| The Significance Level of Stable Isotope Thermaometer of Precipitation in China |
| According to multi-year average values from 32 stations in Chinese network, a good linear relationship with the significance level α=0.01 exists between δ-values of precipitation and surface air temperature. The H-isotope thermometer is about 3.1‰/℃,and the O-isotope thermometer is about 0.36‰/℃.The stations with the significance level of α=0.01 and the monthly isotope thermaometer >0 are located in North China(to the north of the Qinling Mountain and the Huaihe River) with latitude from 37°N up to larger than 47°N, where the determination coefficients are 0.41≤R2≤0.73 in the west stations and 0.14≤R2≤0.56 in the east stations and the monthly O-isotope thermometer ranges from 0.10 to 0.65‰/1℃. The stations with the significance level of α=0.01 and B<0 are located in south China (to the south of the Qinling Mountain and the Huaihe River) with low latitude,i.e. from latitude of 32°N down to 20°N,where the determination coefficients are mostly R2<0.5 and the monthly O-isotope ther-mometers are wholly <0. Some of the stations witha =0 and 0.0002 |
