  1. The effect of Typhoon on SSS in Summer of 2002 and 2003 XU Dongfeng Second Institute of Oceanography, SOA, Hangzhou 310012, China;

  2. Kwon & Riser(2002) Dennis(1999) Atlantic Typhoon effect to SSS in Atlantic by Riser XU Dongfeng

  3. ARGO Floats of Jan to Oct in 2003 and 2002maximum velocity about 6cm/s (55km/10days)

  4. The surface velocity is about 30cm/s; (250km/10days)

  16. Argo 2900184(circle); 5900126 (triangle); 5900173 (diamond) 5900175 (star) July 2003 track Linfa (May25-30, blue); Soudelor (Jun11-19, green, ); Imbudo (Jul16-24, blue); Krovohn (Aug15-25, black); Etau (Aug03-09,red) 5900222 5900223

  17. 5900222 SSS

  18. 5900223

  19. S of 5900219(08173) by Linfa

  20. S of 5900220 by SOUDELOR

  21. 5900266: 2002/03

  22. SSS of 5900222(21299) and 5900223 sensitive to distance from Imbudo and Krovahn 5900222 5900223 5900222 5900223

  23. Discussion • The cause of SSS variation: 4 processes competition Rain Evaporation Typhoon Enhansed mixing upwelling

  24. Discussion • Further modelling: 4 processes can be simuated by a 1D model to check the mechanism. Rain Evaporation Typhoon Enhansed mixing upwelling

  25. conclusion In WETPAC some Typhoon make the SSS decreasing. Most of SST decreased after the pass of Typhoon The development of Barrier Layer after the Typhoon rain. Are there differences between the Atlantic and WESTPAC in SSS ???
