摘　　要：根据收集到的气象、水文资料,通过比较分析进行了青岛冬暖的气象水文学解读,研究表明,青岛冬季比周围的内陆城市温暖,也比周围的沿海城市温暖,其温暖区在沿海南界的范围为日照(石臼所)附近;青岛冬暖表现为在降温后回温更快且升温更高,在周平均尺度上就可以体现出冬暖的特征。青岛冬暖的形成原因是其特定的地理位置和相应的气象水文因子综合而成的,青岛受海水的包绕比较充分,冬季盛行的NW—N向风在造成青岛寒冷的同时也造成青岛周边城市的寒冷,对青岛冬暖有反向衬托作用,也间接导致黄海暖流向青岛近海的补偿性抵近,从而成为青岛冬暖最重要的水动力因子。Hydro-meteorology interpretation on Qingdao＇s warmer winter is carried out through comparison and analysis based on the meteorological and hydrological data collected.The study shows that the winter weather in Qingdao is warmer than those in the surrounding inland and coastal cities.The southern boundary of this warm area along the coast is estimated to be near Rizhao（Shijiusuo）;Qingdao＇s warmer weather in winter is characterized with quick and highly rising in temperature after cooling down.Such a character can be reflected in a weekly averaged scale.It is the specific geographic location and the corresponding hydro-meteorological factors that form Qingdao＇s warmer weather in winter.Qingdao is sufficiently surrounded by sea water,and the prevailing NW-N wind in winter causes cold weather in Qingdao as well as in the surrounding cities,playing a role of a reverse foil for Qingdao＇s warmer weather in winter.However,the Huanghai Warm Current,which comes close to Qingdao offshore as a compensation caused indirectly by the NW-N wind is one of the most important hydrodynamic factors responsible for Qingdao＇s warmer winter.
