Scientific paper

A study is made of the depressions in day time midlatitude F-region electron density under relatively quiet geomagnetic conditions, through a detailed analysis of five specific events, using total electron content data at Auckland and Invercargill and peak density data at Auckland, Christchurch, Campbell Island and several Australasian stations. In peak density, the depressions are noticed to have a latitudinal extent from about 27 to 53 deg with prominent effects at latitudes around 40 deg and with a longitudinal extent of about 3000 km. Based on the complementary experimental results from ionogram analysis and total electron content measurements at Auckland, it is suggested that the depressions studied here, all of which have been noticed to occur in association with auroral disturbances, are due to changes in atmospheric neutral composition brought about by modifications in the global thermospheric circulation pattern following heating in the auroral zone.
