Abstract: Many studies of the joint frequency of the initial and final conditions of weather elements such as cloud cover, visibility, rainfall or temperature attest to the importance of the initial event as a predictor of the later ...

Abstract: The map is proposed for worldwide climatological statistics, to depict accurately the area covered by some specified meteorological condition or element. Since it is square, a grid overlay divides the map into small squares, ...

Abstract: In recognition of the fact that a weather forecast is rarely 100 per cent accurate, this paper considers the value of figures for the probability of a meteorological event in meeting specified operational requirements. An ...

Abstract: If an operation is influenced by the weather, each course of action should result in a profit, cost, or loss depending upon the subsequent development or state of the weather. To delve into the problem of relating the ...

Abstract: Single-station climatic probability of a meteorological condition can be estimated from a set of observations taken at the station. The probability, however, of the same condition prevailing along a line of sight or line ...

Abstract: The article is limited to consideration of a forecasting program in which a forecaster chooses as his forecast one event out of a finite group of well-defined, mutually exclusive events, for example, ?rain? or ?no rain.? ...

Abstract: Previous models for estimating the conditional probability of an event have used, as the condition, an initial categorized event such as no rain or overcast at time zero. But initial conditions frequently are observed and ...
