Comparison of observed and simulated cyclone frequency distribution as determined by an objective method

HERVE LE TREUT, EUGENIA KALNAY

Abstract

We have designed an objective scheme to diagnose the statistics of extratropical cyclones, cyclogenesis and cyclolysis. It uses as much as possible the same criteria which are used for subjective analyses and allows an evaluation of model performance not captured by standard model diagnostics. Examples of possible applications to forecast and simulation experiments are presented in this paper.
