一项研究比较了 1987 年至 2006 年 JMA 和 JTWC 数据集中西北太平洋热带气旋的 Dvorak 参数（T 数和 CI 数），以显示两个数据集之间是否存在差异。研究表明，1992-1997年和2002-2005年期间JTWC的Dvorak参数普遍高于JMA的Dvorak参数。 JTWC情况较强的主要原因是“成熟阶段之前的加速强化和成熟阶段之后减弱的缓慢/延迟开始”。
A study to compare Dvorak parameters (T-number and CI-number) for tropical cyclones over the western North Pacific in both JMA and JTWC datasets from 1987 to 2006 is presented to show if there is a difference between two datasets. The study shows that the Dvorak parameters by JTWC are generally higher than these by JMA during the period of 1992-1997 and 2002-2005. The major reasons for stronger cases in JTWC are "faster intensification before the mature stage and slow /delaye dstart of weakening after the mature stage".
