L波段电子探空仪系统的探空终止高度受环境温度影响的研究

Research on the influence of ambient temperature on the sounding termination height of L-band electronic sounding instrument system

基于海拉尔区GCOS站2011-2020年L波段电子探空仪系统的探空终止高度的观测数据及该地区这10年的气温观测数据,利用excel统计分析的方法,对每年的探空年平均球炸高度、每年各月的探空月平均球炸高度、每年07时15分与19时15分年球皮质量不达标的数量和10年各月探空仪在高空中出现故障的次数进行统计分析,并与对应时间段内的气温数据进行对比分析。得出结果:电子探空仪系统在每年当中的1、2、3、11和12月份其探空月平均球炸高度基本上均未达到3.5万米以上,其探空仪在高空中出现故障的次数整体偏大,而这几个月份的月平均气温基本上均小于0℃;在每年当中的19时15分年球皮质量不达标的数量均明显高于07时15分的数量,而19时15分球炸时的年平均高空环境温度均明显低于07时15分的温度;低温是影响探空终止高度的关键因素。

Based on the observation data of the sounding termination height of the L-band electronic sonde system of the GCOS station in Hailar District from 2011 to 2020 and the temperature observation data of the area in the past 10 years,using the method of excel statistical analysis,statistical analysis was carried out on the annual average ball blasting height of the sounding in each year,the monthly average ball blasting height of the sounding in each month of each year,the number of ball skin quality that did not meet the standard at 07:15 and 19:15 in each year,and the number of high-altitude sonde failures in each month of the past 10 years,and compared with the temperature data in the corresponding time period.The results are obtained:In January,February,March,November and December of each year,the monthly average ball blasting height of the electronic sonde system did not reach more than 35,000 meters,the frequency of failure of its sonde in high air is generally larger,and the monthly average temperature in these months is basically less than 0℃;At 19:15 each year,the number of ball skin quality that did not meet the standard was significantly higher than that at 07:15,and the annual average high-altitude ambient temperature when the ball is fried at 19:15 is significantly lower than the temperature at 07:15;The ambient temperature is the key factor affecting the sounding termination height.
