WMO03265, Topcliffe

54 12 17N 01 23 24W
Altitude 28 metres

Provisional estimate Class 2 if the matter of dead ground cover can be resolved otherwise Class 4

UHI, barely used local airbase, otherwise none.

Topcliffe seems to be a reserve RAF base used mainly for student/cadet training in prop trainers.

The ground cover problem

Google image shows early season rape fields coming into flower so it is late spring yet here we have a wild difference between grass generally and the rough airfield areas. Moreover close examination suggests scattered material from farm machinery, including in the met enclosure.

If this is recent practice during the year I think that warrants degrade to class 4.

Views, opinions and information welcome.

    It’s a record Breaker.

    “Record Low Temperature
    On the early morning of Friday 3 December 2010, the weather station air temperature was −19 °C (−2 °F), making it the lowest temperature ever recorded in Yorkshire”

    Yep, in the Vale of York, where the cold rolls down off the east Pennine hills and hangs around between them and the north Yorks moors. Frequently mist covered from daybreak, it can be an ice coolbox in winter.

    I can vouch it is perishing up there.

    Usually great lows are wind falls to zero under clear sky with full sky exposure for radiating away over short grass. In this case be interesting to look at the fine detail of what happened.

    Can probably get the full hourly data including wind. (need to finish the software)
