北部湾低压向热带风暴发展的时空结构分析

Time and Space Structure Analysis of the North Gulf Depression Strengthening to Be Tropical Storm

该文采用天气动力学分析方法，重点探讨北部湾低压向北部湾热带风暴发展的时空条件和物理机制。文章着重讨论了这类过程的高低层形势特征和空间结构，并通过诊断场的计算分析，揭示了这类过程的空间动力场特征和各层的水汽分布特征。

With dynamical analysis,the paper focuses the time and space condition and physics mechanism about the North Gulf depression strengthening to be tropical storm.The upper and lower situation characteristics and space structure are discussed.By means of calculation and analysis of diagnosis field,the results reveal the dynamical field and vapour distribution feature at levels.The viewpoint of the short term forecast of the North Gulf depression strengthening to be tropical storm is given.
