摘　　要：利用温熵图作为热力学图表的特征,简述其在气象中的原理,以温度和湿度基本要素场描述大气的层结结构,并通过图解获取抬升凝结高度、大气稳定度等气象物理量应用于天气预报。结果表明,温熵图在针对强对流天气、冰雪及低能见度天气的预报中有着较好的指示意义,在与数值模式高分辨率输出的结合中发挥更大的作用。This text is based on the Tephigram as the thermodynamics characteristics chart and briefly describes its principle in the meteorology, using basic element for temperature and humidity field describes atmospheric stratification structure, and through the illustration for meteorological parameters such as LCL height, atmospheric stability which applied to the weather forecast. The results show that Tephigram has good instruction to strong convective weather, snowice and low visibility weather forecast, and play a greater role in the combination of numerical model with high resolution output.
