“…Meanwhile, results demonstrate that winter season net westward through LS is ca. 3.8 10 times higher than summer season, and this is consistent with plenty of field observations (Lan et al, 2004), and numerical models carried out in the LS (Fang et al, 2005;Song, 2006;Yaremchuk et al, 2009;Zhao et al, 2009b). For the LSL condition with doubled wind speed enforcement (HQSK2), increased westward transport results in a residence time of 18.4 years, which is nearly the same as that of the PSL condition.…”

“…We also estimated one-point correlation with the reference point at (108 • E, 8 • N) which has the largest standard deviation in Figure 3(a) (not shown). The entire SCS has a large positive correlation, indicating the pervasive dynamical influence of the cold tongue in the SCS and the SST around the Strait of Karimata and the western part of the Java Sea (3 • S-6 • S and 105 • E-110 • E) changes in phase with the cold tongue due to the southward cross-equatorial current in winter (e.g, Fang et al, 2009;Qu et al, 2009). Therefore, we can consider that the influence of the cold tongue on SST reaches the Strait of Karimata and the western Java Sea.…”

We investigate the effects of the cold tongue in the South China Sea (SCS) on the winter monsoon, rainfall and diurnal cycle in the maritime continent using a numerical model verified with satellite rainfall and reanalysis data. Composite analysis of the observation and reanalysis data based on cold tongue index indicates that the penetration of the monsoon to Java Sea is enhanced when the cold tongue is strong. A sensitivity experiment without the cold tongue shows that the winter monsoon is diminished over SCS and around coastal regions because of anomalous low-level cyclonic circulation associated with enhanced convection over SCS due to the warmer sea surface temperature (SST). The diurnal cycle, in particular the night-morning rainfall, over the sea in coastal regions is modified. The effect on daytime rainfall over the land is relatively weaker. Along the northern coast of Java far from the SCS, the night-morning rainfall is much reduced over the Java Sea when the cold tongue is suppressed because of the weakened land-breeze front as a result of the weakened northerly monsoon. In contrast, the afternoon-evening rainfall on Java Island is slightly enhanced, showing that the local impacts are not simply the result of large-scale subsidence from the convective anomaly in the SCS. Along the northwestern coast of Borneo adjacent to the SCS, the weakened winter monsoon tends to reduce the rainfall at the land-breeze front near the coastline. On the other hand, the warmer SST forces a stronger land breeze and the weakened monsoon encourages further and faster offshore propagation of the land-breeze front. Consequently, the rainfall peak shifts further offshore in the sensitivity experiment. We conclude that the cold tongue has two effects, the sustenance of a strong monsoon (indirect effect) and the cooling of local SST (direct effect), which have opposite influences on the diurnal cycle in the Maritime Continent.

“…The CCC starts in mid-September, peaks from October to January and weakens thereafter (Jan and Chao, 2003;Lin et al, 2005;Wu and Hsin, 2005;Pan et al, 2012). A number of studies have investigated the water volume transport through the TWS, either based on field measurements using shipboard acoustic Doppler current profilers (sbADCPs) Wang et al, 2003), bottommounted acoustic Doppler current profilers (bm-ADCPs) (Lin et al, 2005;Jan et al, 2006), surface drifters (Qiu et al, 2011), or high-frequency radar (Zhu et al, 2008), or based on numerical models (Jan et al, 1998;Wu and Hsin, 2005;Wu et al, 2007;Fang et al, 2009). However, studies dedicated to assessing the total volume transport of the CCC and its variability and biogeochemical significance have not yet been conducted.…”

Inter-shelf nutrient transport from the East China Sea as a major nutrient source supporting winter primary production on the northeast South China Sea shelf

et al. 2013

Abstract. The East China Sea (ECS) and the South China Sea (SCS) are two major marginal seas of the North Pacific with distinct seasonal variations of primary productivity. Based upon field observations covering both the ECS and the northern SCS (NSCS) during December 2008-January 2009, we examined southward long-range transport of nutrients from the ECS to the northeastern SCS (NESCS) carried by the China Coastal Current (CCC) driven by the prevailing northeast monsoon in wintertime. These escaped nutrients from the ECS shelf, where primary production (PP) was limited in winter, might however refuel the PP on the NESCS shelf at lower latitude, where the water temperature remained favorable, but river-sourced nutrients were limited. By combining the field observation of nitrate+nitrite (NO 3 +NO 2 , DIN) with our best estimate of volume transport of the CCC, we derived a first-order estimate for DIN flux of 1430 ± 1024 mol s −1 . Under the assumption that DIN was the limiting nutrient, such southward DIN transport would have stimulated 8.84 ± 6.33 × 10 11 gC of new production (NP), accounting for 33-74 % of the NP or 14-22 % of PP in winter on the NESCS shelf shallower than 100 m.
