LINKS BETWEEN ATMOSPHERIC CIRCULATION AND SURFACE AIR TEMPERATURE IN REGIONAL CLIMATE MODELS

Popis výsledku v původním jazyce

The study examines links between atmospheric circulation, represented by circulation indices (flow direction, strength and vorticity; derived from gridded mean sea level pressure), and daily maximum (Tmax) and minimum (Tmin) air temperatures in regionalclimate models (RCMs) over Central Europe. We make use of RCM simulations with high resolution carried out within project ENSEMBLES, over the control period 1961-1990. The aims of the work are (i) to identify errors in RCM-simulated distributions of circulation indices in individual seasons, (ii) to identify errors in simulated Tmax and Tmin under particular circulation types, and (iii) to compare the performance of the individual RCMs and the dependence of the results on the driving global climate model. It is shown that most of the RCMs qualitatively reproduce the observed distributions of the airflow indices and the general relationships between the circulation indices and anomalies of near-surface temperature reasonably well.
