Abstract : Examination of meteorological synoptic analyses in the stratosphere and lower mesosphere and f(min) values observed over North America reveals a significant correlation between the passage of a deep planetary wave and increased electron densities in the lower ionosphere. As evidence of this correlation, a series of synoptic analyses concentrated in the upper stratosphere, along with longitudinal cross sections of zonal winds and temperatures, and profiles of f(min and the zonal, meridional and vertical components of the wind at 40 and 50 km. These calculations show, in general, that the correlation increases with altitude, decreases with an increase in latitude and that the zonal wind in midlatitudes exhibits the highest correlation. Correlation coefficients between f(min) and planetary magnetic indices, solar sunspot number and solar flux would point to exclusion of extraterrestrial parameters as a source of the observed electron increase.
