On the dynamics of a case study of explosive cyclogenesis in the Mediterranean

Abstract

In this study, a case of explosive cyclogenesis over the central Mediterranean is examined with the aid of the MS Cyclone Detection and Tracking Scheme along with the Vertical Tracing Software and the Parcel Trajectory Software that were developed in Melbourne University, employing a regular 0.5° × 0.5° latitude–longitude grid of the ERA-Interim dataset. It is found that the explosive cyclogenesis occurred as a result of the downward intrusion of high-PV cold stratospheric air into the upper troposphere combined with a low-level warm environment surrounded by the bent-back structure of the cold front in the poleward side of a jet streak. The positive effect of the diabatic processes in explo..
