\begin{abstract}
To understand the causes of climate change, it is necessary to consider
the relationship between the various physical fields of our planet. The
relationship between variations in atmospheric circulation and the
magnetic field has received little attention.We studied changes of
atmospheric circulation in the lower troposphere and geomagnetic field
in the Northern Hemisphere during the 20th and beginning of the 21th
centuries to determine spatial-temporal relations between variations of
these fields . Integral characteristics of atmospheric circulation and
geomagnetic field have been investigated in the latitudinal band 40-70o
N , applying the same approach. In the indicated latitudinal range, the
main centers of action of the atmosphere in the Northern Hemisphere are
located (Canadian and Siberian anticyclones, North Atlantic ridge, and
Icelandic and Aleutian depressions and European trough), as well as
global geomagnetic anomalies (Canadian and Siberian). For the analyzed
time period there is the most complete set of observational data, which
ensures high reliability of the results obtained. The time diagrams were
plotted for atmospheric circulation and magnetic field by their integral
characteristics. Their comparison showed that the minima and maxima of
the pressure field and the full vector of the geomagnetic field coincide
quite well. This allows to assume that trends in changes in the
geomagnetic field and atmospheric circulation, which were outlined at
the beginning of this millennium, will continue in the coming decades.
For prediction of global changes of the air pressure and geomagnetic
fields in the future it is possible using the same methodology.%
