Explosive East Coast cyclogenesis over the west-central North Atlantic Ocean: a composite study derived from ECMWF operational analyses

Abstract

The evolution and structure of the composite bomb is diagnosed using a moving coordinate system consisting of a box with dimensions of 35° x 35° of latitude-longitude. The results reveal that explosive cyclogenesis is a baroclinic phenomenon in which the rapid development in the presence of strong upper tropospheric forcing is most likely enhanced by a highly destabilized lower troposphere. Additionally, the composite analyses of the bomb show a considerable amount of detail considering the horizontal and vertical resolution of the ECMWF data. -from Author
