Extended experience in the construction and use of | |
several different predictive nomographs covering a wide | |
range of frequency distributions of various types of | |
weather and other phenomena, suggested the probability | |
that a universal series of patterns of frequency | |
distributions might permeate the whole of nature. This | |
study is based in part on the several nomographic | |
patterns developed in previous studies. It assumes that | |
all of the frequency distributions we are likely to | |
encounter in practical climatology, whether symmetrical | |
or asymmetrical (skewed), may be fairly well approximated | |
by a family of cumulative frequency curves, provided they | |
are plotted on such a scale that 100 units represents the | |
whole range of observational experience in each. The | |
predictive patterns in the General Nomograph and its | |
associated table depend for their operation on the | |
numerical position of the mean (average) between the two | |
extremes (maximum and minimum) in the frequency | |
distribution, when the three related measures are reduced | |
to a 100-unit scale. The means of frequency distributions | |
having various degrees of skewness lie along a diagonal | |
line from the lower left to the upper right of the basic | |
section of the nomograph. Other lines (curved) trace the | |
values of other percentile or fractional parts of the | |
various distributions. The construction, use and | |
reliability of this nomograph and its associated table | |
are given in this report. | |
