RELATIVE DISTRIBUTION FUNCTION AND METEOROLOGICAL ENTROPY

A new concept, the relative distribution function, is brought up in this paper for the analysis of the distribution of certain variable in a material system. It is demonstrated that the function is equal to the probability density function and several examples of the relative distribution function are given. Because of the known relation between entropy and the probability density function, and the equality between the latter function and the relative distribution function, a method is given to calculate the entropy value of the meteorological element fields.
