摘　　要：根据1985—1989年中国科学院组织的西太平洋热带海域(0—5°N,110—150°E)综合考察过程中船载双通道微波辐射计五年累计获得的22599组观测资料,以及NOAA极轨卫星资料,综合分析了该海域中水汽总量和云液态水的统计特征及其年际变化,水汽场的整层与下层关系,可降水的日变化及空间分布等特征.指出了某些与陆地上不同的特点,为气候及海上边界层研究提供了有意义的观测事实.同时,给出了五年中辐射计探测与探空测值的统计比较结果.The statistical features of precipitable water (PW ) and cloud path-integrated liquid water content (pILWC) and their interannual variation, the relation of total and lower layer water vapor fields, and the diurnal variation and the spatial distribution of PW have been analyzed on the basis of 22,599 sets of data obtained by a ship-borne dualwavelength microwave radiometer and other observations, such as satellite data etc., during the 5 year comprehensive survey organized by Chinese Academy of Sciences over tropical area of the western pacific (0 - 5 ° N , 110-115 °E) from 1985 to 1989. Observations show that some features of PW and PILWC over the sea are different from those over land . The statistical comparison of the microwave radiometerderived precipitable water from the 5-year data with those by radiosondes is also given.
