中美热带西太平洋海-气相互作用合作研究第四次科学考察工作于1988年4月20日-6月8日,历时50天、船程1500余海里,获得了大量调查资料,达到了预期目的,圆满地完成了任务。 本次科学考察的科学家和技术人员,中方50名、美方12名。调查海区为18°20＇N—10°30＇S、122°-165°E,观测了298个XBT站、106个CTD站,在这些测站上同时进行了海洋生物学、海洋化学中的26个要素的观测、分析。并且顺利地回收、施放大洋长期锚定浮标各一个,布放漂流浮标8个,多普勒声学海流测量8000余海里。本航次增加了气象全天空照像、太阳辐射记录、大气凝结核记录和气溶胶——冰核取样等项目。还收集了热带西太平洋海域大量的气象情报资料,为研究海-气相互作用、诊断埃尔-尼诺现象提供了科学依据。 本次作业虽难度大,其中有四条调查断面的部分测站距海岸近(只有3海里)、漂流速度大,且海底地形复杂、气象变化多端,给调查工作带来了很大困难,但在中美双方科研工 The fourth scientific expedition to the Sino-US tropical-western Pacific ocean-atmosphere interaction study took place on April 20, 1988 to June 8, 1988, which lasted 50 days and more than 1,500 nautical miles of the waterway. A large amount of survey data were obtained and the forecast was reached Purpose, successfully completed the task. The scientists and technicians for this scientific investigation have 50 Chinese and 12 U.S. counterparts. The sea area under investigation was 18 ° 20’N-10 ° 30’S, 122 ° -165 ° E, 298 XBT stations and 106 CTD stations were observed. At these stations, simultaneous observations of marine biology, marine chemistry 26 elements of observation, analysis. And successfully recovered, cast a long-term anchored ocean buoy a, laying drifting buoys 8, Doppler acoustic current measurement more than 8000 nautical miles. The voyage added meteorological all-sky photography, solar radiation records, atmospheric condensation nuclear records and aerosol - ice core sampling and other projects. Also collected a large number of tropical western Pacific Ocean meteorological information data for the study of sea-gas interactions, the diagnosis of El Nino phenomenon provides a scientific basis. Although this operation is difficult, some of the four surveyed sections are near the coast (only 3 nautical miles away), have a large drifting speed, and the seafloor topography is complicated and the meteorological changes are numerous, which has caused great difficulties in the investigation work. However, China and the United States both sides of scientific research workers
