防城港市气温与降水南北气候差异分析

Analysis of climate difference between north and south temperature and precipitation in Fangchenggang

分别选取防城港市3个区、县、市(包括防城区、东兴市、上思县)气象站1988~2017年逐月气温和月降水观测资料以及防城气象站1982~2017年和上思气象站1963~2017年的逐日气温资料,并采用数理统计方法对防城港市南北气温、降水、季节差异进行比较,加以分析得出:防城港市地处亚热带季风气候区,受偏南、偏北季风交替影响,十万大山对于防城港市南北气温、降水的差异产生有着明显的地形作用影响。从季节气候特征差异看,南北的夏季季长都趋于增长,但南部的增长效应要明显于北部。

In this paper, the monthly temperature and precipitation data of three meteorological stations in Fangchenggang City （including Fangcheng District, Dongxing City, and Shangsi County） from I988 to 2017, the daily temperature data of Fangcheng Meteorological Station from 1982 to 2017, and the daily temperature data of Shangsi Meteorological Station from 1963 to 2017 were selected, then using mathematical statistics method compared the seasonal difference of the north-south temperature and precipitation of Fangchenggang City. The results indicate that Fangchenggang is located in the subtropical monsoon climate area. Affected by the alternation of the south and north monsoon, Shiwan Mountain has obvious topographic effect on the difference of temperature and precipitation between the north and south of Fangchenggang. From the difference of seasonal climate characteristics, the seasonal length of summer tends to increase both in north and south, but the growth effect in the south is more obvious than that in the north.
