Are EARS-IASI L2 useful for nowcasting sting jets?


Christian Herold (DWD) investigates the usefulness of IASI L2 products in nowcasting, detecting and analyzing sting jets in rapid cyclogenesis.


Strong winds southwest of the center of a Shapiro-Keyser-Cyclone are often associated with a cold conveyor jet or a sting jet. The sting jet is a strong mesoscale flow with a very high damage potential. It is a massive challenge for NWP and forecasters to correctly predict a sting jet. The question is, can IASI profiles help forecasters for a better prediction of such mesoscale severe wind events connected with sting jets? In this specific context, some case studies will be presented.
