China3d... Videos of a new storm today...

... or if is not a TVS, at least a very strong meso. Conditions are perfect for isolated strong/severe storms today, with plenty of shear, especially to the north of the region where there is a subtropical divergent jet stream passing by. I need to chase one of this cell sooner or later... :lol: :lol: :shock:

Here's the images and the loops:

Looking like that Western cell could be becoming supercellular... hopefully it stays descrete for you unlike that cell that developed nearly right on top of you...

When all the boundaries that formed that day weakened all storms ended :lol: There was plenty of gasoline at the low level and after reviewing many times the radar I'e found that all storms were initiated by boundaries. The one I got overhead formed on a gust line descending from a strong cell from the north (velocity > 20 m/s, that's why it formed so quick...).

Today can be an even better day, with jet stream descending from the north.

Upper Jet is steadily descending in latitude from the north, and maybe this evening will be over southern Guangdong on this lake of gasoline:

I figured out to make the convective outlook for severe t-storms by myself :lol: :

Considering latest development in pressure pattern and satellite maybe the mdt could be extended a little southward later in the day. Overheating is spectacular, even too much.

Things are gonna get destabilized quite fast, also in the SLGT area, rock hard convection bubbling everywhere. Get this !!

Pressure dropping. Winds intensifiying from the E-SE now. Later I'll post the serious radar. The one posted is always the latest one.

:wink:
 
Wind storm now, gusts around 45 kts from the east, maybe an outflow boundary aided by new inflow..., shit I lost a tree in the garden :lol: :?
 
Back, this storm is gonna damage some place around here...

The storm has an RFD, that is now blowing here, not very strong, maybe 15/20 kts from the W-NW. Very nice to see just a few hundreds meters to the east flags blowing north, while here blowing south...

:wink:
 
Another storm setting in from the W-NW !!! Many IC lightning now, mammatus well visibile despite is a bit dark. Dews steadily around 25. All radars out of service so I cannot see what's going on... :?

:wink:
 
Everything ended up with a spectacular anvil crawler (hope it's written correct) show, with almost 2 hours of lightnings fading softly, broken only by one or two CG nearby every few minutes.

It's a typical "fireworks closure" here in my place, but more common in June than May...

:wink:
 
Yeah, I was thinking the same thing. :) You might even drum up some Chineese tourism. I don't think many people here (especially me!) had any idea that supercells and China got along with each other.

Awesome stuff as usuall. C'mon, plains! Get your act together! We're getting shown up by eastern China!

:D

Yes, I will for sure, need to arrange some material, but I will. However, I think I will start with typhoons at first, is much easier than t-storms, and here we should have no problem in getting them... with an average of 8 per year in the Soth China Sea. In 2003 already experienced some. This is the outlook for this year:

http://www.hko.gov.hk/wxinfo/season/season.htm
Number of tropical cyclones affecting Hong Kong
10% chance 3 or fewer
70% chance 4 to 6
20% chance 7 or more

The t-storm series with a westerly flow aloft will end soon, maybe in the first 10 days of June, then will start the 100% tropical season, with strong storms, but tropical, so "go up and fall down" :lol: Anyway, this storms are capable of very powerful downbursts and incredible gust fronts where they hit, but as far as usually they are slow moving, they tend to concentrate in small areas and die soonafter. Got hit by one last year, the downburst was so violent that include also small hail (hail with positive temperature at 500 hpa.......) and the wind so strong that the rain was sprayed into the windows even they were closed :lol:

:wink:
