摘要

关于热带气旋重新进入海洋或形成“海洋”的研究一直很有限。这里，理想化的模拟被用来研究航海热带气旋的再强化。它们遵循一个快慢两个阶段的过程，主要由表面摩擦的变化驱动，然后由加热驱动。先前的陆地退化导致海上热带气旋规模更大，强度更慢，内核收缩比仅在海洋中的情况更温和。尽管如此，它们达到了相同的强度，但综合动能几乎是前者的两倍，因此，海上热带气旋的第二次登陆可能会造成更大的破坏，因为它们的破坏性风的足迹更大。

Re-Intensification of Seafalling Tropical Cyclones

The study of tropical cyclones re-entering the ocean or making ‘seafall’ has been limited. Here, idealised simulations are used to study the re-intensification of seafalling tropical cyclones. They follow a two-stage fast-slow process driven predominately by a change in surface friction initially and then by heating. The previous land decay causes seafalling tropical cyclones to be larger and intensify more slowly with milder inner-core contraction than in ocean-only cases. Nonetheless, they reach the same intensity but with almost twice the integrated kinetic energy, so that the second landfall made by seafalling tropical cyclones can cause more damage due to their larger footprint of destructive wind.

期刊介绍： Atmospheric Science Letters (ASL) is a wholly Open Access electronic journal. Its aim is to provide a fully peer reviewed publication route for new shorter contributions in the field of atmospheric and closely related sciences. Through its ability to publish shorter contributions more rapidly than conventional journals, ASL offers a framework that promotes new understanding and creates scientific debate - providing a platform for discussing scientific issues and techniques. We encourage the presentation of multi-disciplinary work and contributions that utilise ideas and techniques from parallel areas. We particularly welcome contributions that maximise the visualisation capabilities offered by a purely on-line journal. ASL welcomes papers in the fields of: Dynamical meteorology; Ocean-atmosphere systems; Climate change, variability and impacts; New or improved observations from instrumentation; Hydrometeorology; Numerical weather prediction; Data assimilation and ensemble forecasting; Physical processes of the atmosphere; Land surface-atmosphere systems.
