摘要
利用位于张家口康保的S波段新一代天气雷达,分析2023年2月9日2处火箭增雪作业的雷达回波特征。由此总结了以下经验:人工播撒前需观察作业点周围回波发展情况,确保作业方位对应的火箭射程范围内有一定强度回波;应熟悉火箭弹在各发射仰角对应的催化剂播撒高度,确保催化播撒高度能够达到预期位置;冬春季节张家口层状云降水云高较低,加之海拔较高,火箭作业宜采取最低仰角作业,地面碘化银烟炉是对火箭作业的有效补充;部分区域仍存在雷达扫描盲区,需及时关注降水实况,结合其他多种观测方式,对作业条件进行综合判别。
The S band new generation weather radar located in Zhangjiakou Kangbao is used to analyze the radar echo characteristics of two rocket snow enhancement operations on February 9,2023.Based on this,the following experience can be summarized:Before manual seeding,it is necessary to observe the development of echoes around the operation point to ensure that there is a certain intensity of echoes within the rocket range corresponding to the operation direction.You should be familiar with the catalyst seeding height corresponding to the launch elevation of the rocket,ensuring that the catalyst seeding height can reach the expected position;In winter and spring,the height of stratiform cloud precipitation clouds in Zhangjiakou is relatively low,and the altitude is relatively high,so the lowest elevation angle operation should be adopted for rocket operation.The ground Silver iodide smoke furnace is an effective supplement to rocket operation;Some areas still have radar scanning blind spots,and it is necessary to pay attention to the actual precipitation situation in a timely manner,combined with various other observation methods,to comprehensively judge the operating conditions.
