论文摘要

Kossin等。 (2020年)(在过去的四十年中)成功测试了气候变化模型的预测,这些模型将有条件的热带气旋强度(主要[3-5级]旋风分离的频率除以所有旋风的频率)。然而,发病率的相对比例最高增加发生在3类旋风中。相对比例最高的降低发生在5类旋风中。该推断不是由于测量误差的不同处理。这可能是由于相对稀有类别5旋风的功率较低。

Kossin et al. (2020) successfully test (over the last four decades) the prediction of climate-change models that conditional tropical cyclone intensity (the frequency of major [category 3-5] cyclones divided by the frequency of all cyclones) should increase. Yet, the highest relative proportional increase in incidence occurred in category 3 cyclones. The highest relative proportional decrease occurred in category 5 cyclones. This inference is not due to different treatment of measurement error. It is plausibly due to lower power for relatively rarer category 5 cyclones.
