The Influence of Autumn Eurasian Snow Cover on the Atmospheric Dynamics Anomalies During the Next Winter in INMCM5 Model Data

The influence of autumn Eurasian snow cover on the atmospheric dynamics anomalies during following winter is studied based INM RAS climate model data. North Atlantic Oscillation leading pattern that causes weather and variability in Northern hemisphere. We evaluate up-to-date version (INMCM5) ability – NAO teleconnection simulation different timescales. Maximum covariance analysis (MCA) used to find signals are significantly correlated with anomalies. Using MCA we conclude Autumn present INMCM5 experiments pre-industrial present-day simulation. However, this method fails show phenomenon a seasonal timescale. conduct additional timescale assess sensitivity index predictability initial perturbations. These demonstrate absence direct impact index.
