| Abstract: | The partial reflection technique was used to study h-type Es over Uppsala for three months in 1973. This showed that the phenomenon was most common just after 0600 and before 1800. A statistical study of the occurrence of Es over Uppsala for the solar minimum and solar maximum years 1963 and 1968 confirms this result and shows that this type of Es occurs about twice as often in solar minimum years than in solar maximum years. There is a strong maximum in summer months. The downward movements of Es-h decreases as the height decreases, consistent with the hypothesis that this type of Es is generated by internal gravity waves. |
