so right deviating) and devasted several locations with hail and very high wind, and flooded many others.

That was more interesting... :)

Just when I thought I'd seen everything, I find a freakin' NOW thread on Stormtrack for southern CHINA -- and a chaser down there gearing up to go. This truely is a wonderful website.

That morning storm ruined the games, but now the anvil prp are helping the atmosphere to get even more humid (dews increasing !!).

Is clearing now, if the sun come out we'll see more action coming up at noon. New storms building about everywhere.

The south edge of the anvil extend up to my head (the center of the radar). Of course I am referring to the nice developed hook.

:lol:

Simone,

Can you supply a Web URL to those (and presumably other RDA sites) WSR-98D images?

Simone,

Can you supply a Web URL to those (and presumably other RDA sites) WSR-98D images?

Yes:

Reflectivity:
http://www.grmc.gov.cn/tqsk/gzrad_r.asp

Base velocity:
http://www.grmc.gov.cn/tqsk/gzrad_v.asp

Radar of HK (reflectivity only):
http://www.weather.gov.hk/wxinfo/radars/radar.htm

Unfortunately that's it... :?
Maybe in the future they will improve the radar system. Sometimes (when very serious conditions appears) they publish other radar images, zoomed very in detail and with very high quality, also with some warning marks drawn on the base map.

:wink:

[Karen Politte]

Wow.

Nice to see that almost every country's government supplies free radar images......except the UK. :? Noooo.....us British have to "guess" what's around the corner......if you want anything more detailed than dumbed-down TWC (minus satellite and radar) info you're out of luck.

Anyway China is very sensitive to weather, since it is strike constantly every year by severe weather during the spring and summer.

I read somewhere they are going to extend radar nationwide.

:wink:

That program is well underway, the CINRAD network, comrpised of WSR-98Ds supplied by Lockheed Martin. These are very similar to WSR-88Ds, with similar RDA and OPRG systems. A similar network was installed in Romania, giving that county the most advanced European radar network (these are S-band radars).

Thanks for the confirmation ! And thanks for the PDF, saved and reading now. If you find any link about this pls post it, as I will if I find... with my poor chinese I'll try to translate some chinese docs.

Anyway, better I call some friend and tell them to stay at home tomorrow :lol: :lol: :lol: :shock:

chasing storms on bicycle?? RofLmaO

Sorry but I had to do it.

[David Wolfson]

I took a bike trip through Guangdong and Guangzhou some years ago. I can vouch that when it storms there, it really storms! Not prime chase country -- that's for sure. The roads through the mountains were something else....

Yes, definitely a bad place for chasing. However now they built a lot brand new Highways across all the province, I am trying to study a map to see whether it can be suitable.

However, the "probable" supercell of yesterday spawned a tornado and a hailstorm in the area, get from the news last night. About 430 houses destroyed (so they said) and I saw many very large tropical trees break in the middle. I guess F1/F2 ? The hail was about 2 inches, guessed from the holes in roof of some houses....

If I find some web pictures I'll post them.

:wink:

[Simone Lussardi]

And this is now !

http://www.grmc.gov.cn/leida/gzradr/GZR200505050158.GIF

Here is sunny and hot (already 30C with dews nearly 25C).

:wink:

[Ryan McGinnis]

Yikes -- you're making me crave a Chinese chase vacation. :) That really would be a blast.

[APritchard]

Wow! Some great looking cell's out there!

[Simone Lussardi]

I lose the count of the supercells that exploded today !!!!! :shock:

Very strong sfc flow (some HK stations are reporting GALE force winds, up to 35 kts) and dew-point well established into the 25°C.

Here some of the latest radar shots:

The sfc deep low pressure system is dropping southeast, right to my W-NW. ... Strong showers are also coming in from the south (sea) and bringing more unstable air mass to the convergence line:

[Simone Lussardi]

This more than suspect cell completely crossed a big city, QINQYUAN, the city of the sounding...........

http://www.ghidini.cn/__tmp/supercella_qingyuan.gif

Tonight I'll check the news again.

Anyway, that sounds like a lot of destruction from that tornado. I hope that injury and death were minimal to zilch, but I suspect that if 2 inch hail is putting holes in the roofs, that there is probably not a lot of confidence in the structure of the buildings unfortunately.

Definitely poorly constructed buildings in the country side. :?


:wink:

[Simone Lussardi]

The strong storm in the center is right to my north, now is dark and the lighting show is simply unbelieveable, I cannot count how many lighntings per second, the sky is practically switched on !! :!:

Low clouds fractus inflowing in the storm at a very rapid speed.

Oh God, is exploding ! Very populated North area of Guangzhou capital is right in the path of this storm. The purple color is > 300 mm/h, sorry but this radar is not so professional...

Those storm look awesome from radar. Better than anything here in california!!

It is everything but finish, this is the latest shot:

http://www.weather.gov.hk/wxinfo/radars/rad/ra256_20050505_2248.jpeg

Is gonna be a long night... Seems to the far north everything is merging into a huge MCC/MCS, while to the south of the convergence line storms continuously fire up. The provincial government issued red and black (maximum) rainstorm warnings for half a region... :shock:

Those storm look awesome from radar.

:)

In real the visibility is often not so good cause the very high humidity down here, so they are not very photogenic :(

Anyway this year I have a digital camera and I'll try to catch a chinese storm. Sometimes it also clear up a bit and shows many storm details.

:wink:

[Simone Lussardi]

Everything is squalling out :lol:

http://www.grmc.gov.cn/leida/gzradr/GZR200505051454.GIF

If you see the loop you can see that squall to the NW is moving E-SE:

Simone, I just wanna thank you. This has been the coolest thread I've read anywhere in a long time. I hope you do this for all the good storm setups you get out there. :)

Ok :D Happy to hear that.

The next low pressure system is already forming in the back of this one. From the maps it should be a little stronger due to more thermal monsoon effect of the central and northern China.

By the way, last night got several passages of squalls with heavy rain, little hail and strong winds. Temperaure and dews dropped considerably. Everything lasted about 5 hours....

:wink:

[joel ewing]

Simone...that was fantastic!! What an eye-opener for me! Please....keep updating us in Storm Track when you get more action like that.
I'm serious.......with each successive shot my adrenaline kept rising and rising. I'm blown away!! I never would have guessed that you get that type of tornadic weather in China.
And I agree..........what a great forum this is.
Thank you again, Simone.

Thanks very much to you also :D

I will make you happy very soon :lol: , this is the analisys for next week:

http://www.hko.gov.hk/wxinfo/currwx/fnd.htm
THE TROUGH OF LOW PRESSURE NOW AFFECTING THE NORTHERN PART OF THE SOUTH CHINA SEA WILL WEAKEN IN THE NEXT COUPLE OF DAYS. ANOTHER TROUGH OF LOW PRESSURE WILL BRING UNSETTLED WEATHER TO CENTRAL AND SOUTHERN CHINA EARLY NEXT WEEK.

The part marked in bold is to point that the position of the trough (extending from central China to the SW towards southwestern China) that here is simply perfect for severe weather, with W-NW flow aloft and strong S-SW flow at sfc.

Dews are never a problem around here: 8)

Thank you so much for sharing all of this!

Australia is still working on getting doppler radar around the country. I believe that there are a few currently in operation, but it's not a nationwide thing yet. They're also working on getting a mosaic similar to what we have in the US.

Hi there ! Thanks to you also :D

I guess, considering how much severe wx you got over there, they'll complete the project very soon...

Hi there,

I am now looking at the news on the net.... Trying to translate some part but seems that this low pressure, since May 2nd, brought many tornadoes across central and southern China (even in Taiwan) !!! :shock:

Just put the link here if someone got a good automatic translater. I don't have a good one, I can just read some words and guess the article. The chinese keyword for the search is tornado.
