An equation relating temporal changes of relative humidity and temperature: case of variable intervals of time

Abstract

This work is directed to establish how the linear relation h₂ – h₁ = -0,03 - 3,586(T₂ – T₁), which is suppose to be valid at any point on the Earth and time of the year, and whose coefficients are obtained using synchronous series of three hourly data of relative humidity and temperature obtained from observations made in the Meteorological Observatory of Matacán (6, 794 data points), is verified if variable time intervals to establish the relative humidity and temperature variations are considered. To do this, the equation coefficients were recalculated, with the same methodology, using values of the variables which were obtained in the same observatory during the whole year of 1978 (268 data points). The results are compared with the corresponding values of the studied relation and the differences are justified. In function of this results it is possible to infer that the study equation is also valid when the time intervals used to determine the variations of relative humidity and temperature of the air are variable.
