Cavendish, Suffolk

Altitude 55 metres

Someone’s back garden (*), not a problem, neither is being a very hot day unless the results are conflated out of context, which they are.
(* unless I have made a mistake)

“The highest known temperature recorded in the area was 37.3 °C at Cavendish on 10 August 2003 and…” — exact source will me mentioned in the next article, is the Met Office.


Image from 2003.

Estimated Class 4/5, examine time images, shadows, very poor exposure and unstable, is a working garden. Cropped field close bare some of the year.

UHI, local site, distance, semi-rural.

Note please: this site will be owned and operated by a private individual, a volunteer who has done this year in and year out, within the land space that he has. Keep any criticism for the Met Office and professionals who fail to make the nature of sites they use very clear.

The true extent of the time series is unclear. Climatic data is claimed from 1974 but notes point to some uncertainty on whether it was this station, what has altered. During 2010 it turned into an hourly reporting AWS.
I suspect this station is conflated with another, mentioning 1961.

If all this is made crystal clear to anyone using the data it has value, otherwise apples and oranges.

    Yep you’ve got it Tim.

    I thought I could see a wind mast from this Google street view.

    I’d like to point out that a newly plowed field has similar properties to equivalent expanses of tarmac or concrete.

    “Question: What factors determine moderate thermal development, release, rate of ascent, and decay?

    Development – The surface areas that produce thermals best are parking lots, ploughed fields, dried grass areas or bare rocks (to mention but a few).”

    Yes, spot on mwhite.

    Some time ago to do with a different context someone pointed out the balloonists too are very aware of the complex world in lower atmosphere. This was primarily waking people up to the low level nocturnal jet.

    One thing which does seem the case is record daytime highs tends to be associated with specific detail weather conditions. I think there is more in this, would be very useful to try and unravel what goes on and why bad meteorological stations pick this up, perhaps thermal shift, detaching, there is a sudden change in wind generally and I think unusual higher atmosphere conditions, strong inversion. I’ve casually spotted three of these cases so far without going examining each case.
