SOLAR RADIOFLUX AND UPPER-ATMOSPHERE TEMPERATURE,
Abstract
A general analysis of solar radiofluxes between 1,000 Mc/s and 10,000 Mc/s has been made for an entire solar cycle. It is shown that a correla tion between a solar radioflux index and the temperature of the thermopause can be found in the range of 8 cm - 10 cm if its basic component is associated with a 27-day mean value. A linear correlation is found between the 27-day mean value of the 8 cm radioflux and the thermo pause temperature. However, there is a depar ture from linearity at 10.7 cm for fluxes of less than 150 units. The oscillation during a so called 27-day period has a value which is about 50 percent of that of bomponent. It is shown that no corpuscular effect is needed in addition to the normal heating of the thermo sphere by ultraviolet radiation. A table is given to deduce the relationships between radio fluxes at 8 cm and 10 cm and average night-time and daytime temperatures. Finally, the maximum, mean and minimum temperatures have been deduced for night-time and daytime conditions between 1952 to 1962. (Author)
