VIRTUAL TOUR OF THE WEATHER STATION

WIND READINGS

The weather station has a number of different anemometers all of which perform slightly different functions. Pictured above left are anemometers for recording current and maximum gust readings. The taller mast supports the wind strength and direction sensor for the automatic weather station together with the electronic sunshine recorder, also feeding to the automatic weather station. The shorter mast supports an anemometer and wind vane which currently is being used for daily observations at 0900 GMT. Since the photograph was taken this mast has been replaced raising the anemometer to the same height as the first. The insert shows the dial to which the instrument is connected in the office. Pictured above right is an anemometer which logs averaged wind speeds over 10 minute intervals and is used primarily to record gales. A stand alone electronic sunshine recorder is located at the foot of the mast - used to determine sunshine totals for the Daily Weather Report.

These anemometers are positioned to achieve maximum exposure to the wind. Pitsford Hall benefits from occupying the highest point on the school site and this affords a good situation from which to monitor wind strength.

Average wind speeds over 24 hours and the 'run of the wind' are determined using a cup-counter anemometer (right). Readings are made from this instrument daily at 0900 GMT. Additionally, there is a standard wind vane used occasionally to establish wind direction during very light breezes when the other vanes may show some inconsistency.
