| 摘 要： | 在常规观测资料稀少的热带洋面上,卫星云图是监测热带气旋的主要工具。Dvorak技术通过一系列经验规则,将热带气旋在卫星云图中表现出来的云系结构特征及特定的参数同其发展强度联系起来。介绍了利用Dvorak技术估测热带气旋强度的研究背景和原理方法,总结了国内外在该领域的研究进展及其存在的优势和不足,指出Dvorak技术是目前业务化估测热带气旋强度的主要工具,同时展望了该技术未来的发展方向。

| Abstract: | The primary tool in estimating tropical cyclone intensity is to analyze the imagery of meteorological satellites over the vast tropical ocean,where few in situ observations are available.By using a set of empirical rules,the Dvorak technique relates cloud patterns and particular parameters derived from imagery to current tropical cyclone intensity.An introduction is made to the background of the Dvorak Technique and its main methods,and a summary is made of the advancements of the Dvorak technique in both China and other countries besides its advantages and disadvantages in application.It is pointed out that the Dvorak Technique is the main tool in most of the tropical cyclone forecast centers worldwide presently,and the prospects of the Dvorak Technique are also discussed. |
