摘要
确立以日蒸发量来作为描述可晾晒程度的物理量。根据日蒸发量与日最高温度、日平均相对湿度等诸多因子的相关性 ,进行回归计算 ,建立其预报方程。通过数轴凝聚 ,对 1998、1999年常州市气象站的逐日蒸发量的变化范围并结合天空状况等因素进行分类 ,以此作为晾晒指数等级的划分标准。将方程结果与标准相对照 。
It is established that the day evaporation is the physical quantity of describing the level of drying.Based on the day evaporation,the day top temperature and the day average opposite humidity etc,forecast equation is calculated and built up.Combined with the sky conditions etc,the changing range of Changzhou Meteorological Station′s day evaporation in 1998 and 1999 is classified by condensing number axis,which is used for the dividing criterion of drying index grade.The next day′s drying index grade and relevant decision are given after we compared the results of equation with the criterion.
