To understand the impacts of global warming on tropical cyclones (TCs), we compared various TC properties and environmental conditions during the pre‐industrial period with those in a warm climate with quadrupled CO₂ concentration using the Seoul National University Earth System Model Version 0 with a unified convection scheme (SEM0‐UNICON). TCs in warm climate are faster, stronger, and larger with more precipitation but are short‐lived and fewer than those in cold climate. Fewer TCs in warm climate are associated with the decreases in the climatological mean upward flow at 500 hPa (ω₅₀₀) and the increase in saturation deficit at 600 hPa (δ₆₀₀). In contrast, enhanced TC intensity is associated with the increases in sea surface temperature, upward ω₅₀₀, column‐integrated water vapor, convective available potential energy, and horizontal moisture convergence below 700 hPa along TC tracks.

通过新的一般环流模型模拟，热带气候在热带气候中的CO2浓度增加了三倍的热带气旋活动

为了了解全球变暖对热带气旋（TC）的影响，我们使用首尔国立大学地球系统模型版本0将工业前期的各种TC特性和环境条件与CO ₂浓度四倍的温暖气候下的气候条件和环境条件进行了比较。统一的对流方案（SEM0‐UNICON）。与寒冷气候相比，温暖气候下的TC更快，更强，更大，降水更多，但寿命短且数量少。在温暖的气候更少气旋与在500百帕（气候平均上升流的减小相关联的ω ₅₀₀），并在600百帕增加饱和差（δ ₆₀₀）。与此相反，增强TC强度与在海表面温度的增加有关，向上ω ₅₀₀，柱集成水蒸气，对流有效位能，并且低于700百帕水平湿气收敛沿TC轨道。
