  1. KORDI’s observation project focusing on the tropical western Pacific Jae Hak Lee (李載學) Korea Ocean Research and Development Institute NOAA OCO ASR, October 28, 2010, Silver Spring

  2. Hu et al. (2010) Background • Prediction of future regional climate • Understanding of climate change dynamics

  3. Background Nature (2009)

  4. GAIA Project (2009-2019) • Development of a high resolution climate model

  5. GAIA Project (2009-2019) Ocean Observation Time series data Large scale Air-sea interaction Mixing parameterization Climate Change Science Data Assimilation System Reanalysis data Analysis of modeling results Improvement of model High Resolution Climate Model IPCC 6th Report

  6. Target area (model & observation)

  7. Themes of observational foci • Mixing parameterization - Sub grid scale phenomena • Ocean monitoring - Upper layer in the equatorial Pacific - Low latitude western boundary currents - Indonesian through flow

  8. Parameterization • Important for climate model • Atmosphere - Cloud • Ocean - Surface mixed layer mixing -Thermocline mixing

  9. Equatorial thermocline mixing • Predominance of small vertical scale structures in the velocity field • New ocean mixing parameterization schemes is needed

  10. Thermocline mixing • Upper 400 m depth along a TAO/TRITON line • CTD, LADCP/600kHz, MSP, (Glider) • 2009 ~ 10 : planning, pilot cruise • 2011 ~ 12 : main experiment - KORDI / IPRC(UH) / JAMSTEC - 2010: RV Mirai, 2011: RV Onnuri, 2012: RV Onnuri, US ship

  11. Monitoring (Equatorial upper layer) • TAO/TRITON extension • KORDI - NOAA cooperation • 3 Data buoy & 2 ADCP mooring • 2010 ~ 11: planning • 2013 ~ : field campaign

  12. Monitoring (LLWBC & ITF) • Current meter mooring & hydrographic survey • 2010 ~ 2011: planning - NPOCE (CLIVAR endorsed project) - ITF monitoring program • 2012 or 2013 ~: field campaign

  13. NPOCE Northwestern Pacific Ocean Circulation and Climate Experiment • CLIVAR endorsed project • Themes of Scientific Foci • Western Boundary Currents • Interaction with Ambient Circulation Systems • Roles in Warm Pool Maintenance and Variability • Regional Air-sea Interaction and Climate Impacts

  14. NPOCE observation

  15. NPOCE roadmap

  16. Gordon (2005) ITF Monitoring

  17. KORDI, Indonesia KORDI Indonesia, JAMSTEC/Japan USA, Indonesia LDEO/USA, FIO/China, Indonesia Indonesia, LOCEAN/France LDEO,NOAA/USA, Indonesia CSIRO/Australia ITF Monitoring
