“…Dramatic effects of typhoons on chl-a levels, biological variables, and phytoplankton production have been reported several days following the passage of typhoons based on data from satellite color images or field experiments (Babin, et al, 2004;Chang, et al, 2008;Lin, et al, 2003;Shiah, et al, 2000;Walker, et al, 2005;Siswanto et al, 2007;Zhao, et al, 2008;Zheng and Tang, 2007). The satellite-derived SST data used in the present study clearly showed cooling after the passage of typhoons Fengwong and Sinlaku (Figs.…”

“…Many previous reports have focused on variation in SST (e.g. entrainment of cold, nutrient-rich water brought to the surface), surface ocean color images, and sea level anomalies between pre-and post-typhoon periods (Chang, et al, 2008;Lin, et al, 2003;Zheng and Tang, 2007). shows how SST in the area of the cold water patch changed over time following passage of typhoon Fengwong, with the lowest SST evident in the cooling core.…”

“…Recently, Wu et al (2008) and Chang et al (2009) reported a remarkable seasonal variability of this upwelling at depths of 100 m or more below the surface in summer, but such upwelling was weak in winter. In addition to such factors, typhoons may also enhance cooling in the SECS following passage of a typhoon through an adjacent region (Chang et al, 2008;Tsai et al, 2008). Tsai et al (2008) reported that a typhoon induced significant upper water column cooling off northeastern Taiwan.…”

The effect of typhoon on particulate organic carbon flux in the southern East China Sea

et al. 2010

Abstract. Severe tropical storms play an important role in triggering phytoplankton blooms, but the extent to which such storms influence biogenic carbon flux from the euphotic zone is unclear. In 2008, typhoon Fengwong provided a unique opportunity to study the in situ biological responses including phytoplankton blooms and particulate organic carbon fluxes associated with a severe storm in the southern East China Sea (SECS). After passage of the typhoon, the sea surface temperature (SST) in the SECS was markedly cooler (∼25 to 26 • C) than before typhoon passage (∼28 to 29 • C). The POC flux 5 days after passage of the typhoon was 265 ± 14 mg C m −2 d −1 , which was ∼1.7-fold that (140-180 mg C m −2 d −1 ) recorded during a period (June-August, 2007) when no typhoons occurred. A somewhat smaller but nevertheless significant increase in POC flux (224-225 mg C m −2 d −1 ) was detected following typhoon Sinlaku which occurred approximately 1 month after typhoon Fengwong, indicating that typhoon events can increase biogenic carbon flux efficiency in the SECS. Remarkably, phytoplankton uptake accounted for only about 5% of the nitrate injected into the euphotic zone by typhoon Fengwong. It is likely that phytoplankton population growth was constrained by a combination of light limitation and grazing pressure. Modeled estimates of new/export production were remarkably consistent with the average of new and export production following typhoon Fengwong. The same modelCorrespondence to: C.-C. Hung (cchung@ntou.edu.tw) suggested that during non-typhoon conditions approximately half of the export of organic carbon occurs via convective mixing of dissolved organic carbon, a conclusion consistent with earlier work at comparable latitudes in the open ocean.

“…They can trigger phytoplankton blooms by increasing primary productivity through oceanic eddies and upwelling near their paths (Chang et al 1996, 2008, Chen et al 2003, Lin et al 2003, Zheng & Tang 2007. In addition to the pre-typhoon depth of the mixed layer and strength of the pycnocline, the response of phytoplankton to typhoon forcing also depends on the translation speed and intensity of the typhoon itself.…”

Two phytoplankton blooms in the South China Sea (SCS), triggered by 2 typhoons with different intensities and translation speeds, were compared using remotely sensed chlorophyll a (chl a), sea surface temperature (SST), vector wind field, and best-track typhoon data. Typhoon LingLing in 2001 was strong, with a maximum sustained surface wind speed of 59 m s ) and 36% are slow-moving. We conservatively estimate that typhoon periods may account for 3.5% of the annual primary production in the oligotrophic SCS.

Using satellite-derived water transparency (alias Secchi depth) images, we found clear signals of terrestrial material transport to the southern Okinawa Trough triggered by the Typhoon Morakot in August 2009. Three sources were identified: one is from the eastern coast of Taiwan, another is from the western coast of Taiwan, and the other is from the coast of mainland China. Carried by northward flows, typhoon-triggered terrestrial materials from both sides of Taiwan's coasts were transported to the region northeast of Taiwan. Moreover, the terrestrial material from the coast of mainland China could cross the Taiwan Strait and be further transported to the region northeast of Taiwan. These typhoon-induced terrestrial materials off northeastern Taiwan could then be transported to the southern Okinawa Trough along the western edge of the Kuroshio. In addition to the particulate terrestrial material transported, nutrients might also be transported to the Kuroshio main stream. A significant phytoplankton bloom was observed along the Kuroshio path for about 300 km off northeast of Taiwan. Our results indicate that episodic cyclonedriven terrestrial material transport could be another source of mud in the southern Okinawa Trough.
