Based on the data of tropical cyclones (TCs) in China for 1986-2015,TCs that caused economic losses are defined as hazard-inducing TCs. The threshold of hazard-inducing TCs in southeastern coastal China is determined through observed daily air pressure, wind speed and precipitation data from meteorological stations. Subsequently, the frequency, wind speed and precipitation of hazard-inducing TCs are predicted by the regional climate model COSMO-CLM (CCLM), and their spatiotemporal variations are analyzed under the 1.5 ℃ and 2.0 ℃ warming scenarios relative to the baseline period of 1986-2005. Research results are shown as follows: (1) The frequency of hazard-inducing TCs in southeast coastal China shows an increasing trend from 1986 to 2005. Observed average wind speed and precipitation are 8.7 m/s and 129.8 mm, respectively. The influenced areas are mainly distributed in the east of Zhejiang province and the east coast of Guangdong province. (2) Under the 1.5 ℃ warming scenario of 2020-2039,the frequency of hazard-inducing TCs will increase by 24% relative to 1986-2005, and the increase is mainly distributed in the southwest part of Guangdong and the southern part of Fujian. Meanwhile, wind speed and precipitation by TCs will increase by 15% and 17%, respectivley, which is most significant in the coastal areas of Fujian. (3) Under the 2.0 ℃ warming scenario of 2040-2059, the frequency of hazard-inducing TCs will increase by 33% relative to the reference period of 1986-2005, and wind speed will increase by 32%. Precipitation will increase by 35%, with the neighboring area of coastal Fujian and Guangdong and t he southwest Guangdong having the largest growth rate. (4) With the global temperature increase from 1.5 ℃to 2.0℃,the frequency of hazard-inducing TCs will continue to rise, and the accompanying wind speed and precipitation might also increase by 17% and 18%, respectively. The aforementioned findings revealed that the frequency, wind speed, precipitation and influential area of hazard-inducing TCs in the southeastern coast of China will increase with the rising of temperature. It is significant to control global temperature increase below 1.5 ℃ for reducing the adverse effects of hazard-inducing TCs.
