Comments On This Entry JH writes: My dreams usually have realistic vorticity production terms, so it's good to hear about one that doesn't. MR writes: Most of us dream about weather, but only Mark Branson would analyze the weather in-dream to the extent of assessing convective precip in non-convective cloud systems. CR writes:
I had a dream I was eating grapefruit-sized hail, and when I woke up, my
updraft was gone.
Duff the Dust Devil writes:
Most of my dreams are about getting stretched out too much-sometimes I also
dream I move into subsiding, irrotational flow, but I quickly wake up before that happens.
Usually that happens right when I'm first falling asleep though.
JH writes: Looking back at the comments page for Mark Branson's entry, I erred... for some reason I was thinking that Mark's dream of giant hailstones involved a giant tornado as well (wishful thinking, I'm certain), thus my comment about a "realistic vorticity production term." I was about to retract this comment. However on second thought I will stand by it and defend it. Mesoscale rotation is associated with an enhancement in the vertical perturbation pressure gradient, and a larger gradient will enhance updraft strength and thus contribute to the growth of larger hailstones. Such rotation and associated pressure gradients are unlikely to be associated with a stratus deck, so I maintain the importance of the vorticity production term in this dream. |
