Conrad: I am interested in learning why a narrow dry band is
sometimes observed to develop aloft (300-500 mb) in satellite
water vapor imagery along dry lines during the late afternoon.
I've observed such 'dry lines aloft' in a couple of cases. I don't
know how common they are. They suggest that significant sinking
and drying aloft may be linked to the PBL circulations (thermal
solenoids you have proposed. It would be interesting to measure
2-d cross sections in their vicinity and to investigate their
possible role in convection initiation/evolution. While it would
be possible to create a separate hypothesis concerning the formation
of 'dry lines aloft', it might be better to leave this as a topic
related to your hypothesis. What do you think?
