“…This is true for both cyclonic and anticyclonic eddies (Figures b, c, e, and f). One important reason might be that the SCS is characterized with cyclonic circulation in winter (Quan et al, ). The intense southwestern boundary current may facilitate the southwest propagation of eddies in a large extend.…”

By analyzing 22 years (1993By analyzing 22 years ( -2015 of daily eddy data, statistics of surface eddy properties were refreshed in the South China Sea. More than 7,000 of historical Argo profiles were collocated into eddy-centered coordinates to reveal the composite mean three-dimensional structure of eddies. The results indicate that eddies of both polarities have long conical shape, with a maximum (minimum) density anomaly of 0.55 kg/m 3 (À0.51 kg/m 3 ) at 60 m (90 m) in the composite cyclonic (anticyclonic) eddy. Temperature and salinity anomalies also peak at eddy cores, with values of À1.5°C and 0.15 psu in the cyclonic eddy and 1.4°C and À0.16 psu in the anticyclonic eddy. The temperature and density anomalies extend vertically to 400-500 m, while the salinity anomalies are apparent only in the upper 150 m. The temperature anomalies contribute about 90% of the density anomalies. Mixed layer depths in cyclonic eddies are on average 15 m shallower than those in anticyclonic eddies. The rotation of the composite cyclonic (anticyclonic) eddy generates meridional heat transport of 1.4 × 10 12 W (À3.1 × 10 12 W) and salt transport of À4.0 × 10 4 kg/s (5.6 × 10 4 kg/s). More than 90% of the heat and salt transports are concentrated in the upper 300 and 100 m, respectively. Compared to the meridional transports, the westward propagation of eddies results in zonal heat and salt transports on the same orders of magnitudes. The westward propagation of eddies also generates a basin-scale westward water transport of 1.4 Sv, equivalent to about 30% of the annual-mean Luzon Strait transport. HE ET AL.4906

Berntsen et al (2016) conducted a high-resolution model experiment using a non-hydrostatic model to simulate plume down a canyon under rotation.…”

“…Based on field observations in 4 different seasons of 2010-2011and 15 numerical experiments, Qiao et al (2016 studied the seasonal sediment transportation and deposition in the Bohai Sea (BS) and Yellow Sea (YS) of the western North Pacific. The Yellow River is well known for high concentration of suspended particulate matter (SPM), which is one of the most important SPM sources in the BS and YS.…”

“…The western boundary current varies seasonally, it is driven by wind stress curl as well as inflow from the Luzon Strait (Xu and Oey 2015;Lin et al 2016), and modulated by rich interannual and interdecadal variability due to, e.g., the El Niño-Southern Oscillation and the Philippines-Taiwan Oscillation (Chang and Oey 2012). Quan et al (2016) propose that the South China Sea western boundary current (SCSWBC) should be defined as the current that flows southwestward and southward along the northern and western slopes of the SCS, while the flow along the Sea's southwestern shelf is considered as part of the locally wind-driven shelf circulation. The authors show analyses that support this view.…”

IWMO 2015 was held in the pristine campus of the Australian National University, Canberra, Australia, from June 1-5, 2015. Despite the negative Coriolis spin that many of us from the northern half of the globe experienced for the first time, we were positively impressed by the vastness and beauty of Australia and the kindness and friendliness of its people. Late fall in Canberra displayed spectacular starry nights and brisk sunny days. The workshop was attended by more than 80 participants from 16 countries around the globe. Seventy papers including both oral and posters were presented, covering a very broad range of topics on observations and models: climate variability, basin circulation and coastal oceanography, air-sea interaction, sea-ice dynamics, sediment transport, tropical cyclones, biogeochemical-physical coupling, boundary currents, sea level rise, extreme events, ocean prediction, and others. As in the past years, many of the participants were students and young scientists-all presented very high-quality research, and three were selected to receive the Outstanding Young Scientist Awards (OYSA). In order that some of us may have a chance to also receive some recognition for our hard work, new this year were three Best Presentation Prizes (BPP), given to any presenters deemed qualified by the audience to receive the honors. Also, new this year were special lunch-time sessions when young and more senior scientists exchanged ideas on a wide range topics.The 10 papers in this Topical Collection were selected from a total of 20 originally submitted papers after they underwent the usual process of reviews and revisions. There were at least 2 reviewers for each paper. The reviews were solicited from both the workshop attendees and the scientific community at large.

Interdecadal differences in the interannual variability of the winter monsoon over the South China Sea

We investigate interdecadal differences in the interannual variability of the South China Sea (SCS) Winter Monsoon (SCSWM) since 1950. The SCSWM is influenced by both the East Asian Winter Monsoon (EAWM) over the midhigh latitudes and the anomalous anticyclone over the western North Pacific (WNPAC). The EAWM tends to cause a positive linear correlation of wind speeds between the northern SCS (NSCS) and the southern SCS (SSCS). Because the cold surge of the EAWM can make wind speeds over the NSCS and SSCS increase simultaneously. While, the WNPAC tends to weaken this positive correlation (corNS) because anomalies associated with the WNPAC will decrease wind speeds over the NSCS but exert a small or even an opposite influence on wind speeds over the SSCS. The interannual variation of the EAWM before the late 1970s is greater than that after the early 1990s. And the WNPAC was weak and confined to the east of the SCS before the late 1970s but became strong and expanded towards the SCS after the early 1990s. As a result, the positive corNS was significant at the 95% confidence level before the late 1970s but became insignificant after the early 1990s.
