临河2016年夏季探空资料高度异常分析

Height anomaly analysis of the sounding data from the summer 2016 in Linhe

临河高空站是内蒙古10个非GCOS探空站中唯一使用南京大桥机器有限公司探空仪的台站,针对2016年6—8月探空高度异常情况,进行数据分析,并参照气象气球行业标准中的最大气球爆破直径,计算气球升空高度,得出,临河站存在探空高度普遍偏高的情况,2016年6—8月>36km的探空高度占比为47.2%,全月>38km的探空高度占比为23.4%;探空终止瞬间气压高度和计算所得雷达观测高度相比较,在30km以上,存在平均>3502m的高度差,也存在差值异常偏大的情况。

Linhe’s sounding station is the only one of the non-GCOS sounding stations that uses radiosonde of Nanjing Bridge Machinery Co.,Ltd.in Inner Mongolia.This paper analyzes the data from June to August2016,especially for the analysis of anomalies of sounding height.According to meteorological industry standards in the largest balloon blasting diameter,this study calculates and examines the lift height of the balloon.The results indicated that the sounding height of the Linhe station is generally higher than the normal state.More specifically,from June to August in2016,the sounding height is greater than36KM accounted for47.2%,the full month sounding height greater than38KM sounding height accounted for23.4%.When the altitude of the sounding is higher than30M,comparing the height difference between the sounding height and the calculated radar height,which is larger than3502M on average,this study discovers the difference is also abnormal great.
