JPSS for Extratropical Transition

Extra-tropical transition:

  • The storm structure change
  • Storm size can increase dramatically
  • Most often occurs north of ~ 40 N
  • Can occur down to 20 N in the Atlantic
  • On average there are ~ 15 TS-ETC per year in all global basins
  • Storm type could significantly affect forecast, especially when occurring right before the landfall
  • Changes in storm size and structure during ET are important for forecasting storm impatc (2012 Sandy, 2022 Nicole) and risk mitigation

JPSS data, including ATMS and VIIRS provide model-independent information that can be used to improve storm type classification.
