摘要
Based on observation data of temperature from automatic meteorological stations in all towns and the national weather station in Guilin City,annual and monthly variations of average temperature,distribution of high-temperature days in Guilin in 2013,and weather situations causing high temperature in Guilin were analyzed.The results showed that in 2013,annual average temperature in Guilin was 1.4℃higher than the multiyear average.The hottest weather occurred in Wenqiao Township,Quanzhou County in the northeast,followed by the urban district and suburbs of Guilin,Lianhua Town of Gongcheng County in the south,Tongan,Zhangjia and Dafa towns of Pingle County,Dongchang and Datang towns of Lipu County.Terrain had distinct effects on regional high temperature,that is,there was no hot weather with daily maximum temperature of≥35.0℃in mountainous areas with an altitude of≥1 200 m;temperature was abnormally high in low-lying areas surrounded by mountains.In addition,the Western Pacific subtropical high pressure was the main weather system leading to hot weather in Guilin.
