The influence of lower atmosphere dynamics on the mid-latitude sporadic E-layer

Abstract

The relationship between the occurrence of intense sporadic-E layers and features of tropospheric weather has been investigated. It has been found that, as certain features of the tropospheric pressure field (as identified from meteorological charts) develop over specific geographic regions, the probability of intense sporadic-E layers increases. Investigating the 500 mb chart has shown that the probability of occurrence of intense sporadic-E layers increases in response to distortion of patterns of zonal westerly flows. © 1997 COSPAR.
