Windrush Weather

Light cloud and partial eclipse limited solar activity in the morning

The research that Lincoln University had requested, via my national meteorological organisation linked to the Met Office, concerned the partial eclipse. For this I recorded the data very 10 minutes from 00.00 on Saturday up to 09.30, then every minute until 12.30, lastly back to ten minute interval until 20.00, supplying five items of meteorological data at each time interval. During the period of the eclipse there was variable cloud that gave variable solar radiation data but noticeable was that the air temperature was very stable, with minimal variation of 11.1C or 11.2 between the lengthy period of over an hour between 10.16 and 11.25, even though the sun was shining brightly. Over that period the solar radiation varied from 603W/m2 to 339W/m2 at the time of the greatest coverage of the sun by the moon. The thermometer eventually gave a maximum of 13.3C at 15.25 that was a little depressed as after the eclipse had ended there was a significant increase in wind speed. The data was limited to those with professional equipment that was naturally aspirated and radiation shielded also sited away from buildings and hard surfaces.

The minimum overnight was a low of 6.8C at 07.22 early Sunday morning.

The earlier start on Sunday, due to the clocks changing, meant that the sun did not get to work on the air temperature until after around 07.30 with a temperature of 8.1C at 08.00.

We are fully under the control of the high pressure that has been easing in from around the Bay of Biscay yesterday, to move slowly eastwards across the UK. As it relocated overnight the wind veered from southwest yesterday to northwest for much of Sunday. The air stream is moving clockwise around the anticyclone, as it does, thus the change in word direction, the low pressure now well to the east.

This anticyclone is forecast to greatly influence our weather for the next few days as it settles around the UK.

The images appearing over these days were taken by me for the Marlborough in Bloom portfolio and presentation in 2015 when we won gold.
