How do you get lightning and Hail

[bwstg]

in a warm system???

[CocoaBill]

some of the tops of the clouds are going so high into the upper atmosphere - they aren't so warm anymore...........

warm CORE system......cdo is -80!!!

what does that mean, please? Thank you...

[dennis1x1]

a normal low pressure storm has a cold core...a tropical system has a warm core....

the intense convection surrounding the warm core (eye) of the hurricane is very high into the atmosphere and the temps at the tops are around -80.

First off, why scream at someone who is trying to learn something?

Second; how can a CDO over a WARM CORE system be 80°C BELOW ZERO?!

CDO is Central Dense Overcast ...

Warm Core System is a low of tropical nature and not a cold-core system which is induced baroclinically and by dynamics ...

And just because we're dealing with something that's very odd, occasionally the eyewall does produce convection that is strong enough to support lightning and in rarer forms, hail ... in which, the instability had reached a level that has allowed for updrafts strong enough that ice crystallization to produce 1) lightning, and 2) hail in the NE eyewall ...
Normally, instability in the eyewall is generally very weak with consistent cloud-cover and updrafts not strong enough to support convection that's capable of producing lightning or hail ...

This is looking more and more like yet another RIC (rapid intensification cycle) might be ready to unfold ... until we get to the next ERC (eyewall replacement cycle) ...

Thank you all for this information. I appreciate it very much soo...

josh...time for your meds..

noone was screaming (caps)...i was emphasizing how cold the cloud tops of Ivan are right now.....

i also further explained what i meant later.....

as for your question...the CDO is AROUND (not screaming) the warm core....not over it..

Oh, and also the -80ºC are coming from the cloud tops as imaged on IR ... which IR simply measures (heat, or lack thereof) temperatures within clouds, ground, ocean, etc ...

You can also think about it like this. Summer thunderstorms in midwest sometimes have hail right. they are over hot ground. same type of idea.
I think.

the stronger thunderstorms reach higher levels in the atmosphere, thus the reason for the colder cloud tops.

WARMER cloud tops are associated w/ weaker and low topped convection.
