外文摘要：Using NOAA and MODIS(Tera & Aqua) satellites data, and mainly basing on 33 degree square as study area, the authors systematically analysis the effects of Sea Surface Temperature (SST) caused by 37 typhoons which passed by the Northwest Pacific Ocean from 2000 to 2008 and find: (1) In the Northwest Pacific Ocaea area, the SST without typhoon is averagely 26.10C, but the SST is averagely 22.90C during typhoon happened. The SST averagely decreases 3.20C with the drop rate of 11.55%, and the maximal fall of SST is 7.79C by typhoon. At the same time, the sustaining time with low SST is usually 25 days, and the time mainly lies on the lingering time of typhoon in the sea areas. After typhoon, the SST comebacks to the normal level before typhoon had happened.This can be seen clearly from the change of the SST before and after typhoon SAOMAI and LEKIMA. (2) In the study area of typhoon SAOMAI and LEKIMA passed througth, there are certain rightward bias of the distribution of the decrease of SST before and after typhoon. (3) The decrease of SST during typhoon is positive correlation with the wind speed and negative correlation with the moving speed of typhoon respectively and the correlation coefficient is less than 0.3, but it is better positive corrlation with the weight of typhoon and the correlation coefficient rises to 0.47.In conclusion, the effect of SST by typhoon is notable, and based on remote sensing to study this effects is effective means. ? 2008 SPIE.
