[ Method] Based on the ground data, radar data, numerical report data, encrypted automatic station and NCEP reanalysis data, the heavy rain process by tropical storm ＂ Meari＂ was ana- lyzed.

The low-level southeast jet by ＂Meari＂ provided full water trans- mission and layer unstable conditions.

However, little attention has been given to evaluating the suitability and potential of ice-and-snow tourism in poverty-stricken areas. Taking 832 poverty-stricken counties in China as samples, this study proposed an integrity suitability index (ISI) based on natural and socioeconomic factors to evaluate the suitability and potential of developing ice-and-snow tourism in poverty-stricken counties. The results showed that there are significant differences between the spatial distributions of the suitability of glacier- and ski-related tourism. The former is mainly distributed in the Qinghai‒Tibet Plateau, while the latter is distributed in low-altitude mountainous areas. Additionally, 36.0% of the total number of poverty-stricken counties have the potential to match medium-to high-level ISIs of ice-and-snow tourism, of which 2.5%, 32.9% and 0.2% are suitable for glacier excursions, ski sports and both, respectively. Furthermore, climate change and environmental protection are the main constraints on the development of ice-and-snow tourism and corresponding development strategies are proposed. This study can provide references for scientific planning and policy making regarding the sustainable development in poverty-stricken areas.展开更多
