ABSTRACT
Transportation hubs are vulnerable to extreme climate conditions, but predictions of future climate conditions are limited. This research applied CMIP6 simulations for 12 international-level transportation hubs and 23 national-level transportation hubs. To access near-surface temperature and precipitation results, historical simulation and the SSP245 and SSP585 experiments are employed. Based on the simulations, mean, minimal, and maximal temperatures are all projected to increase by about 5°C in the near future (40 years from the present day) and 10°C in the far future (80 years from the present day). Some cities are expected to experience a drastic increase in the maximum precipitation, especially in the far future. Seasonally, both national and regional transportation hubs are expected to have up to 7-degree increases in temperature across seasons, with the strongest effects in Northern cities over the summer and in cities in the middle during winter and fall. In addition, cities along the Changjiang River are expected to have increased precipitation during spring. Those coastal cities in the south will have the largest increase during winter. To sum up, temperature and precipitations changes are intense in most transportation hubs. Measures should be taken to take into account these increases in climate conditions in main transportation hubs to avoid loss.
