摘要
本文采用集合数值模拟方法分析了人工降雨试验的影响。本次研究的重点是2022年10月4日在江原道永东海域附近的东海上空进行的飞机播种试验。采用参数化的气象研究与预报(WRF)模型来反映吸湿性播种材料的效果。测定了国产氯化钠(NaCl)粉体的粒度分布,并将其纳入模型。构建了50个集合成员(播种开始时间腿)来计算播种诱导降水的概率,并以此来分析降水效率。结果表明,受东北风影响,播种材料主要向江原道永东和永西地区扩散。在北江陵(BGN)、江陵城山(GNSS)和大关岭(DGY), 6 h (14:00-20:00 KST)累积模拟降水增强分别为2.7、4.4和0.9 mm。降水离子成分分析证实,BGN站点与播种材料相关的离子明显增加,根据基于集合的分析,种子诱导降水的概率为98%。种子诱导降水概率高的地区降水增加,在概率为100%的地区,效率分别为19.63%(中位数)和23.50%(平均)。降水效率最高的区域出现在海拔1000 ~ 1200 m,与播种高度(海拔约1.5 km)和成云高度一致。
Effect of Airborne Cloud Seeding on Precipitation through Ensemble Numerical Modeling in the Yeongdong Region of Korea
In this study, the effects of cloud seeding experiments were analyzed using ensemble numerical modeling. This study focuses on an aircraft seeding experiment conducted over the East Sea near the Yeongdong region of Gangwon Province on October 4, 2022. The weather research and forecasting (WRF) model was applied with parameterization to reflect the effects of hygroscopic seeding materials. The particle size distribution of domestically produced sodium chloride (NaCl) powder was measured and incorporated into the model. Fifty ensemble members (seeding start time legs) were constructed to calculate the probability of seeding-induced precipitation, which was then used to analyze the precipitation efficiency. The results showed that seeding materials were primarily dispersed to the Yeongdong and Yeongseo regions of Gangwon Province due to northeasterly winds. The 6-h (14:00–20:00 KST) cumulative simulated precipitation enhancement was 2.7, 4.4, and 0.9 mm at Bukgangneung (BGN), Gangneungseongsan (GNSS), and Daegwallyeong (DGY), respectively. Analysis of the precipitation ion components confirmed a distinct increase in seeding material-related ions at the BGN site, corresponding to 98% probability of seeding-induced precipitation, as per ensemble-based analysis. Areas with a high probability of seeding-induced precipitation exhibited increased precipitation, with an efficiency of 19.63% (median) and 23.50% (mean) in the 100% probability zones. The highest precipitation efficiency occurred at altitudes of 1000–1200 m above sea level, aligning with the seeding altitude (approximately 1.5 km above sea level) and cloud formation height.
期刊介绍:
The Asia-Pacific Journal of Atmospheric Sciences (APJAS) is an international journal of the Korean Meteorological Society (KMS), published fully in English. It has started from 2008 by succeeding the KMS'' former journal, the Journal of the Korean Meteorological Society (JKMS), which published a total of 47 volumes as of 2011, in its time-honored tradition since 1965. Since 2008, the APJAS is included in the journal list of Thomson Reuters’ SCIE (Science Citation Index Expanded) and also in SCOPUS, the Elsevier Bibliographic Database, indicating the increased awareness and quality of the journal.
