New Phenomenon Dubbed A "Sting Jet" Recently Disco

Thought I would share this with everyone on the boards:

This has been known about for a few years by the Met Dept. at the University of Reading. Prof Browning is the person who found and named supercells by the way over southern England.

Before you ask yes I'm a student there, just home for Easter at the moment.

Since about 2003 I think. I just thought I'd share info I found about it with people here; after all only being around three years most have never heard of it.

It can certainly be very damaging and so it is something we look out for on WV images on rapidly developing cyclones.

I wonder if it occurs in storms in other parts of the North Atlantic. I'm especially interested in cases where a hurricane and a Nor'Easter (extratropical low) merge to form a new rapidly deepening storm center. I would suppose something like the above, given the right set of atmospheric conditions, could create a sting jet like feature of marked severity; given the ingredients needed are basically a rapidly sinking jet of cold air colliding with insatiable rising warm air. I'd be interested to hear your thoughts on this issue P.K.

Possibly, but if you have a hurricane say heading north along the east coast of the USA with a baroclinic low say off the coast of Canada then it is likely to move east. So if this system does bomb (Drop of 24hPa or greater in 24 hours) then the sting jet will be over the ocean and so likely go un-noticed apart from in WV imagery. The difference here is if we get systems close the UK bombing then the sting jet can do a lot of damage if it passes over the UK.

So yes no doubt it does happen the way you say but it probably go un noticed. I haven't read up much about this but it seems reasonable that no matter where a barolinic low is if it develops rapidly enough there could be a sting jet.
