Quasi-biennial variations of the total solar flux: their manifestation in variations of the stratospheric wind and velocity of the earth rotation

The analysis of regular measuring the Sun full radiation flux I by Nimbus-7 and other space vehicles allowed to obtain a detailed notion on variations of this flux. In particular, quasi-biennial variations (QB Vs) of the values (monthly average value I) and s I (standard deviation I within a monthly interval) were discovered. It is interesting that the QB Vs sI almost coincide in form with the QBVs of many indices of solar activity (SA) and the ionosphere, and the QBVs are almost in antiphase to the sI variations. At present, manifestation of the QBVs in some processes on the Earth was revealed. There was established the relation between the sun radiation QBVs (after «Nimbus-7» and ACRIM-2) and the QBVs of zonal stratospheric wind near the equator, and also the QBVs of the Earth rotation velocity. There is an impression that many of the considered QBV-processes on the Earth are related to the variations of the Sun's radiation full flux.
