Spatial peculiarities of the NAO impact on air temperature and precipitation field in1950-2000
The research analyses spatial peculiarities of the North Atlantic Oscillation (NAO) impact on air temperature and precipitation amount in Lithuania in the context of Europe from 1950 through winter 2000 (December-March). It also discusses the dynamics of NAO-1, NAO-2 and NAO-3 indices, as well as co...
