凤阳一次强降雨过程自动土壤水分观测数据分析

Analysis of Automatic Soil Moisture Observation Data during a Heavy Rain in Fengyang

该文选取安徽凤阳2015年主汛期一次强降雨天气过程,分析其对应时段自动土壤水分观测数据的变化特征;运用土壤水分观测计算的基本原理,分析观测结果存在的主要问题,提出一种改进观测数据可用性的订正方法。实例计算结果表明,此订正方法能有效减小原始观测值的系统偏差,使观测结果更为合理、可信。

This article selects a heavy rain weather process in Fengyang of Anhui Province in 2015,and analyzes itscorresponding time automatically change characteristics of soil moisture observation data.Using the basic principle ofcalculating soil moisture observation,the paper analyzes the main problems of observation results,and puts forwardan improved correction method of observation data availability.Correction calculation results show that the algorithmcan effectively reduce the original observation system deviation,thus make the observation results more reasonableand credible.
