Potential intensity (PI) is a metric for climate model evaluation of TC-related thermodynamic conditions. However, PI is utilized usually for assessing basin-wide TC-related thermodynamic conditions, and not for evaluating TC passage to a certain region. Here we evaluate model-simulated PI over the passage of TCs affecting South Korea (KOR PI) as well as the PI over the entire western North Pacific basin (WNP PI) using 25 CMIP5 and 27 CMIP6 models. In terms of pattern correlations and bias-removed root mean square errors, CMIP6 model performances for KOR PI are found to be noticeably improved over CMIP5 models in contrast to negligible improvement for WNP PI, although it is not in terms of normalized standard deviations. This implies that thermodynamic condition on the route of TCs affecting South Korea is likely better captured by CMIP6 models than CMIP5 models.

CMIP5 和 CMIP6 模型模拟的热带气旋通过韩国的潜在强度性能评估

潜在强度 (PI) 是用于评估 TC 相关热力学条件的气候模型的指标。然而，PI通常用于评估整个盆地与TC相关的热力学条件，而不是用于评估TC通过特定区域。在这里，我们使用 25 个 CMIP5 和 27 个 CMIP6 模型评估模型模拟 PI 在影响韩国的 TC (KOR PI) 以及整个西太平洋盆地 (WNP PI) 上的 PI。在模式相关性和去除偏差的均方根误差方面，发现 KOR PI 的 CMIP6 模型性能比 CMIP5 模型显着提高，而 WNP PI 的改进可以忽略不计，尽管它不是在归一化标准偏差方面。
