摘　　要：利用台湾海峡西岸晴天近地面大气电场、PM_(10)、SO_2、NO_2、CO、NO、NO_X、温度、相对湿度和气压的同步观测资料,对大气电场日变化及其与典型大陆复杂型大气电场的差异进行了研究,并分析了大气电场与各影响因子之间的关系.结果表明:台湾海峡西岸晴天大气电场日变化呈双峰双谷特征,峰值分别出现在4时和10时,谷值分别出现在14时和19时,相比其他区域大气电场的差异性特征,台湾海峡西岸大气电场的日变化与海陆风关系较为密切.PM10、SO_2、NO_2、CO、NO、NO_X、相对湿度和气压与大气电场呈现正相关性,O_3和温度与大气电场呈负相关.By using the synchronous observation data including atmospheric electric field,PM（10）,SO2,NO2,CO,NO,NOX,temperature,relative humidity and air pressure under the clear day near the ground of the west coast of theTaiwan Strait,the differences between diurnal variation of theatmospheric electric field and thetypical complex atmospheric electric field are studied.We also analyze the relationship between the atmospheric electric field and its influencing factors.The diurnal variation of atmospheric electric field under the clear day near the ground of the west coast of theTaiwan Strait shows the characteristics of double peaks and double valleys.The peaks appear at 04：00 and 10：00,and the valley values at 14：00 and 19：00.Compared to the different characteristics of other regional atmospheric electric field,the diurnal variation of theatmospheric electric field in thewest coast of theTaiwan Strait is more closely relatedto sea land breeze.The atmospheric electric field is in a positive correlation with PM10,SO2,NO2,CO,NO,NOX,relative humidity and air pressure and in a negative correlation with O3 and temperature.
