摘　　要：强对流天气的发生发展与大气稳定度、水汽条件、高低空冷暖平流和垂直风场配置等关系密切,而这些信息都可从探空资料中获取。利用百色站加密探空资料,分析了百色站2016年6月14—15日出现的强对流大风天气发生发展过程。结果表明:利用探空资料中新增加的各种图形功能和内容,通过气球运动轨迹可分析该区域大气的运动方向和气流上升或下沉的高度、强弱,为系统未来的发展提供预报依据。使用埃玛图可以分析大气层结特性,判断大气静力稳定性及对流不稳定性;根据风随高度变化曲线图中风的演变情况,辅以自动站、雷达和天气图等资料,为探索利用加密探空资料分析预报强对流天气提供了思路。The occurrence and development of severe convective weather are closely related to atmospheric stability,water vapor conditions,cold and warm advection in high and low altitudes,and vertical wind field configurations,all of which can be obtained from sounding data.Using encrypted sounding data from the Baise station,the development process of strong convective and strong wind weather that occurred from June 14-15,2016 at the Baise station was analyzed.The results indicate that using various newly added graphic functions and contents in sounding data,the movement direction of the atmosphere in the region,as well as the height and strength of the upward or downward airflow,can be analyzed through the trajectory of the balloon,providing a prediction basis for the future development of the system.The use of Emma diagrams can analyze the characteristics of atmospheric stratification,determine atmospheric static stability and convective instability;The use of wind height variation curves to plot the evolution of stroke,supplemented by data from automatic stations,radar,and weather maps,provides ideas for exploring the use of encrypted sounding data to analyze and predict severe convective weather.
