1961-2020年松花江流域作物生长季降水主模态气候特征及其异常成因分析OACSTPCD
Analysis of the precipitation patterns and causes of anomalies in crop growing season in the Songhua River Basin from 1961 to 2020
选用1961-2020 年5-9 月松花江流域95 站逐日降水观测资料、JRA-55 逐月再分析资料及海表温度资料,分析该地区作物生长季降水主模态气候特征及其异常成因,探讨其形成机制及前兆信号.结果表明:松花江流域作物生长季降水主要存在两类空间模态,即全流域一致型和东西反相型.20 世纪80-90 年代主要模态为全流域一致型,21 世纪前10a以东西反向型为主,近年以全流域一致型为主.降水全流域一致型模态受中高纬系统和低纬系统共同影响,降水东西反…查看全部>>
Daily precipitation observational data from 95 stations in the Songhua River Basin from May to Septem-ber during 1961-2020,monthly JRA-55 reanalysis data,and sea surface temperature data were utilized to analyze the main precipitation patterns and causes of anomalies in crop growing season in this region,and to explore its mechanism and precursor signals.The results showed that there are primarily two spatial modes of precipitation during the crop growing se…查看全部>>
