前期降雨 meaning in English
antecedent rainfall
Examples
- Slope stability is analyzed according to rainfall intensities , prophase total rainfall , different soil slope gradients and vegetation by saturated - unsaturated seepage theory
摘要在饱和非饱和渗流理论基础上，从降雨强度、前期降雨总量、不同的土坡坡度以及是否考虑植被护坡等方面对大气降雨条件下土坡的稳定性进行了探讨。 - The biggest diurnal albedo is 0 . 24 and the smallest 0 . 11 . moreover , the peak occurs on the day that radiation is very strong and the soil surface is dry and the valley appears on the day that rainfall is much more before this day and the soil water content of upper layer is high
就反射率的日际变化而言，最大反射率为0 . 24 ，最小为0 . 11 ，相差一倍以上，其峰值均出现在辐射比较强，地表比较干燥的日期，而谷底一般是在前期降雨较大，表层土壤湿润时出现。 - Taking into account weather and flood forecast information ; the forecast operation manner is studied under the condition of without the change of the existing flood control standard to realize the conversion of flood control and benefits . ( 4 ) through analyzing runoff and water utilization information during reservoir operation , design flood , and the existin
水库汛阳水位动态控制方法研究及其风险分析根据水库流域天气预报、流域前期降雨、水库蓄水、水库泄水能力和防洪兴利要求，利用水库汛限水位变动范围，结合洪水预报和短期降雨预报模型，研究水库汛限水位动态控制方法。 - We systemically discussed the distribution of precipitation , dynamics of soil erosion in different land - use types , the relation between soil and water losses and some rainfall characteristics , such as rainfall amount , intensity , duration and prophase rainfall . further , rainfall erosion force was discussed and regression equations between soil and water losses and rainfall characteristics were founded
较为系统的探讨了闽江上游地区的降雨分布特征，不同土地利用方式的水土流失动态，不同土地利用方式水土流失与降雨量、降雨强度、降雨历时、前期降雨等的关系，在此基础上，初步探讨了闽江上游的降雨侵蚀力，并建立了不同土地利用方式水土流失与降雨特性有关的回归方程。
