The concept of effective precipitation is provided in this study, the ratio of effective precip- itation and evaporation called as the effective moisture index is treated as the index of drought / flood damage.
提出有效降水的概念,并将有效湿润度(有效降水与可能蒸发量的比值)的异常程度作为判别指标,对西藏高原不同气候区域的旱涝特征进行了研究。
Based on the data accumulated during a period of more than 30 years at 2352 meteorological stationsover China and data from other sources,the existing Comprehensive and SequentiaI Classification Systemwas improved in this study by revising the original indices of thermal and humidity grades employed in thefirst-level classification of grasslands,that is the identification of grassland classes.
根据全国2352个气象站30年以上的气候资料以及其他资料,对草原的综合顺序分类法第一级分类的热量级、湿润度级指标进行了修正,设计了新的分类检索图,将地带性和非地带性(草甸和沼泽)的天然草地,以及人工草地的类,纳入到统一的检索图中,并可进行计算机检索。
Discusses the relationship between air humidity and some factors such as thermal balance, skin moisture, perception of clothing and thermal confort under steady-state.
讨论了在静态热环境下,空气湿度与人体热平衡、皮肤湿润度和人体对衣物的感觉以及人体热舒适之间的关系,分析了湿度瞬态变化对人体平均体表温度、热感觉和热舒适造成的影响。
