摘　　要：选取墨玉新旧站2017年逐小时气温、相对湿度、风速3个气象观测要素进行差值分析,同时选择旧站1966—2013年与新站2014—2021年的月平均数据做t检验。结果表明:(1)墨玉新旧站气温、相对湿度和风速差值均呈偏态分布,气温差值分布较分散,仅有38.68%的差值在-1~1℃,相对湿度和风速差值分布较集中,58.91%的相对湿度差值在-10%~10%,79%的风速差值在-1~1 m·s^(-1)。(2)新站平均气温低于旧站,全年平均气温差值为-1.7℃;新站平均相对湿度和平均风速大于旧站,全年平均相对湿度差和平均风速差分别为11%和0.3 m·s^(-1)。(3)经t检验,在0.05的显著性条件下,3种要素均存在断点,需进一步订正。平均气温在1、2、7、9月连续,平均相对湿度在1—3月和10—12月连续,平均风速仅3月连续。The hourly temperature,relative humidity and wind speed in 2017 were selected from the new and old Moyu stations for difference analysis,and the monthly data of old station from 1966 to 2013 and the new station from 2014 to 2021 were used for t-test.The results showed that:(1)The difference of air temperature,relative humidity and wind speed between the old and new weather stations in Moyu was distributed in a skewed way.The temperature difference distribution was relatively scattered,with only 38.68%of the difference between-1~1℃.The relative humidity difference and the wind speed difference were concentrated,with 58.91%of the difference between-10%~10%and 79%of the difference between-1~1 m·s^(-1)(.2)The average temperature of the new station was lower than that of the old station,and the annual mean temperature difference was^(-1).7℃.The average relative humidity and wind speed of the new station were higher than those of the old station,and the annual average difference were 11%and 0.3 m·s^(-1),respectively.(3)The t-test showed that there were breakpoints in all three elements under the 0.05 significance level,which need further correction.The average temperature was continuous in January,February,July and September,the average relative humidity was continuous from January to March and from October to December and the average wind speed was continuous only in March.
