  • There are three triply nested WRF forecast domains with grid spacing of 27/9/3 km.
  • The system is initialized before the storm developed, and cycling the assimiltion with all conventional observations, Recon and TDR data every 3 hours till the end of the storm.
  • APSU: PSU 3-km deterministic forecast with EnKF data assimilation
  • GFS: NCEP Global Forecast System
  • The APSU figures are plotted by combined all 3 domains, the square denotes the 3-km domain position.
