Abstract

The temporal variability of rainfall in Quirino Province was analyzed through the use of rainfall data of seven (7) rain gauges within the neighboring provinces like Nueva Vizcaya and Aurora. The length of record analyzed from 1997 to 2016. In this study, rainfall frequency analysis and consistency of rainfall data from the different stations through the use of double mass curve analysis was performed and analyzed. The annual series was used to screen each station’s annual rainfall data while the province’s average Thiessen rainfall was screened using maximum period series process. It was found out that all the data of the seven (7) rainfall stations were consistent. To attain allowable error in estimation of 10%, 5% and 1% for the mean annual rainfall the number of rain gauge station needed in the province should be 18, 72 and 1799, respectively.

基里诺省降水变率分析

利用新比斯开省、奥罗拉省等邻近省份7个雨量计的降水资料，分析了基里诺省降水的时间变率。分析了1997年至2016年的记录长度。本研究利用双质量曲线分析方法，对不同台站降雨资料进行了降雨频率分析和一致性分析。采用年序列法筛选各站点的年降雨量数据，采用最大周期序列法筛选全省平均降雨量。结果表明，7个站点的数据基本一致。为了使年平均降雨量的允许误差达到10%、5%和1%，全省需要的雨量站数量分别为18个、72个和1799个。
