Another interlude gives me space to update the novel statistics computed from published data. This is not comparable with the official methods, it’s better. Takes into account normal variation during a year; bends the data to near gaussian.
May was not particularly interesting, June was the 2nd dimmest for S and SE England since these records commenced 1929.
Rainfall across the UK regions was normal for the month.
Sunshine in most cases half to one standard deviation above average.
Temperature, Tmin, Tmean, Tmax were all slightly below normal, in a few cases by nearly 1 SD, but mostly only slightly.
This seems a peculiar result given April 2016 was lauded as dreadfully cold… at least all I’d gleaned from a hospital bed. Not so according to these figures.
More peculiar still is the contrast with the Met Office article published near the end of April. This differs sharply in one parameter: sunshine, below average. Maybe this is illuminating?
A little warmer than normal.
Precipitation was normal for the north-west including northern Ireland. To the east it was wet, most regions by 1 to 2 SD.
A surprise was sunshine. To the south and east mostly 2 to 3 SD below normal, dim it was.
A curiosity is the exceptionally low sunshine records being set mostly during early summer… such as June. This implies an episodic exceptional weather type, in 2016 there was wet air arriving from continental Europe producing many thunder storms.
This largely agrees with the Met Office blog article.
