摘　　要：采用NASA HS3飞机下投式探空仪资料、ERA-Interim再分析资料、FNL再分析资料,和NPP ATMS卫星反演资料获得的飓风Edouard(2014)的数据,分别计算飓风中心附近的温度距平。再用所得值分别绘制飓风中心多种结构图。将4种数据同种图样对比,分析飓风Edouard(2014)暖心结构,对比各种资料。得出结论:在热带气旋暖心结构的研究中,飞机下投式探空仪采样机会受到诸多限制。ERA-Interim再分析资料可估算暖心面积;FNL再分析资料可确定暖心经纬度位置、最大温度距平所在高度和各层暖心偏移程度;NPP ATMS卫星观测资料能提供更多观测信息用于资料同化,便于对暖心结构进行精细化分析。The dropsonde data of NASA HS3 aircraft, ERA-Interim reanalysis data,FNL reanalysis data, and the data of Hurricane Edouard(2014) obtained from NPP ATMS satellite inversion data were used to calculated the temperature anomaly near the hurricane center. Then, the obtained values were used to draw various structural diagrams of hurricane centers respectively. Compared the same pattern of four data, analyzed the warmcore structure of Hurricane Edouard(2014),and compared the data. Conclusion: In the research of tropical cyclone warm-core structure, there were many limitations in the sampling opportunity of aircraft dropsonde.ERA-Interim reanalysis data can estimate the warm core area;FNL reanalysis data can determine the latitude and longitude position of warm core, the height of maximum temperature anomaly and the degree of warm core deviation in each layer. The observation data of NPATMs satellite can provide more observation information for data assimilation,which is convenient for fine analysis of warm core structure.
