Temperatures in the summer of 2017 in the UK crashed on the 20th of July and have never recovered in the almost three weeks since it’s been since then. You can see clearly how the temperature has almost flat lined in the NCEP reanalysis data for the grid point 52.5° north and 2.5° west (just to the west of Birmingham), with almost all the 6 hour anomalies negative since then, negative (fig 1). I remarked in a blog only yesterday about how unusually flat the daily CET values had been since the 20th of July. Its probably all tied up with that ‘ribbon of high wind speed high in the atmosphere‘ that we like to call the jet stream.
Meanwhile in stark contrast to the UK, just to the northeast of Rome in Italy, at the 42.5° north 12.5° east grid point, things have been slightly different. A part from three short cold spells, the temperature anomalies there have all been well above average since early June (and before), with the recent heatwave this month clearly evident.
I get the distinct impression from the recent news from the Met Office that they are trying to convince us that summer 2017 is not a complete wash out, well not yet anyway. Perhaps they have been urged to say that by a phone call from the Director of VisitEngland, Andrew Stokes (fig 1). As far as I can see, there was some lovely weather about in May and June of this year, but things went downhill in the first week of July, and at the moment don’t look like they want to improve, blame it on being the wrong side of the jet.
VisitEngland and the tourist boards around the UK, must know that the weather forecast has a tremendous part to play in motivating holidaymakers to get out and visit the various attractions around the country, so it’s no wonder that tourism looks to the Met Office to ‘gee’ things up in the weather forecast, especially now that the school holidays are here. I personally would rather hear it as it, than be coaxed into believing by weather presenters, headlines and news articles, that the summer up till now (and for the foreseeable future) is anything other than average.
