Relationship of ground-level tropospheric pressure day-to-day variations with geomagnetic characteristics in the North-east of Russia

摘要

We showed that in conditions of the North-east of Russia there are steady connections of changes of monthly average values of ground pressure from with the level of geomagnetic activity. It is connected to a geographical position of the indicated region and arising thereof conditions providing high sensitivity of the state of the lower atmosphere to external influences. In the present work on a basis Cosmophysical observation of "Magadan" observatory and the data of aerologic sounding of an atmosphere of Kolyma UGMS interdayly changes of ground pressure and their connection with the variations of elements of a geomagnetic field are investigated. It was shown, that daily average values of pressure change in connection with the variations of horizontal component of geomagnetic fields. In all seasons reduction of H -component during geomagnetic storms is accompanied by reduction of P with ～3 day delay. It is possible to assume, that the changes of atmospheric circulation at heights ionospheric current system during geomagnetic indignations result in deepening and displacement of cyclones from the water area of the sea of Okhotsk to the researched region.
