Reply to: Limitations of reanalyses for detecting tropical cyclone trends

Nature Climate Change volume 14, pages 146–147 (2024)Cite this article

Subjects

The Original Article was published on 20 November 2023

replying to K. Emanuel Nature Climate Change https://doi.org/10.1038/s41558-023-01879-y (2023)

Chand et al.1 demonstrated that tropical cyclone (TC) frequency in the Twentieth Century Reanalysis (20CR) dataset has declined globally and regionally during the twentieth century. Emanuel2 has suggested that the decline is artificial, caused by increasing numbers of surface-pressure observations during this time.
