QUEST PRESSED FOR BETTER CIVIL AVIATION WEATHER FORECASTING

The article briefly describes forecasting methods for both airport forecasts and aircraft route forecasts developed by the USSR Hydrometeorological Service. Among the airport forecasting methods discussed: regression equations to predict cloud heights of 300 meters or less, using a semi-empirical monograph to predict minimum visibility in fog, predicting wind velocity from wind measurements over the preceding 1-3 hours by correcting for changes in the pressure gradient at the surface and the diurnal variation in wind velocity in the atmospheric boundary layer, using changes in air temperature and air pressure to predict squalls, and the prediction of thunderstorms by calculations involving the height of the cumulonimbus cloud tops, the thickness of the layer between the 0 deg C level and the cumulonimbus cloud tops and the temperature at the tops of the clouds. The article also describes a computerized system which uses numerical forecasts of winds and temperatures at altitudes between 6 and 12 km are used to prepare automated preliminary flight plans.
