quasibiennial variations

Dynamics of solar activity and variations of geomagnetic field and It’s ecological distarbence

In the paper the dynamic of solar activity and connected to it the geomagnetic field variations and its ecological disturbance on Ukrainis territory is analyzed. It is shown that solar activity concerning to the cycles with 100–200 years periods is in the state of transition to decreasing. Interconnection of the quasibiennial variations of solar and geomagnetic activities is studied. It is shown that ecological disturbance of geomagnetic field on Ukrainis the Ukrainis territory do not exceed of the quota.
