摘　　要：该文利用增城国家基准气候站1981—2010年观测资料、地面天气图,对增城的低温天气和影响增城的强冷空气进行了特征分析,并将冷空气分成干冷、湿冷、湿冷转干冷和干冷转湿冷这4种类型,研究不同路径入侵的冷空气对4种类型冷空气过程的影响,发现导致增城区出现低温天气的冷空气活动路径绝大多数是中路,且以干冷为主。该文利用多元线性回归法进一步进行研究,以供参考。Based on the observation data and ground weather map of Zengcheng National Benchmark Climate Station from 1981 to 2010,this paper analyzes the characteristics of low-temperature weather and strong cold air affecting Zengcheng.The cold air is divided into four types:dry cold,wet cold,wet cold to dry cold and dry cold to wet cold.The effects of cold air invaded by different paths on the four types of cold air processes are studied.It is found that most of the cold air activity paths leading to low-temperature weather in Zengcheng District are middle roads,mainly dry and cold.In this paper,multiple linear regression method is used for further research for reference.
