Atmospheric Research:多源格点降水资料在西北干旱区的系统评估
yaozi824 2020-2-15 19:30
多源格点降水资料在西北干旱区的系统评估研究 基于多源格点降水资料,以观测资料为基础,从气候学、季节性、年际变化、长期趋势和时空结构等方面,对多源降水数据集在中亚干旱区东部(西北干旱区)降水变化研究中的应用进行系统性评估,涉及的多源降水数据集有 NCEP-1 、 NCEP-2 、 CMAP-1 、 CMAP-2 、 ERA-Interim 、 GPCP 、 CRU 和 MERRA2 数据集。结果表明: ( 1 )多源降水数据均能够合理再现气候态和季节降水的空间分布,相关系数分别大于 0.81 和 0.50 ,均方根误差分别小于 1.17 和 0.63 。 MERRA-2 和 CMAP-2 可以更好地获得气候态空间分析信息,而 CRU 在季节性及时间变化上效果最佳。其中, NCEP-1 、 NCEP-2 和 ERA-Interim 高估了山区的降水量,而 MERRA-2 低估了几乎所有季节的降水量。同样,所有的数据集都很好地再现了年际变异性,其中 MERRA-2 和 CMAP-2 效果最好的。 NCEPs 和 ERA-Interim 的 SD 和 RMSE 均大于其他两组。 ( 2 )在降水的时空模态方面, GPCP 很好地再现了 EOF-1 空间模式和时间变化。 EOF-2 模态反映了干旱区降水东西部的反相分布,所有数据集都反映了东部降水异常的减弱,而 NCEP-2 、 CMAP-2 和 MERRA-2 可以反映帕米尔高原降水的幅度和位置。 CMAP-2 、 ERA-Interim 和 MERRA-2 可以反映 EOF-3 模式的南北反相变化。 ( 3 )卫星遥感融合数据集 ( 如 GPCP 、 MERRA-2 和 CMAP-2) 的表现优于基于观测数据和再分析的数据集。卫星融合产品最大限度地利用了卫星数据和观测数据的优势,提高了未测量地区降水估算的准确性。山区降水的时空异质性较高,使用基于卫星的数据集估算复杂地形地区的降水量还存在一定的困难。因此,需要一个更加完善的观测网络、合理的卫星数据同化、精确的参数化方案和最优的插值方法进行降水估算。 Yao JQ., et al., Evaluation of multiple datasets with gridded precipitation in the arid region of northwestern China, Atmosphere Research,236 (2020) 104818 Gridded precipitation in ARNC--AR-YAO 2020.pdf
