利用技术降低海面温度的提议已经受到关注，因为它可能会在热带气旋登陆前减弱。在这里，应用海洋混合的最大潜在强度理论发现，在高海表温度和深海混合层环境下，人工海洋冷却可以大大削弱热带气旋，特别是在风暴运动速度快的情况下。相比之下，现实的中尺度数值模拟显示，在最理想的大气和海洋条件下，人工冷却的海水可以在热带气旋登陆前两天使其减弱15%，这里评估的最大区域包括2.1 × 104km2的体积和2.6 × 105km2的表面积。因此，基本理论提供了一个无法达到的上限，即使花费大量的资源也无法达到。
Proposals to use technology to cool sea surface temperatures have received attention for the potential application of weakening a tropical cyclone ahead of landfall. Here, application of an ocean-mixing aware maximum potential intensity theory finds that artificial ocean cooling could drastically weaken tropical cyclones over high sea surface temperature and deep ocean mixed layer environments, especially for fast storm motion speeds. In contrast, realistic mesoscale numerical simulations reveal that massive regions - the largest evaluated here contains a volume of 2.1 × 104km3and a surface area of 2.6 × 105km2- of artificially cooled ocean waters could weaken a tropical cyclone two days before landfall by 15% but only under the most ideal atmospheric and oceanic conditions. Thus, the fundamental theory provides an unreachable upper-bound that cannot be attained even by expending vast resources.
