  4. OUTLINE • AIPO: Where and Why? • Key Scientific Issues • Subprojects of AIPO Program • Observation Plans & Some Progresses • Summary

  5. EastAsia TP Western Pacific Ocean SCS Indian Ocean The AIPO joining area

  6. WP Flow 台风源区 SAM EAM Typhoons invade AM Three monsoon systems interact

  7. 2. KEY SCIENTIFIC ISSUES The theme of the program is to identify the characteristics, patterns, and causes of air-sea interactions over the AIPO joining area and the intrinsic mechanisms of their impacts on the short-term climate anomalies over China.

  8. 3. SUBPROJECTS Western Pacific gyre interaction between tropics and subtropics and its relationship with the western Pacific anticyclone 1 Air-sea interaction over the Indian Ocean and its impacts on the Asian monsoon 2 Air-sea coupling process over Western Pacific-Eastern Indian Ocean warm pool and its impacts on the climate over China 3 Water cycle over Asian Monsoon Area 4 Development and improvement of CGCM 5 Ocean data assimilation and East Asia climate predictability 6 Modulation of air-sea interaction by land-sea thermal contrast 7

  9. WPSH 1st subproject:Western Pacific gyre interaction between tropics and subtropics and its relationship with the western Pacific anticyclone EA-WP Heat Transport

  10. 2nd subproject: Air-sea interaction over the Indian Ocean and its impacts on the Asian monsoon TP IO-EA EA Monsoon IO Air-sea

  11. 3rd subproject: Air-sea coupling process over Western Pacific-Eastern Indian Ocean warm pool and its impacts on the climate over China ENSO IO Zonal Mode EA Monsoon Warm Pool ISO IO-WP

  12. 4th subproject: Water cycle over the AIPO Area 突发性洪涝 Sudden flood 持续性旱涝 Persistent drought/flood Impacts of ocean thermodynamic and dynamic processes on Asian Monsoon hydrological cycle; The relationship of Asian Monsoon System and vapor transport track and intensity; Impacts of vapor transport anomalies on flood and drought in China; Observations of Air-sea fluxes over South China Sea.

  13. 5th subproject: Development and improvement of OGCM Development of a new Generation Oceanic General Circulation Model (OGCM):to describe wave-breaking and current-mixing processes; study influence of waves on air-sea exchange; improve short wave radiation penetration parameterization; develop a new OGCM. Improvement of Atmospheric General Circulation Model (AGCM):to study the influence of wave on air-sea flux exchange; to improve cloud parameterization; and to combine the radiating processes to enhance model performance. Assessment and development of air-sea coupling mode:to evaluate and promote the existing air-sea coupling model; to explore how the improvement of the specific physical processes can influence the integrating performance of the coupling model; and to further develop and improve air-sea coupling model.

  14. 6th subproject: Ocean data assimilation and East Asia climate predictability Ocean data assimilation: to improve ocean data assimilation technique; develop variant ocean data assimilation system of high spatial resolution for AIPO area. Predictability of ENSO and monsoon: the nonlinear behavior of ENSO events predictability dynamics and its impacts on East Asian Monsoon predictability; the mechanisms of “Spring Predictability Barrier” of ENSO events; to provide new thinking for ENSO and East Asian Monsoon prediction.

  15. 7th subproject:Modulation of air-sea interaction by land-sea thermal contrast Modulation of air-sea interaction over the Indian Ocean by land-sea thermal contrast over Asia-India-Australia area: reveal how land-sea thermal contrast over Asia-India-Australia area affects air-sea interaction over the Indian Ocean and the northern and southern hemisphere interaction, and to investigate how it affects the short-term climate variation in China. Modulation of air-sea interaction over Western Pacific by land-sea thermal contrast over Asian continent-Western Pacific: analyzing TP heat source structure, and seasonal to inter-annual variation patterns of the land-sea thermal contrast between Asian continent and Western Pacific to investigate its impact on East Asian circulation anomalies and air-sea interaction over Western Pacific. Impacts of land-sea thermal contrast over AIPO area on the interaction between high and low latitude in the stratosphere: to investigate the relationships among the large-scale land-sea thermal contrast, the air-sea interaction over AIPO area, and the stratosphere-troposphere dynamical and thermal coupling, and to establish their relationships with East Asian Climate anomalies.
