| 摘 要： | 与常规方法不同,根据全国58个基准气象台站10年的日记温度湿度数据采用每天2点、8点、14点、20点的4次数据统计了各台站3种临界相对湿度(80%、70%、60%)时的年润湿时间,并对比分析了24次(每天整点)数据的统计结果.研究表明从这两种数据所统计的相应有效年润湿时间非常接近,而且随着临界相对湿度值的降低,这种趋势更为明显,证实了采用4次数据统计年润湿时间是可行的.这样可以充分利用全国550多个基本气象台站所上报的4次温度湿度数据来研究全国润湿时间分布规律,为评估我国各地的大气腐蚀等级奠定了基础.

| Abstract: | The TOW values of 58 benchmark meteorological stations were calculated based on 4 times data of 10 years daily records and the comparison was made to 24 times data. It was proved that two kinds of statistic values of effective annual TOW is very close and become closer with the decrease of critical humidity. It is feasible to use 4 times data to make statistic of TOW. The general distribution of TOW in the whole country can be calculated with 4 times data from 550 basic meteorological stations and then the atmospheric corrosivity of main land China can be evaluated with this foundation. |
