摘要
利用巴里坤县基本气象观测站2014~2019年逐时气象资料,运用统计分析和方法,对巴里坤县能见度进行分析,结果表明:1) 巴里坤近6年来,1~3月能见度相对偏低,6~9月能见度较好;2) 能见度具有明显的日变化,各季节能见度日变化与日出时间有关;3) 低能见度(小于800 m)出现频率较少,多出现在冬季;清晨和上午易高发低能见度事件;4) 能见度与平均气温、相对湿度、降水日数和平均风速有相关关系;影响巴里坤能见度的天气现象主要有雾、沙尘暴、扬沙、浮尘和雨雪天气。
Based on hourly meteorological data of Balikun County Basic Meteorological Observatory from 2014 to 2019, visibility in Balikun County is analyzed with statistical analysis and methods. The results show that: 1) Visibility in Balikun County is relatively low from January to March in recent 6 years, and much better from June to September;2) Visibility has obvious diurnal variation, which is related to sunrise time in each season;3) Low visibility (less than 800 m) occurs less frequently, mostly in winter;early morning and morning are prone to high incidence of low visibility events;4) Visibility is related to average temperature, relative humidity, precipitation days and average wind speed;weather phenomena affecting visibility in Balikun mainly include fog, sandstorm, sand blowing, floating dust and rain and snow weather.
