Solar control of geophysical phenomena

An all-union conference on Interrelationship of Meteorological Phenomena and Processes in Circumterrestrial Space was held in Moscow. The purpose was a review of progress in study of different mechanisms of interrelationships of geophysical and meteorological processes and phenomena in the upper atmosphere and in space. The change in the influx of solar radiation to the Earth during the last century was studied. On the basis of data on parameters of the Earth's orbit and brightness of the solar disk they concluded that the influx of solar radiation is decreasing not only due to a change in the brightness of the solar disk, but also due to a change in the parameters of the Earth's orbit with a duration from several years to several decades. Changes in composition and temperature of the ozone layer under the influence of UV radiation and cosmic rays was discussed. Although ozone for the most part is found in the lower and middle stratosphere and solar flares have little effect on its total content, there is good basis for assuming that the ozone mechanism plays a definite role in changes in weather and climate. The role was also studied of the Earth's electrical field in solar-terrestrial relationships, which plays an important role in the propagation of disturbances in the circumterrestrial medium and must be taken into account in studying the process of preparation of earthquakes.
