| This early morning cloud study was viewed on 19th October 2008 at 0750 GMT between Royston and Barley. Two contrails clearly stand out from the cloud whilst what appears to be the shadow of a third contrail can be seen to the left of and parallel to the the right hand contrail. Royston is under the influence of large anticyclone centred over SE Europe whilst a deep depression is moving east between Iceland and Scotland increasingly tightening the pressure gradient and consequently strengthening the wind. At the time the photograph was taken a SW wind of 6 knots gusting to 12 knots is in evidence in a temperature of 8.1°C. Sunshine for the day was restricted to 2.6 hours. | A tranquil scene on the Wimpole estate in Cambridgeshire some 10 km N of Royston, at 1209 GMT on 21st October 2008. The cattle seen in this photograph belong to the largest rare breeds centre in East Anglia which is located at Wimpole. Just discernible in the distance is the 1774 built Gothic Tower on Johnson's Hill whilst out of view in the valley in between is the lake and Chinese Bridge. A keen westerly wind is sweeping across the estate and at this time the wind speed at Royston was measured as 10 knots gusting to 24 knots in a temperature of 12.2°C. The cloud seen in the picture has built up quickly after a sunny morning in essentially clear skies. Sunshine for the day was 8.9 hours. | This Autumn has produced an abundance of leaf colours, and the sycamore trees in this plantation on the Burloes estate to the SE of Royston (as seen at 0958 GMT on 27th October 2008) are providing a spectacular display in the morning sunshine. This plantation was set in the early 1970's adjacent to a mature wood (which was all but destroyed in the great gale of 16th October 1987 and has since been re-planted). It is hard to believe that only the next day, 28th, Royston experience its first snowfall in October since records began at Royston (Iceni) Weather Station in 1972, and the temperature plunged to its lowest level since 29th October 1997! The temperature at this time was 6.9°C and daily sunshine was 7.3 hours. |
