Research finds tropical cyclone rainfall is extending further inland
What happened
A research team at Hong Kong Polytechnic University analyzed global tropical cyclone and rainfall data spanning 1980 to 2023. The team found that heavy TC rainfall, defined as at least 30 millimetres within three hours, is extending further inland along Northern Hemisphere coasts. This inland shift is occurring at a rate of approximately 3.8 ± 1.8 kilometres per decade and is linked to rising nearshore sea-surface temperature.

Why it matters
The finding indicates that inland regions, which were historically less affected by such events, are facing increased disaster risks. This quantitative analysis addresses a gap in global research regarding the inland extension of TC rainfall and the role of nearshore sea-surface temperature warming.

Who could feel it
Possible knock-on effectsThese are possibilities Brind reasoned out, not predictions, and not advice. Most are not stated in any report.
- Hong Kong Polytechnic UniversitySpeculative
Coastal and inland regions might face increased costs for infrastructure repair and higher insurance premiums due to the expanding reach of heavy rainfall.
