摘要
文章通过整理分析哈尔滨国家高空观测站2019—2023年L波段气象探测资料,对影响探空高度的特殊原因进行了统计研究。结果表明:探空高度受季节和天气系统的影响明显,平均探空高度呈现夏季>秋季>冬季>春季的特点,春季为25545 m,夏季为26852 m。降水天气与非降水天气相比,非降水天气占比为94.17%,平均探空高度为26412 m;降水天气占比为5.83%,平均探空高度为23436 m,两者探空高度相差2976 m。升速方面呈现明显的季节性变化趋势,冬季平均升速快,为444 m·min^(-1),夏季平均升速慢,为417 m·min^(-1);探空高度受观测时次影响不明显。非球炸因素中,探空仪故障会影响探空高度,3种常见探空仪故障中,信号突然消失的情况最多。
By collecting and analyzing the L-band meteorological sounding data from 2019 to 2023 obtained at the Harbin National High-altitude Meteorological Observation Station,a statistical research on the special factors affecting sounding height was conducted.The results indicated that the sounding height was significantly influenced by season and weather systems.The average sounding height followed the seasonal order of summer>autumn>winter>spring,with the height being 25545 meters in spring and 26852 meters in summer.In comparison between precipitating and non-precipitating weather conditions,non-precipitating weather accounted for 94.17%of the cases,with an average sounding height of 26412 meters,while precipitating conditions accounted for 5.83%,with an average sounding height of 23436 meters,showing a difference of 2976 meters between the two.The ascent rate exhibited a clear seasonal variation trend,with the average ascent rate being faster in winter at 444 meters per minute and slower in summer at 417 meters per minute.The influence of observation timing on sounding height was not significant.Among the non-balloon-burst factors,instrument malfunctions of the sounder were found to affect the sounding height,and the sudden signal loss was identified as the most frequent occurrence among three common types of sounder instrument malfunctions.
