1) number of snow cover days
积雪日数
1.
The empirical orthogonal function method is applied to decompose the number of snow cover days of 240 meteorology stations in Hetao region and its vicinity(30°~43° N,102°~120° E) from 1961 to 2000;the temporal-spatial anomaly distribution in this area is analyzed.
利用河套及其邻近地区(30°~43°N,102°~120°E)240个地面气象观测站1951—2006年的积雪日数资料,采用EOF/REOF进行分解,分析了该区积雪的时空异常分布情况。
2) Yearly snow days

4) beginning date of snow cover
积雪初日
1.
The beginning date of snow cover in north is one month early than that in south.
5个月的可积雪期,积雪初日北早南晚,南北相差1个月;终日南早北晚,南北相差1。
5) ending date of snow cover
积雪终日
6) snowfall days
降雪日数
1.
Based on the relationship between annual winter mean temperature and snowfall days which was established according to the meteorological observation data in the Xi an and Hanzhong areas, the snowfall days for Xi an and Hanzhong areas derived from historical archives in the Qing Dynasty, the annual winter mean temperature in Xi an and Hanzhong areas from 1736 to 1910 A D.
基于现代气象资料所建立的西安、汉中地区冬季降雪天数与年冬季平均气温之间的相关关系 ,根据清代档案所记载的西安与汉中地区冬季降雪日数 ,恢复了西安与汉中地区 1736～ 1910年的年冬季平均气温 ,重建了 1736～ 1999年西安与汉中地区年冬季平均气温序列。
