  4. ”NOWCAST” ? T = 0 T = 24 hrs time sea levels currents

  5. CONCEPT of TSNOW WWW • Disaster warning • Marine rescue • Pollutant dispersion • prediction • Scientific study • Environmental • policy making • Marine resources • management Observations Prediction Demonstration Applications

  6. OBSERVATIONS Sea levels from tide gage station Velocities from BM-ADCP Velocities from SB-ADCP T and S from CTD Observations

  7. NUMERICAL MODEL Model resolution Boundary conditions Prediction

  8. MODEL DEVELOPMENT Stage 1 Stage 2 Stage 3

  9. VALIDATION FOR SEA LEVELS Black-observed Red -calculated Kaohsiung Dongee

  10. VALIDATION FOR CURRENTS Blue - currents measured using ship-board ADCP mounted on OR-I Red - currents extracted from model results

  11. DEMONSTRATIONS Penghu Islands Dongee -24 0 +24
