Hi all,
Two very interesting ascents from 11Z today are shown below with a few
noteworthy features.

The Herstmonceux ascent shows the surface inversion starting at 975hPa
(MS0.1degC) and ending at 955hPa (8.6degC). The Watnall ascent shows the
boundary layer to be deeper with the inversion starting at 933hPa
(MS3.3degC) and ending at 889hPa (7.0degC).

(11Z Herstmonceux)

In addition, the surface wind at Herst. is de-coupled with the flow above
the inversion, a veer of approximately 90deg. This is not so at Watnall.

With the Watnall ascent you would expect more convective
overturning/turbulence to take place and hence more breaks in the StSc
sheet, but observations from the area show nothing different from those to
the SE. I'm lost, please help !

Thanks, Joe
