| Colourful sunsets have been infrequent in recent months and this one as seen from Royston at 1909 GMT on 11th August 2012 is rather subdued with little colour but nonetheless worthy of photographic capture. Up to this point in August the month had been dry and sunny although temperatures were lagging slightly below average. For the period 1st to 11th sunshine of 74.0 hours was 18% above average for this period, whilst rainfall was only 39% of average at 8.7 millimetres. Sunshine on 11th was 8.6 hours, following 13.6 hours on 10th, this likely to be the sunniest day of the month. At the time of this photograph an ENE breeze of mean speed 2 knots gusting to 4 knots was drifting across Royston in a temperature of 17.2°C. A maximum temperature of 23.7°C had been achieved earlier in the day (at 1155 GMT and 1325 GMT), this being 0.7°C above the average for 11th. The synoptic chart shows East Anglia under the influence of an anticyclone over Scandinavia at this time, whilst a band of showery rain is edging slowly north-eastwards over the south-west peninsula. | The wide expanse of arable land situated between the A505 and B1139 roads some 2.5 km E of Royston is featured in this view as seen (at 0729 GMT on 12th August 2012) from the B1139 mid-way between Royston and Barley. The A505 runs along the first line of trees in the middle distance whilst beyond is the ridge of higher ground running between Hyde Hill and Goffers Knoll. The harvest is underway and here the oilseed rape is being tackled first and as can be seen partially completed, with the wheat nearer to the camera waiting its turn. Conditions for harvesting are good at this time as this day had been preceded by 4 completely dry days. At the time the photograph was taken an ESE breeze of mean speed 1 knot gusting to 6 knots was providing early morning ventilation for drying the crops, in a temperature of 16.4°C and relative humidity of 90%, which reduced to a minimum of 47% at 1235 GMT. The maximum temperature for the day was 25.8°C, registered at 1315 GMT, and accumulated sunshine amounted to 9.3 hours by the end of the day. | This familiar landmark in the Royston area is the entrance to the stable block at Wimpole Hall (10 km N of Royston) as seen at 1358 GMT on 18th August 2012. In about 1842 the 4th Earl of Hardwicke had commissioned H. E. Kendall to design a new and larger stable block to replace the original 1690's stables which were situated nearer to the house. This modified design was then erected in 1852, these stables being a Victorian version of the late Stuart baroque. Today the stables provide welcoming facilities for visitors to the house, gardens, farm and park. This fine display of cirrus clouds has replaced the multiple contrails in the early morning skies over Royston as a cold front edges eastwards but becomes almost stationary over central England whilst on its eastern flank very hot air is being drawn northwards from Spain and France. The effect of this was that a maximum temperature of 31.4°C was experienced on 18th, the hottest day of the year to date (and likely to remain so given that in the 30 year means temperatures now gradually reduce until mid-February!). |
