Quasi-lagrangian diagnostics applied to an extratropical explosive cyclogenesis in the north Pacific.

Abstract

A case of explosive extratropical cyclogenesis in the North Pacific is analyzed employing quasi-Lagrangian diagnostic techniques in isobaric coordinates. The First GARP Global Experiment (FGGE) Level Ill-b data set from the European Center for Medium-range Weather Forecasting (ECMWF) is used in a synoptic investigation and mass and vorticity budget diagnostic evaluation of storm development.
