Paper Abstract

The paper assesses the spatial and temporal variability of dangerous meteorological phenomena associated with wind, precipitation, thunderstorms, extreme temperatures in the Tomsk region. Observational and ERA-Interim reanalysis data with spatial resolution of 0.125°x0.125° over the period 1979-2017 were used. The characteristics of atmospheric circulation were also calculated, including the indices of global circulation and convective instability — CAPE and LIFT ones. In order to determine the prevailing mechanism in the formation of dangerous meteorological phenomena, an assessment of the degree of their relationship with the circulation characteristics was obtained
