| Summary: | Abstract China is one of the countries most affected by tropical cyclones (TCs) worldwide. However, it remains unclear whether the significant poleward and coastal shifts in global TCs due to climate warming have affected the lifetime of landfalling TCs in China. Result shows that the lifetime of landfalling TCs in China has significantly decreased by 24% over the past 40 years, which is primarily contributed by the minor TCs. The duration in development stage has significantly shortened for both major and minor TCs. The northwestward migration of genesis locations has led to a decrease in duration of minor TCs, while the increase in the intensification rate has contributed to the shorter major TC durations. Further analysis suggests that these changes in TC lifetime and northwestward shifts are associated with a decrease in the Convective Available Potential Energy and westward extension of the subtropical high. The observed increase in rapid intensifications of major TCs is mainly driven by an increase in favourable thermodynamic environments. These findings clarify the connection between large-scale changes in TC genesis locations and regional characteristics of TC activity. |
