Receiver Operating Characteristic Curve Analysis-Based Evaluation of GCMs Concerning Atmospheric Teleconnections

Popis výsledku v původním jazyce

The evaluation of general circulation models (GCM) is a fundamental step in climate research in terms of both quality assurance quality control and realistic representation of the dynamics of the atmospheric flows in the future projections. In this paper, a statistical method is introduced to evaluate GCMs with respect to teleconnection patterns in the winter 500 hPa geopotential height field over the Northern Hemisphere (NH). The procedure uses the combination of negative extrema method and receiver operating characteristic (ROC) curve analysis. The proposed method is demonstrated using selected general circulation models (GCMs) disseminated by the CMIP5 project. The ERA 20C reanalysis was used as a reference, supported by the NCEP NCAR R1 reanalysis. The proposed method enables us to track changes in the geographical positions of the action centers (ACs), therefore, to detect improvement/deterioration in the GCM performance with time. It was found that the majority of the GCMs reproduce prominent t
