“8·12”天津港爆炸事故处置现场人工影响天气保障方案设计与实现

Design and Realization for Artificial Rain Mitigation Operation Service Scheme in Explosion Accident of Tianjin Port

"8·12"天津港特别重大火灾爆炸事故发生后,救援处置工作面临巨大挑战。开展科学施救,避免次生灾害发生和救援人员伤亡,对应急气象保障服务提出了新的挑战,也对人工影响天气工作提出新的要求。通过分析"8·12"天津港特大火灾爆炸事故救援工作对人工影响天气服务的需求,设计人工消减雨试验方案,明确了人工影响天气应急服务关键时间节点的主要工作内容、流程,作业防线布设、时机掌握、催化部位、剂量和方式等技术要点,并对人工影响天气作业保障情况进行评估,试验期间消减雨作业有效率为37.5%,为今后应对突发事件人工影响天气保障服务提供参考。

After the serious fire and explosion accident on August 12, it＇s a great challenge for rescue and disposal works. Scientific rescue could avoid secondary disasters and rescue personnel casualties. Not only emer- gency meteorological service but also weather modification works has met new challenges. Based on the analysis for weather modification works in this severe fire and explosion accident, artificial rain mitigation operation experimen- tal scheme is designed. The major work contents, procedure, arrangement of operation line, operation time, see- ding location, and catalyst dosage and operation mode are all given in this scheme. The weather modification serv- ices are evaluated. Effective percentage of artificial rain mitigation operation is 37.5% during the trial. These works could provide reference for weather modification service of emergencies.
