摘　　要：基于人工模拟降雨实验舱技术,开发仿真降水强度及风场变化的实验系统,用于地面气象观测业务培训,使学员亲身体验降雨强度变化以及理解降水与风速、温度之间的定量变化关系。该实验系统建设20 m^(3)的实验舱,由降雨控制与采集、风速控制、温度采集3个子系统构成。降雨强度模拟范围1~6 mm/min,风速0~19.6 m/s范围内5档控制。教学实践显示,该系统可以提高观测业务人员对降雨强度的直观判断能力,了解不同风速对降雨观测的影响、降雨对气温的影响。该系统在室内有限的空间、有限的实验时间内,实现不同风雨强度的组合变化,提供定量化的实验结果,提高培训效率,同时激发学员的学习兴趣,增强培训效果。Based on the technology of artificial rainfall simulation experiment cabin,an experiment system is developed to imitate the real rainfall intensity and wind field change,and is used for ground meteorological observation training.The students can experience the rainfall intensity change and understand the quantitative relationship between precipitation,wind speed and temperature.The experimental system consists of three subsystems:rainfall control and collection,wind speed control and temperature collection.The simulation range of rainfall intensity is 1-6 mm/min,and the wind speed is 0-19.6 m/s.Teaching practice shows that the system can improve the visual judgment ability of observation operators on rainfall intensity,understand the impact of different wind speed on rainfall observation and the impact of rainfall on temperature.In the limited indoor space and limited experimental time,the system can realize the combination change of different wind and rain intensity,provide quantitative experimental results,improve the training efficiency,stimulate the learning interest of students and enhance the training effect.
