Description: Recorded climatological data are avail able in several forms. Several publications present data arranged in models for specific field operations (Rutledge and Russell 1971 Van Die and Brown 1974 a,b) Frisby and Peterson 1968). Others provide recorded data in general forms for rainfall, temperature, evaporation, winds, etc. (Environmental Canada Monthly Bulletins, for example). Some publications suggest various techniques for determining probabilities of dry and wet days verified by local recorded data (Feyerherm et al. 1966 Eichmeier and Baten 1962). A dry or a wet day as a single criterion for field operations perhaps oversimplifies the real conditions in the field. For most of the cases, some additional factors affect, and are thus involved in, the decision of whether or not to operate in a particular field. Unfortunately, accurate relations are generally not available for describing the effects of these factors on a given field operation to be executed. Thus, knowledge of the probabilities of dry and wet days, per se, might be of help only as a necessary, but not as a sufficient, condition for decision-making.
