The current temperature variations around the country seem to illustrate the
considerable differences from place to place in certain weather conditions .
Today for instance my temp goes up and down with every passing cloud ,as my
screen is on a south facing slope which before the trees come into leaf gets
a good cooking at this time of the year .
At George Booths Epping site about 6 miles north of here ,his 1140z temp was
3.7c whilst mine 5.6c !,which I think raises several questions about the
validity of record breaking events throughout the years.
The 2003 August 10th heatwave record seemed to be dependent on which side of
a hedge the screen was positioned,and I noticed that day a variation im my
garden of nearly 3 degrees dependent of where my thermometers were placed.
As there are millions of variations as to where thermometers can be placed
( excluding the obvious rude ones) perhaps we can take some records with a
large pinch of salt ??.
Stephen Burt of COL and Philip Eden have done some work on this I think so I
would not be so presumptious as to question their findings of course .

I think this is true to an extent but surely any official records come
from those that have standard exposures, i.e no bushes, trees, water
nearby and a standard height and surface. I do believe however that
different sites close by even meeting the requirements would have
variations - but then what else can you do?

My maxima, when the sun is shining (ho, ho), are always higher than I
might expect. This was discussed here some years ago and I think Philip
Eden suggested that this was due to the West of Scotland Walled Garden
Effect. We overlook Loch Long which means that we're near the bottom of
a trench. The theory was that this trapped the warm air, similar to the
air in a walled garden, which gave rise to these elevated temperatures.

The maximum I recorded last week was 9.3°C in bright sunshine and an
average wind speed of 4 mph. This was three or four degrees higher than
that recorded at Glasgow Bishopton.

As you say much research had already been done on this, notably the
Brogdale record warmth. Every reading is unique to where it was recorded
and reflects the micro climate at that particular place. I made
recordings, in a screen, during the 62/63 winter. The screen was not on
a stand so the low temperatures, however impressive, were of limited
value. In my current setting I suspect temperatures are, if anything,
slightly on the warm side. Differences between our readings, well we've
got similar instrumentation but 100' higher altitude here and 20 yards
from open countryside. The ground is cold and the last of the snow cover
only cleared yesterday.
From time to time I see weather station setups in my travels. The
majority suggest that they have been sited as well as they could under
the circumstances. I've also come across units, particularly VP2, at the
top of chimneys, TBR and all. I belong to CWOP and this is quite a
common practice in the US.
If you look at the UKMO WOW site the majority the amateur weather
stations are currently showing with +/- 2° of each other but there are
some which are way off, one can only speculate as to the set up there.
On a similar theme I recently compiled a list of annual rainfall totals
for the Epping area back to 1860. I used my own figures back to the
1970's but the rest of the data came from the books of the British
Rainfall Organisation. In this case there is no one weather station
which recorded over this period although all credit to the Nicholl and
Hart families who clocked up a century of readings between them. I ended
up with a lot of data which I plan to put on the website. However it's
the variation in annual totals between different sites within the 3
miles radius which was a bit of a surprise. Again, a variety of factors
possible here.
So, as you say, a pinch of salt is required.

Blimey Ron

I googled micro, images and got this (%^&*), pages of it. It's rather warrm, event sultry to say the least. Phew!!!

I won't link it as I don't want to be responsible for what you'll see. Be it your fingers on the mouse buttons.

Very hot micro climate though.

A certain T Squires ,chemist of Epping,kept a diligent rainfall record
between January 1822 to at least December 1844,albeit with a gauge sited 6
feet above the ground. Whilst no direct comparisons can be added to your
post 1860 figures they would surely give a very good indication of the wet
and dry years which presumably is what you wish to convey

All the Epping rainfall records have been produced with diligence Ron.
Yes 1822-1844 would be a useful extension to the record which can be
seen here
http://homepage.ntlworld.com/gesc_b/...es/EppRain.htm
Once I get some time I'll transfer the detailed spreadsheets to the
website. Interesting to see with the passage of time just who the
observers were beginning with Henry Doubleday, the lepidopterist, who
has a blue plaque, through the ladies and gentlemen of several local
families and on to post WW2 when it was the turn of sewage works and
pumping stations to record rainfall.

Doubleday has a short Wikipedia article

http://en.wikipedia.org/wiki/Henry_Doubleday_(1808-1875)

but it doesn't mention his meteorology. If you'd be willing to write a
sentence or two about it, preferably with a supporting reference, then
I'd be happy to add it to the article.
