中文摘要: 收集了湖北省1961—2009年76个站点的逐日温度数据，选择其中通过均一化检验的33个站点作为研究对象，分析了湖北省年极端高温的发生频率、强度变化及对区域性增温的贡献。研究表明：湖北省年极端高温发生频次与海拔高度相关性较好，极端高温发生频次呈东西减少、中部增加的趋势；极端高温发生频率的地理分布一致性较好，江汉平原及东北部易出现极端高温事件；西南部的极端高温强度较弱；极端高温事件的发生频率与夏季平均气温呈正相关，东北部的相关程度较西部显著。
中文关键词: 均一化检验， 极端高温， EOF， 标准化
Abstract:Out of the 76 sites’ daily temperature data in 1961-2009 in Hubei Province, the 33 sites were chosen as a research object by homogenization test. The occurrence frequency of extreme high temperature in Hubei Province, intensity changes and response to the regional warming were analyzed. The results show that, the frequency of extreme high temperature is correlated well with the altitude, and that frequency of extreme high temperature displays decreasing in east and west directions and increasing in central. The spatial distribution in the frequency of extreme high temperature shows better consistency, and extreme high temperature events are prone to take place in Jianghan Plain and its northeast. The frequency of extreme high temperature events is positively responding to the summer mean temperature, and in relation to the western, the northeast response is more significant.
