摘  要:
为了提高降水量预报的精度,使用随机森林预报江淮各省会城市2006—2015年的夏季降水量,并将预报量与实际观测量进行对比。结果表明,在使用环流因子作为预报因子的情况下,基于随机森林的郑州、武汉以及南京的降水量预报结果无论是在精度还是稳定度上都要高于合肥。

摘  要:
In order to improve the precision of precipitation forecast, the random forest is used to forecast the summer precipitation in provincial capitals of Jianghuai area from 2006 to 2015. The results show that, when the circulation factors are used as the prediction factors, the precipitation forecast based on the random forest in Zhengzhou, Wuhan and Nanjing are better than that in Hefei.
