摘要:
利用多元线性回归模型(MLR)、主成分逐步回归分析模型(PCSR)、克里金插值法(Kriging),将青海湖流域及周边区域0.25°分辨率的TRMM 3B43降水数据降尺度至0.01°分辨率,并选取研究区范围内20个气象站点的实测降水数据,利用相关系数(CC)、均方根误差(RMSE)和相对偏差(Bias)对降尺度结果进行评价,以此选取更适用于研究区的降尺度方法。结果表明:(1) 基于 TRMM及3种降尺度方法获取的研究区降水空间分布具有一致性,年均及春、夏、秋季的降水量均表现为北部高,西部及西北部低,而冬季降水量表现为南部与西北部高,中部低。(2) 研究区降水量随着海拔的增高,以3800 m为界整体上呈现先升高后降低的趋势。(3) 精度评价的结果表明,年尺度上的Kriging精度表现最好;在空间上TRMM及3种降尺度数据在东部地区精度最优。在季尺度上,数据精度表现为PCSR>Kriging>TRMM>MLR;在月尺度上,PCSR数据精度最优。(4) 海拔对研究区内TRMM及3种降尺度数据的影响较小,但随着海拔的升高,遥感数据逐渐出现低估降水的现象,其可能原因在于降水的低估与微波降水率反演时对对流性降水的低估有关。综合降水空间分布一致性分析与精度评价,认为PCSR最适合于青海湖流域及周边区域的TRMM 3B43降水数据降尺度方法。
