New tropical cyclone analysis technique by JTWC

The Joint Typhoon Warning Center (JTWC) has implemented the Dvorak technique as the most important analysis technique for tropical cyclones of the Western Pacific Ocean, the Southern Pacific Ocean, and the Indian Ocean since 1987. On April 1, JTWC is to announce that a new analysis technique is being tested, entirely different from the Dvorak technique.

“The analysis technique is revolutionary as it is based on how beautiful a tropical cyclone is; in addition, we redefine the future of TC analysis,” said JTWC Satellite Analyst SSgt. Cheyenne Lembke. “As a woman who is confident about her own beauty, I feel privileged to introduce this technique regarding to the nature beauty.”

The technique, labeled as LEMBKE (Light Estimating Method Based on Kinetic Evolution), is currently under development, although some of the unique features have been determined. Like the Dvorak technique, LEMBKE is still based on the evolution of a tropical cyclone on satellite imageries, but LEMBKE focuses on the shape of a tropical cyclone. For instance, the golden ratio, a common phenomenon in the nature, is applied to the relationship of a tropical cyclone’s eye and convective ring. The smoothness of the cloud tops, the overall shape of outer bands, the roundness of the eyewall as well as the cyclone itself, etc., are also the backbone of LEMBKE.

“We will not end the Dvorak technique. It will remain a technique used by JTWC, but LEMBKE will dominate over the half of processes regarding to analyzing the intensity of a tropical cyclone. We believe that LEMBKE is the more economical method among various analysis techniques in the future,” said JTWC Satellite Analyst Tech Sgt. Matthew Drew.

联合台风警报中心提出新的热带气旋强度分析法

联合台风警报中心(以下简称JTWC)从1987年起将德沃夏克分析法作为在西北太平洋、南太平洋及印度洋的热带气旋分析的最重要方式。在四月一日,JTWC公布了一个和德沃夏克分析法完全不一样的分析法正在被测试。
“新的分析法是一场革新,因为它基于热带气旋的美观度。进一步说,我们重定义了热带气旋分析的未来。”JTWC的卫星图像分析员,空军上士Cheyenne Lembke说。“作为一位对自己的美丽非常自信的女子,我很荣幸来介绍这个赞扬自然之美的分析法。”

这个名叫LEMBKE(全称Light Estimating Method Based on Kenitic Evolution,基于动力学演化的简易估计法)的分析法目前仍在开发当中,不过其中的一些特性已经被确定。和德沃夏克分析法一样,LEMBKE仍然基于热带气旋的卫星图像变化,但LEMBKE更加注重热带气旋的形状。比如,黄金比,自然界中的一个常见现象,被认为是风眼和对流环的关系。云顶的平滑程度、外围螺旋雨带的总体形状、眼墙和气旋本身圆滑度、等等都是LEMBKE的主心骨。
“我们不会停止德沃夏克分析法的使用,但是LEMBKE会成为超过半数的热带气旋的分析过程。我们相信LEMBKE是在未来是多种分析法里较为经济的一种。”JTWC的卫星图像分析员,空军中士Matthew Drew说道。
