摘要: 利用2011-2012年盖州市大气能见度和地面气象要素(相对湿度、风速、气温、气压)的观测资料,分析了盖州地区大气能见度月和日的变化特征及大气能见度与气象要素的相关性。结果表明:盖州市大气高能见度事件多出现在3月和10月,低能见度事件多出现在6-8月;夏季能见度最低,14时能见度最大,20时能见度比08时略小。大气能见度与相对湿度相关性最大,与风速和气温相关性次之,与气压相关性最差;当相对湿度>80.0%时,能见度最低值为10.4±3.2 km,大气能见度与气压、气温、相对湿度的相关系数分别为-0.52、0.51和-0.52;其中较高的气温、较大的相对湿度、较小的风速及较低的气压是盖州地区低能见度(<10 km)事件发生的主要气象条件。

Abstract: Based on the observational data of atmospheric visibility and some meteorological parameters (relative humidity,wind speed,air temperature,and atmospheric pressure) at ground from 2011 to 2012 in Gaizhou of Liaoning province,the monthly and daily variations of atmospheric visibility as well as its correlation with meteorological parameters were analyzed.The results show that the high visibility events usually occur in March and October in Gaizhou,and the low visibility ones mostly occur from June to August.The visibility in summer is the lowest during a whole year,and its largest visibility appears at 14:00,lower one at 08:00,and the lowest at 20:00 during a day.The correlation of atmospheric visibility with relative humidity is the best,and followed by wind speed,air temperature,and atmospheric pressure.As relative humidity is larger than 80.0%,the minimum atmospheric visibility is in the range of 10.4±3.2 km,and the correlation coefficients between visibility and atmospheric pressure,air temperature,and relative humidity are -0.52,0.51 and -0.52,respectively.Low visibility events (<10 km) in Gaizhou mainly result from higher air temperature and relative humidity,as well as smaller wind speed and atmospheric pressure.
