Abstract: Equations are developed for obtaining mean monthly degree days above any base from mean monthly temperature and standard deviation of monthly average temperature. By the use of data for all months for twelve widely scattered ...

Abstract: For later development of design snow loads, the water equivalent of snow on the ground appears to be the best meteorological variable for determining design values. The appropriate climatological series for this is the ...

Abstract: The general properties of the gamma distribution, which has several applications in meteorology, are discussed. A short review of the general properties of good statistical estimators is given. This is applied to the gamma ...

Abstract: Approximate convolution methods are developed for unmixed and mixed precipitation distributions. Results of applying these to monthly distributions to obtain the distributions of sums of various numbers of months are ...

Abstract: It is shown that the freeze distribution is a mixture of the distribution of freeze-date and the simple dichotomous distribution of freeze and freezeless years. This is applied both nonparametrically and assuming a normal ...

Abstract: Methods and charts are presented for estimating seasonal degree-day probabilities and quantiles for any location in the United States. Confidence limits for these are given enabling the engineer to judge the accuracy of ...

Abstract: The probability function of degree days below the base 65° F. is derived from the temperature probability function. Standard statistical analysis is applied to this function to obtain the relationship between mean degree ...

Abstract: Heating engineers sometimes have need for normal degree days for bases other than 65° F. Further analysis of the relationship between mean temperature and mean degree days for base 65° F. showed that the form of this ...

Abstract: Following previous work, climatological statistics and computational methods are presented for obtaining the quantiles of first one-inch 24-hour snowfall. These are employed in computing the .05, .10, .30, .90 quantiles ...
