 Abstract: West European summer temperature has increased at a higher rate than the global mean, and this increase is not reproduced by most last generation climate models. Previous studies suggest that this discrepancy originates from a bad representation of the summer atmospheric dynamics. In this study, a simple algorithm is used to count deep depressions in the North Atlantic summer. A strong increasing trend in deep cyclonic depressions is found in reanalysed data, most notably in the eastern Atlantic region off the continental European coasts. It is suggested that this increase is contributing in a maesurable way to continental Europe temperature increase. A sample of CIMP6 climate is used to show that this trend is absent in historical simulations. The dynamical framework accompayining the deep depression events is also described.
