Comments on “Simulation of hurricane-type vortices in a general circulation model”

Abstract

In a recent paper, Bengtsson et al. (1982) (hereafter referred to as 882) describe intense tropical vortices which appear in the operational ten-day forecasts of the ECMWF global primitive equation model. This note takes up their invitation for further discussion. Below a number of the major differences between the model and real cyclones are documented in the hope of adding insight on the relevance of their simulations to tropical cyclones in the real atmosphere.
