| 摘 要： | 云是地球系统的重要组成部分,能够通过影响大气辐射传输,进而影响地气系统的辐射平衡。目前对于三维云场观测得到的信息均具有一定的局限性,需要通过融合分析,综合多源观测资料的优势,得到更为准确的三维云场信息。三维云融合分析业务系统(3DCloudA-V1.0)基于逐步订正方法,融合数值预报产品、静止气象卫星、雷达等多源数据,实时生成0.05°/h分辨率、覆盖中国及其周边地区(0°~60°N、70°~140°E)的三维云融合分析产品,并通过国内气象通信系统将产品下发至全国气象部门;系统采用模块化的系统框架,开发了EC-Flow调度进程实时监测与自动重启等容错功能,有效地提升了稳定性和可靠性。评估结果表明,通过融合多源观测资料,三维云融合分析产品能够对云顶、云中和云底信息进行更为准确的描述。

| Abstract: | Clouds are an important part of the earth system,which can affect the radiation balance of the earth-atmosphere system by affecting atmospheric radiation transmission.At present,the information obtained from three-dimensional cloud observation has certain limitations,so it is necessary to obtain more accurate three-dimensional cloud information by using multi-source observation data merging analysis.Based on the successive correction method,the Three-Dimensional Cloud Merge Analysis Operation System(3DCloudA-V1.0)integrates multi-source data such as numerical forecast products,geostationary meteorological satellite observation,meteorological radar observation to produce the real-time 0.05°/h three-dimensional cloud merging analysis product covering China and its surrounding areas(0°-60°N,70°-140°E),which is distributed to the national and provincial meteorological departments through the China Telecommunication System.The modular system framework is considered in the operation system design and construction process,and the fault tolerant functions such as EC-Flow scheduling process real-time monitoring and automatic restarting are developed,which effectively improves the stability and reliability of the operation system.Evaluations show that through merging multi-source observation data,the three-dimensional cloud merge analysis product can describe cloud the top,inside and bottom information more accurately. |
