| 摘 要： | 利用全国气象观测资料、NCEP／NCAR日平均再分析数据资料集和我国高致病性禽流感疫情资料，分析高致病性禽流感发生的时空特征以及与天气条件的关系。结果表明，我国高致病性禽流感全年可以发生，疫情的分布范围广，大部分地区都有出现。发生和传播与环境气象条件有关，季节性明显，冬季和秋季为主要发病季节。冬季禽流感发生前高空500hPa以槽为主，冷空气活动频繁。发生日基本在高压系统的控制之下，地面流场呈辐散状，风速稳定少变。

| Abstract: | By using the national meteorological observation data, the daily NCEP/NCAR reanalysis datasets and the epidemic situation data of highly pathogenic avian influenza （HPAI） in China, the relationship between the spatial and temporal features of HPAI and meteorological conditions was investigated. The results show that HPAI can occur in the whole China, the epidemic situation is of wide distribution, and HPAI can be found in most of China. The happening and propagation of HPAI relates to the weather conditions and owns obvious seasonality. HPAI mainly oc- curs in winter and autumn. Before the outbreak of HPAI in winter, there are almost troughs at 500 hPa, and the activities of cold air are frequently. The high pressure dominates the regions where HPAI happens, the surface flows present the status of divergence and the wind velocity is stable. |
