珠江口以西陆架夏季上升流的研究

本文主要依据南海北部珠江口以西陆架区1977～1981年的水温、盐度和溶解氧饱和度等要素的序列历史资料,对该海域的上升流现象进行了分析研宄。     

九龙江口和厦门西港的盐度低频变化特征

本文根据厦门海洋站长序列盐度观测结果，分析九龙江口和厦门西港各种时间尺度的盐度低频波动特征，并探讨其机制。结果表明，九龙江径流量是影响厦门盐度的主要因素，但不是唯一因素。在亚潮频段。盐度对径流的响应可能有相当强的非线性。     

中国主要海湾生物区系分析

根据《中国海湾志》所提供的生物数据,分析了中国由北向南四大主要海湾集群(辽东半岛东部海湾、上海市和浙江省北部海湾、浙江省南部海湾、海南省海湾)的生物分布现状,并采用Jaccard指数和sβim多样性指数计算比较了这4个海湾的生物分布情况.结果表明,中国海湾的生物分布,在生物数量上和特有种数量上并不完全符合由高纬度向低纬度递增的趋势,而且辽东半岛海湾邻近的黄海特殊海流特性给这里带来较特殊的生物分布.中国4个海湾的数据有条件的支持几何限制因素假说.同时,人类活动显然对海湾生物产生一定的影响.     

南海上层环流观测研究进展

回顾了近50a来南海环流研究的进展，重点介绍了近期有关南海上层总环流的观测研究成果，并就南海季风急流、南海暖流、南海南部的次海盆尺度环流，以及南海东北部环流的几个问题进行了专门讨论。     

南海冬季之西边界流：1998年2月的水文结构与体积输运

The unique survey in December 1998 mapped the entire western boundary area of the South China Sea(SCS),which reveals the three-dimensional structure and huge volume transport of the swift and narrow winter western boundary current of the SCS(SCSwwbc) in full scale. The current is found to flow all the way from the shelf edge off Hong Kong to the Sunda Shelf with a width around 100 km and a vertical scale of about 400 m. It appears to be the strongest off the Indo-China Peninsula, where its volume transport reached over 20×10~6 m~3/s. The current is weaker upstream in the northern SCS to the west of Hong Kong. A Kuroshio loop or detached eddy intruded through the Luzon Strait is observed farther east where the SCSwwbc no more exists. The results suggest that during the survey the SCSwwbc was fed primarily by the interior recirculation of the SCS rather than by the"branching" of the Kuroshio from the Luzon Strait as indicated by surface drifters, which is likely a near-surface phenomenon and only contributes a minor part to the total transport of the SCSwwbc. Several topics related to the SCSwwbc are also discussed.     

SEA LEVEL ALONG THE SOUTHEAST COAST OF CHINA DURING EL NINO

In El Nino years, along the southeast China coast, the seasonal cycle of sea level variation - low in spring, high in autumn - is attenuated: specifically, the autumn peak is reduced by about 10 cm. This negative anomaly increases toward the south and occurs at the same time as a similar (but five times larger) sea level anomaly at Truk Island (7.5°N) in the western Pacific.     

作为一种预报手段的诊断分析

1.对天气尺度结构的诊断分析做了诊断再给出的预报,逻辑上是从天气尺度开始的,大尺度系统给出了所有可能产生中尺度现象的因子.如雷暴需要水汽、不稳定层结和抬升源,也许在分析过程中就能给出三个因子中的两个.由于所忽略的另一个因子会增大雷暴发生的潜在可能性,大尺度诊断能指出应该注意什么. 能够证实,自动图表分析节省了时间,但却忽视了这样一个重要事实:分析者从计算
