Abstract
The dynamics of the surface air layer in the Northern hemisphere is studied by the method of allocation of structures with the use of the air pressure field. The spatial distribution of the fields of monthly average values of pressure in the Northern hemisphere is found and mapped; their dynamics is estimated in the period 1955-2000. The pressure field class distribution maps have been built over the Northern hemisphere and the typical fields were found.
