Abstract

North Pacific summer HIGH pressure areas provide smooth seas which allow enhanced 7MHz JA-CA propagation due to specular reflections of RF waves from the ocean surface. I analyzed all the available relevant meteorological and RF data from 2010 to 2021 which demonstrated the presence of the HIGHs, and signal enhancement on July days with surface wave heights of 1m-2m or less, with a Kp Index below 1.7.
