摘要
根据阿拉水文站2022年人工和自动站的气温观测数据,分析其对比差值发现:①阿拉尔年平均气温对比观测差值0.20℃,即自动站的气温平均比测比人工站高0.20℃。标准差0.60℃,逐日最高、最低自动与人工气温0.60~0.40℃,标准差1.10~1.90℃对短期气温预测,阿拉尔自动气象站观测数据是可用的,就气候研究来说阿拉尔自动站的气温观测数据是可用的;②一年四季中,阿拉尔秋季和冬季的对比差值的绝对值都小于0.20.因而此时阿拉尔自动气象站数据可信可用;春季和夏季对比观测差值的绝对值大于等于0.20气温观测数据是可靠的必须慎重使用。③在一天中,阿拉尔早和晚对比值的绝对值都小,因而自动气象观测数值是完全可信的。
According to the air temperature observation data of artificial and automatic stations of Ala Hydrological Station in 2022,the following three points are found by analyzing the comparative difference.First,the annual average temperature difference of Alar is 0.20℃,which means the average temperature of automatic stations is 0.20℃higher than that of manual stations.The standard deviation is 0.60℃,with daily highest and lowest automatic and artificial temperatures ranging from 0.60 to 0.40℃.The standard deviation is 1.10 to 1.90℃.For short-term temperature prediction,the observation data from the Alar automatic meteorological station is available.In terms of climate research,the temperature observation data from the Alar automatic meteorological station is available.Second,in the four seasons of the year,the absolute value of the contrast difference between Alar autumn and winter is less than 0.20.Therefore,the Alar automatic weather station data are reliable and available at this time.When the absolute difference between spring and summer observation is greater than or equal to 0.20,the temperature observation data are reliable and must be used carefully.Third,during a day,the absolute values of Alar’s morning and evening contrast difference are small,so the automatic meteorological observation values are completely reliable.
