Research on Cold Core Eddy Change and Phytoplankton Bloom Induced by Typhoons: Case Studies in the South China Sea

Figure 9

The chl-a blooms under the influence of typhoons in the CCE area. Colorbar is the natural logarithm value of chl-a concentration. The thick black solid lines in figures are typhoon tracks. The closed contours are the CCEs influenced by typhoons. (a) Typhoon Nanmadol in December 2004. chl-a concentration is from 2 December to 9 December. (b) Typhoon Kai-tak in November 2005, and chl-a concentration is from 1 November to 8 November. (c) Typhoon Chanchu in May 2006, and chl-a concentration is from 17 May to 24 May. (d) Typhoon Durian in December 2006, and chl-a concentration is from 3 December to 10 December. (e) Typhoon Utor in 2006, and chl-a concentration is from 11 December to 18 December. (f) Typhoon Lingling in 2001, and chl-a concentration is from November 9 to November 16.
