Paper Abstract

Estimates of the tropospheric lapse rate γ and an analysis of its connection with the surface air temperature Ts in high latitudes of the Northern Hemisphere for summer and winter are performed using monthly-mean data from the ERAInterim reanalysis (1979-2014). According to the reanalysis data the lapse rate values increase from 4.7 K/km near the pole to 5.3 K/km in subpolar latitudes in winter and from 5.3 to 6.1 K/km in summer. The estimates of dγ/dTs in interannual variability are found positive over the most part of the Arctic from reanalysis data. At the same time, a negative correlation between γ and Ts was found for the Atlantic sector of the Arctic in winter and for the central Arctic in summer. It is also noted regional peculiarities in the connection of lapse rate with Arctic oscillation for winter and summer.
