Analyses of the statistical structure of long-term variations in the height- and time-dependent fields of atmospheric pressure and density from rocket sounding data

Empirical models are developed for long-term trends and quasi-periodic vari ations in atmospheric pressure and density at altitudes of 0 to 72 km in th e period 1969-1993. The models are developed on the basis of the regression analysis and analytical representation of spatiotemporal meteorological fi elds inferred from the data of four stations of rocket and accompanying aer ological sounding.
