Abstract:

This paper presents an objective aid for the forecasting of noontime visibility at Chelveston during the winter. Use of this forecasting aid will by no means solve all of the forecasters problems, but it will support his predictions with the best available data and should consequently improve not only his accuracy but his confidence as well. From data available at 0700Z, forecast the occurrence of visibility less than one mile at 1200Z at Chelveston in winter is the problem under study. Previous studies have shown that the most reliable predictor in the United Kingdom is one which considers the measurement of the low level wind flow. It was decided to use the 0700Z surface wind speed Knots and direction magnetic-36 points at Chelveston to measure the low level flow. Author
