Investigation of boreal storm tracks in historical simulations of INM CM5 and reanalysis data
Abstract Ensemble simulations of the 5 th version of the INM coupled climate model are employed to analyze the Northern Hemisphere storm track characteristics in the winter season.

Summary: | Abstract Ensemble simulations of the 5 th version of the INM coupled climate model are employed to analyze the Northern Hemisphere storm track characteristics in the winter season. The results show similar features of the North Atlantic and North Pacific storm tracks that dominate in the Northern Hemisphere in the model simulations and reanalysis data. A composite analysis of the weakening/strengthening of Arctic stratospheric polar vortex events with their influence on the troposphere shows an equatorward/poleward shift in the North Atlantic storm track. As a response to the recent Arctic amplification, a poleward shift in the Pacific storm track and weakening of the North Atlantic storm track have been revealed when comparing two periods: 1998-2014 and 1980-1997. |
