“…During the passage of Typhoons Nari and Wipha, a large amount of rainfall led to increased discharge and stronger currents from the CRE, which could have carried vast numbers of phytoplankton. The increased level of Chl-a concentration might have also been derived from the subsurface via mixing and upwelling (Lin et al, 2003a, b;Babin et al, 2004;Miller et al, 2006;Fu et al, 2008Fu et al, , 2009aZhao et al, 2009). Second, many studies have shown that increases in remotely-sensed Chl-a concentration were misinterpreted in standard water color processing of MODIS data because of the contributions of the nearinfrared band for Case-II waters (Acker et al, 2002;Wren and Leonard, 2005;Hu and Muller-Karger, 2007).…”

“…In this study, the Chl-a concentration derived by MODIS clearly increased in the coastal waters after the passage of the typhoons, which might have occurred for three reasons. First, Zhao et al (2009) reported that the near-shore bloom in the Pearl River Estuary was probably due to increased discharge and favorable currents during the occurrence of a typhoon. During the passage of Typhoons Nari and Wipha, a large amount of rainfall led to increased discharge and stronger currents from the CRE, which could have carried vast numbers of phytoplankton.…”

This study investigated the eff ects of two typhoons (Nari and Wipha) on sea surface temperature (SST) and chlorophyll-a (Chl-a ) concentration. Typhoons Nari and Wipha passed through the Yellow Sea on September 13, 2007 and the East China Sea (ECS) on September 16, 2007, respectively. The SST and Chl-a data were obtained from the Aqua/Terra MODIS and NOAA18, respectively, and the temperature and salinity in the southeast of the study area were observed in situ from Argo. The average SST within the study area dropped from 26.33°C on September 10 to a minimum of 22.79°C on September 16. Without the usual phenomenon of 'right bias', the most striking response of SST was in the middle of the typhoons' tracks, near to coastal waters. Strong cooling of the upper layers of the water column was probably due to increased vertical mixing, discharge from the Changjiang River estuary, and heavy rainfall. During the typhoons, average Chl-a increased by 11.54% within the study area and by 21.69% in the off shore area near to the southeast ECS. From September 1 to 13, average Chl-a was only 0.10 mg/m 3 in the off shore waters but it reached a peak of >0.17 mg/m 3 on September 18. This large increase in Chl-a concentration in off shore waters might have been triggered by strong vertical mixing, upwelling induced by strong typhoons, and sedimentation and nutrient infl ux following heavy rainfall.

“…1, the biological response along the TC track is much stronger in coastal regions and higher latitudes than in the open sea. This is because the transport of suspended sediment from the river, as well as mixing and upwelling, can trigger a stronger phytoplankton bloom in coastal regions (Zhao et al 2009). Additionally, the response of phytoplankton to TCs may also be more pronounced in higher latitude regions where the mixed layer depth dramatically fluctuates due to the climatological conditions of the ocean and atmosphere (Moore and Abbott 2000).…”

“…Lin et al (2003) suggested that the contribution of TCs to annual new biomass production in the South China Sea may be 20-30%. By analyzing the ocean color data from satellites and in situ data, Son et al (2006) and Zhao et al (2009) also indentified phytoplankton blooms triggered by typhoons Megi and Nuri, respectively.…”

:We investigated the interannual relationship between chlorophyll concentrations in the western North Pacific and tropical cyclones (TCs) in the western North Pacific by analyzing data collected for >12 years. Despite the short-term scale (2~3 weeks) in the contribution of tropical cyclones to phytoplankton, the current study revealed that the long-term chlorophyll variability in the western North Pacific is profoundly related to long-term variability in the frequency of TCs. It was also found that the Pacific decadal oscillation (PDO) tends to control such relationships between the 2 bio-physical systems. This result suggests a significant climatic relationship between TC activity and marine phytoplankton, and also suggests the possibility of more accurate estimations of primary production in the western North Pacific.

Air–sea interaction in the South China Sea (SCS) has direct impacts on the weather and climate of its surrounding areas at various spatiotemporal scales. In situ observation plays a vital role in exploring the dynamic characteristics of the regional circulation and air–sea interaction. Remote sensing and regional modeling are expected to provide high-resolution data for studies of air–sea coupling; however, careful validation and calibration using in situ observations is necessary to ensure the quality of these data. Through a decade of effort, a marine observation network in the SCS has begun to be established, yielding a regional observatory for the air–sea synoptic system. Earlier observations in the SCS were scarce and narrowly focused. Since 2004, an annual series of scientific open cruises during late summer in the SCS has been organized by the South China Sea Institute of Oceanology (SCSIO), carefully designed based on the dynamic characteristics of the oceanic circulation and air–sea interaction in the SCS region. Since 2006, the cruise carried a radiometer and radiosondes on board, marking a new era of marine meteorological observation in the SCS. Fixed stations have been established for long-term and sustained records. Observations obtained through the network have been used to study regional ocean circulation and processes in the marine atmospheric boundary layer. In the future, a great number of multi-institutional, collaborative scientific cruises and observations at fixed stations will be carried out to establish a mesoscale hydrological and marine meteorological observation network in the SCS.
