The South China Sea conflict has been a highly sensitive issue for the last 5 years in ASEAN. China and the US have been using the South China Sea as the New Cold War Arena of power and military hegemonic competition in the South East Asia region. This has been a major challenge for ASEAN as the only regional organization in the South East Asia region that has direct in the area must take major role in managing and resolving the dispute peacefully even though ASEAN has no defense pact like NATO. This paper argues that ASEAN, at this moment, must maintain its role as a mediator and independent-negotiator in the region but at the same time apply its principle of gradually adapting with the new international system. This article also suggests that in the future, ASEAN can take a major role in the governance of the South China Sea and the South East Asia region.

"Abstract: This paper analyzes the South China Sea dispute when the international system lacks orientation and respect for the norms, values, and institutions. The conflict is conceptualized to encompass the States, International Law, and the East Asia order. The evidence demonstrates that ASEAN’s regional order is more efficient than the US-Led Liberal order through UNCLOS. Additionally, it is necessary to overhaul and strengthen the institutional mechanisms from international law regarding the United Nations. A change in the order and an international recognition are recommended to legitimize regional institutions to arbitrate territorial disputes. Keywords: ASEAN, regional order, conflict resolution, South China Sea Dispute."

Numerical Studies

<p>South East Asia seas, that include the South China Sea and the Indonesian Seas, transfer the warm and light waters of the surface branch of the global thermohaline circulation between the Pacific and Indian Oceans. To better understand the key contribution of South East Asia seas in the regional and global climate and ocean circulation, it is therefore essential to improve our knowledge of the functioning and variability at different scales of water, heat and salt budgets over this region. The complex topography of this region makes it difficult to study those budgets based on in-situ measurements only. Numerical studies are necessary and relevant to complement and interpret those measurements, however until now, most of numerical studies were performed at low resolution and/or on short periods.</p><p> </p><p>To better quantify and understand the contributions of ocean, rivers and atmosphere to the variability at different scales of the water, heat and salt budgets over South East Asia seas, high resolution configurations (< 5 km) of the SYMPHONIE ocean model are developed over the area. State of the art datasets available from COPERNICUS and ECMWF are used to prescribe boundary conditions. Each term of the budgets is computed online in order to obtain rigorously closed budgets.</p><p> </p><p>This methodology applied on the 2009-2018 period, that includes strong El Niño and La Niña years as well as neutral years, allows us to better characterize the seasonal to interannual variability of water, salt and heat budgets over the South East Asia seas, by quantifying and explaining the contribution of each factor (lateral fluxes, surface fluxes, rivers, internal variations, ENSO). We examine in particular the surface salinification of the South China Sea that was observed by previous authors between 2012 and 2016 (Zeng et al. 2018, doi:10.1002/2017GL076574) : our simulations suggest that it is mostly related to an increase of net lateral water influx at Luzon strait, itself induced by a deficit of precipitation over the region, rather than to an increase of the salinity of the inflowing water. We finally also explore the role of tides and mesoscale processes. This methodology, our key results and the future steps of this work, that include the on-going development of an ocean-atmosphere regional coupled model, will be synthetically summarized.</p>

Extratropical Circulation

AbstractCold surges occur frequently over the South China Sea (SCS) in winter, and most of them last only a few days. However, some cold surge events can persist longer, for instance, more than 5 days. This study focuses on these long-lived cold surge events and investigates the associated extratropical circulation anomalies. The results indicate that long-lived cold surges, characterized as strong northerlies over the SCS, can be triggered by a successive high anomaly center over East Asia. Accompanying this is an anomalously extensive and quasi-stationary anticyclone over Siberia in the midtroposphere, hinting at a more frequent occurrence of Siberian blocking. Further analyses reveal that the blocking frequency is indeed significantly high over 90°–150°E from day −4 to day +2 relative to the onset of long-lived cold surge events. Furthermore, there exist significant correlations between the leading occurrence of Siberian blocking and the sea level pressure (SLP) anomalies over East Asia, which are directly related to long-lived cold surges. The intensification of the high SLP anomaly over East Asia is found to mainly result from cold advection induced by the anomalous northerly winds along the southeastern edge of the Siberian blocking.

Abstract Analysis of the NCEP and 40-yr ECMWF Re-Analysis (ERA-40) data and the Xisha Island station observation indicates that the low-level meridional wind (LLMW) over the South China Sea (SCS) experienced an interdecadal variation since the late 1970s. The LLMW change is associated with the reduction of tropospheric temperature in midlatitude East Asia. A mechanism is put forward to explain the triggering and maintenance of the tropospheric cooling. The enhanced convective heating over the southern South China Sea results in a meridional vertical overturning circulation, with anomalous descending motion appearing over continental East Asia. The anomalous descending motion reduces the local humidity through both anomalous low-level divergence and dry vertical advection. The decrease of the local tropospheric humidity leads to the enhanced outgoing longwave radiation into space and thus cold temperature anomalies. The decrease of the temperature and thickness leads to anomalous low (high) pressure and convergent (divergent) flows at upper (lower) levels. This further enhances the descending motion and leads to a positive feedback loop. The fall in tropospheric temperature over continental East Asia reduces the land–sea thermal contrast and leads to the weakening of cross-equatorial flows and the LLMW over SCS. A further diagnosis indicates that the LLMW is closely linked to the summer precipitation and temperature variations in China on interdecadal time scales. A weakening of the LLMW after 1976 is associated with a “−, +, −” meridional rainfall pattern, with less rain in Guangdong Province and north China but more rain in the Yangtze and Huaihe River basins and northeast China, and a “+, −, +” temperature pattern, with increased (decreased) surface temperature in the south and north (central) China.
