摘要
Abstract
高质量和高分辨率的降水产品在天气预报,数值模式模拟和气象防灾减灾方面起着重要的作用.本文利用四川地区高密度的地面降水传感器观测数据,比较CMPAS四种不同时空尺度的降水实况分析产品,评估CMPAS的融合准确性与在四川地区的适用性.研究表明:四种CMPAS降水产品都在四川盆地内精度较高,攀西地区和川西高原次之.随着降水量的增加,产品的误差也随之增加.CMPAS在夏秋两季对降水量高估,在春冬两季对降水量低估.总而言之,CMPAS在四川盆地内与观测数据的融合准确性较高.由于高原地区气象观测站点数量不足且观测数据受复杂地形和气候条件影响较大,CMPAS在高原地区的适用性检验仍需进一步研究.关键词
