Weather Review - March 2000

Aircraft contrails fill the sky over Royston on 21st March 2000 (photograph taken at 0818 GMT looking SSW from Burloes). The temperature is 9°C, with a light 2 knot breeze from the SSE, gusting to 6 knots. As in the first picture, the impression is given of a lot of aircraft activity over the Royston area on 21st March 2000. This photograph was taken from a point some 2.5 km east of Royston looking westwards at 0829 GMT. Rapidly growing cumulus clouds in the morning (with this one showing signs of vigorous vertical development) give an indication of showers to come later (and they did!). This photograph was taken at 1004 GMT on 25th March 2000 from the Burloes Estate looking SW. A SSW wind of strength 6 knots (gusting to 14 knots) is blowing, and the temperature is 10.2°C. The communications mast at RAF Barkway is a familiar landmark in the Royston area as it stands at some 160 metres above sea-level on the crest of the East Anglian Heights about 6 km to the south of the town. Although the temperature is 7°C at Royston (Iceni) Weather Station about 80 metres below this point, it is obviously not as high at the mast as a snow shower occurred just before this picture was taken at 1535 GMT.
