1997年北方酷暑、1998年长江特大洪水与东海陆架的温盐度分布

Northern China's intense heat in summer 1997, the Changjiang River's catastrophic flood in 1998, and the T-S distribution in the shelf of the East China Sea

根据 1 996～ 1 999年的标准断面资料及 1 997、1 998年夏季的 6幅卫星遥感温度图像 ,初步分析了黄、东海 2 7°～ 34°N观测区的温、盐度分布。认为 1 997年测区内的温、盐度分布具有明显的特色 ,而 1 998年长江特大洪水主要是对 30°N以北海域上层有所影响。综合 4年中 8月份的温、盐度分布态势 ,夏季气温比较正常的 1 996年与 1 998年两年测区内的温、盐度分布比较类似 ,而都属北热南凉的 1 997年和 1 999年两年测区内的温、盐度分布也较为类似。

Based on four year's standard sectional data from 1996 to 1999 and some remote sensing data in summer 1997and 1998, the \%T\|S\% distribution in the survey area of 27°\|34°N in the Yellow Sea and the East China Sea was primarily analyzed and it is found that the \%T\|S\% distribution of this area in 1997 has distinct feature; The Changjiang River's catastrophic flood in 1998 mainly affected the upper layer \%T\|S\% distribution in the area north of 30°N. Synthesizing of the \%T\|S\% distribution situations in August for 4 years, it shows respectively that it had the similar features in 1996 and 1998 for normal season temperature and appeared the similar characteristics in 1997 and 1999 for the cooler summer in the southern and the hotter in the northern.
