72. 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.

China Observations of Air-sea fluxes over South
China Sea.
135th 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.
146th 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.
157th 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.

21Some Progresses in Observations
- Water exchange across Karimata Strait and Java
coastal upwelling - A protocol between State Oceanic
Administration of China and Ministry of Marine
Affairs and Fisheries the Republic of Indonesia
in late 2006. - (1) Nov. 2007, observation equipments will
be deployed by use of Indonesia investigative
ships. - (2) Feb. 2008, a cruise will be initiated.
- (3) Nov. 2008, observation equipments will
be retrieved and replaced.
22The protocol was signed by SOA of China and MMAF
of Indonesia.
