项目摘要

Seasonal and annual variations of column liquid water and precipitable water have been investigated using the SSM/I data of DMSP satellite. Meteorological radar and microwave radiometer observations were carried out at Syowa Station in 1988 and 1989. The Antarctic satellite data of 1988-1990 have been analyzed mainly, although the data of 1987-1995 have been dealt with. The Arctic data of 1992-1995 have been analyzed. The variation of 22 GHz and 37 GHz brightness temperature are roughly same as the variation of precipitable water and column liquid water in the atmosphere, respectively over open sea area. Some results of the brightness temperatures are described on behalf of those of column liquid water and precipitable water.High brightness temperature areas of 22 and 37 GHz were admitted near the off coast of Syowa Station according to the SSM/I image, when precipitation associated with low pressure was observed at Syowa Station. It was found that column liquid water was high in the e … More ast of the cloud band but was low in the west of cloud band. This result was similar to the characteristic of band cloud structure observed by meteorological radar at Syowa Station. The variation of precipitable water showed a peak aroung February, but the variation of column liquid water had two peaks in a year which were around February to April and around October to December. Total precipitation of 1989 was twice larger than that of 1988. Comparing the SSM/I images of 1988 and 1989 along the coast, the frequency of the days of high column liquid water was bigger in 1989 than in 1988. Especially, the big difference of both years was found around March to May and around October to November.It was found in the Arctic data that there were 2 periods with different values of precipitable water in a year. One was the period from May to October and others were from January to April and from November to December. The variation of 1993 data showed some difference from the data of other years. It might be related to the area of sea ice extension in three years in the Arctic. Maximum colum liquid water was 0.2 kg/m2 derived from SSM/I in the Arctic in 1992-1995, except 1993. Less
利用DMSP卫星的SSM/I资料研究了柱状液态水和可降水量的季节和年际变化。1988年和1989年在昭和站进行了气象雷达和微波辐射计观测。本文主要分析了1988-1990年的南极卫星资料,对1987-1995年的资料进行了处理。本文分析了1992-1995年的北极资料。22 GHz和37 GHz亮温的变化分别与大气中可降水量和柱状液态水的变化基本一致。根据SSM/I图像,在昭和站观测到低压降水时,在昭和站近海附近出现了22和37 GHz的高亮温区。结果表明,在实验条件下,柱内液态水含量较高, ...更多信息 在云带的东部,云带的西部低。这一结果与昭和站气象雷达观测到的带状云结构特征相似。可降水量的变化在2月份出现一个峰值,而液态水的变化在一年中有两个峰值,分别出现在2 ~ 4月份和10 ~ 12月份。1989年的总降水量是1988年的两倍。比较1988年和1989年沿着SSM/I图像,1989年高柱液态水出现的天数比1988年多。尤其是在3 ~ 5月和10 ~ 11月,两者的差异较大。一个是5月至10月,其他是1月至4月和11月至12月。1993年数据的变化与其他年份的数据有一定的差异。这可能与未来三年北极海冰面积的扩大有关。1992-1995年(1993年除外),北极地区SSM/I的最大柱液态水为0.2 kg/m2。少
