摘要
利用NCEP/NCAR再分析资料等较新资料,从500 hPa高度场、向外长波辐射(OLR)场、海表温度(SST)场以及表征高、中、低纬大气活动特征的14个大气环流指数四个方面,较为系统地研究广东前汛期月降水异常的前期信号,形成预测概念模型,为月降水的量级(即旱、涝、正常)预测提供多方面的信息和实用的预报工具。
Strong signals of monthly precipitation anomaly in Guangdong first raining spell are studied systematically based on the data of atmospheric circulation index and fields of 500 hPa height, out-going longwave radiation (OLR), sea surface temperature (NCEP/NCAR reanalysis data). Conceptual models are formed. Information in many aspects and practical tools are provided for the grades of forecasting (dry, flood or normal) of monthly precipitation.
