| 摘 要： | 利用烟台地区1960～1999年的气象资料,分析了近40年来该区气温与降水量之间的关系.结果表明,从20世纪60年代至90年代,气温呈上升趋势,而全年、夏季、秋季降水量则随温度上升而减少,二者之间表现出显著线性相关.春季降水量与气温相关性不明显,二者不达显著水平.冬季降水量与冬季平均气温之间相关性显著,降水量随温度升高而增加,可用二次多项式回归方程量化表示.这样,该区气温状况如何,为预测未来降水趋势提供了信息,对合理利用本地气候资源具有实际意义. |

| Abstract: | Based on the weather data from 1960 to 1999 in Yantai area, the relationships between the air temperature and the precipitation have been analyzed in this region during the recent 40 years. The results show that the air temperature is increasing from 60's to 90's, but the precipitation of annual, summer and autumn is decreasing with the mean air temperature increased, and the significantly linear correlation have been shown. The correlation between spring precipitation and mean air temperature is not obvious, while the relation between the winter precipitation and air temperature is significant and can be shown by quadratic polynomial regression equation in the region. Thus, the air temperature status will provide information for forecasting precipitation tends in the future. It also can offer a basis for reasonable utilization of local climatic resource. |
