( 5 ) parameterization of infrared satellite cloud imagery and its application in rainfall predication obvious correlation exist between the probability of rain and parameterization estimate such as average brightness temperature ( tb ), brightness temperature variance ( f ), equivalent cloudage ( cn ), brightness temperature area index ( al - the first a5 - the fifth grade, a6 - the sixth grade )
（ 5 ）衛星雲圖參數化及在降雨預測中的應用紅外衛星雲圖參數化估計值，與局地降雨過程的發生、發展具有較為密切的關系。相關較密切的參數有平均亮溫、亮溫方差、等效雲量、亮溫面積指數（ 1級、 5級、 6級） 。 -
The probability density function of net rainfall relative errors, flood peak discharge relative errors and the time error of the forecasted flood peak are calculated by the model developed
通過建立洪水預報誤差分佈的最大摘模型，計算出9座典型水庫洪水預報的凈雨相對誤差、洪峰流量相對誤差和峰現時間預報誤差的概率密度函數，並將其概率密度函數曲線與正態分佈曲線進行比較。 -
From the angle of uncertainty of inflow and water consumption, the risk of water dispatching on the lower reaches of the yellow river is analyzed. inflow series are generated by use of the method of representative disaggregation. water consumption series are generated according to rainfall probability distribution. a model for risk analysis of water dispatching is established with the technique of stochastic simulation, and a quantitative description of risk is presented, thus, making the water dispatching decision - making more scientific
從來水和用水不確定性角度分析黃河下游水量調度風險.對來水採用典型解集方法生成來水系列，對用水根據降雨概率分佈生成用水系列，利用隨機模擬技術建立了水量調度風險分析模型，給出風險的定量描述，從而使水量調度決策更加符合實際 -
Except haiyuan and yanchi counties, which are 83 %, a bit lower than the theoretical probability value of 84. 13 %, the rainfall of other five counties is larger than the theoretical probability value. this indicates that, within certain rainfall range, the annual rainfall is much stable
從實際的40年降水資料看，可近似估計該區降水量（ x ? 1s ） mm的出現頻率大於84 . 13 ，表明在一定的降水量范圍內，其年降水量又有一定的穩定性。
