Inland areas of Grampian and the Moray coast seem to have collected a disproportionate amount of rain during the last week. Both Kinloss and Lossiemouth are reporting weekly totals well over 40 mm, whilst Tain just a few miles to the northwest and the other side of the firth, have received little more than 10 mm. It’s hard to put all this down to the rain shadow effect of the northwest highlands because rainfall totals from Wick and Altnaharra with little shelter are also much lower than further south. The gauge on the river Findhorn shows just how water levels...
Here are this year’s extremes for air temperature, sunshine and rainfall I’ve extracted from the SYNOP data that I download courtesy of the OGIMET site. I forgot I had written this application so this post is as much as a reminder to me to use it every now and again! I could bemoan the fact that the Met Office refuse to release all the climate station data they have, which is why the sunshine coverage is sparser than it need be, but in the spirit of the new look xmetman website I’m just going to thank them for releasing what...
The spell of below average precipitation continues across the whole of the UK with eastern regions worst affected. The data I am using is the latest daily UKP regional gridded data which I download from the Met Office. Three regions are reporting less than 80% of the LTA, with Central and eastern England having the lowest anomalies of just 77.4% of the 1981-2010 LTA. It’s now been over five years since any month in England and Wales recorded an anomaly of 200% or higher.
I imagine that today’s showers have added several inches more to the existing cover above 2,500 feet on Ben Wyvis.
It’s no wonder that the weather in eastern parts of the UK was so dry during April 2019. A positive anomaly of 10 hPa just to the west of Norway and a negative anomaly of 7 hPa just to the southeast of Cape Farewell in the south of Greenland produced a negative zonal flow across most of central and northern Europe.
A noticeable dry spell that started towards the end of 2016 across eastern parts of Scotland. Having said that the overall trend in the last twenty years has changed very little.
