I think the loss of DP and the better mixing are, together, putting back temp - ...
I'm also curious about something else... More scientific, but I'm not sure -
The surface obs seem to average 220 to 260 with the winds... But the CU field is more like 280 or even 290... The latter is a subtle d-slope direction for most, but the former,... is not.
Does that mean the we do not benefit from d-slope compression... I'm not sure it doesn't. Because I can reason that "at the 900 mb sigma level" there is compression from over top... Then, indirectly, we mix that with the boundary layer tumble -
