Paper Abstract

We study variations in the vertical temperature profile in central parts of warm and cold sectors of extratropical cyclones which emerge and evolve in the Northern Hemisphere during solar minimum. Dynamics of the vertical temperature profile during cyclogenesis over the land and ocean under quiet and disturbed geomagnetic conditions is analyzed. The classic cyclolysis occur under quiet geomagnetic conditions; the temperature decreases in the warm sector and increases in the cold one at a level up to 300 hPa. Under disturbed geomagnetic conditions, there is a slow increase in temperature in the cold sector. The warm sector of the cyclone is characterized by a small increase and stabilization of temperature, which perhaps results in slow cyclolysis and in increased lifetime of cyclones.
