论文摘要
与盛行的知识相反，拉米雷斯·雷耶斯（RamírezReyes）和杨（2021）表明，热带气旋（TCS）可以自发形成，而无需云分辨模型（CRM）模拟中的水分 - 辐射和表面升华反馈。我们问，为什么？ 13个3D云分解模拟表明，在没有辐射和表面 - 升华反馈的情况下，水分传染（MC）的反馈（MC）反馈可以有效地导致自发的TC发生和强化。在MC反馈中，一个狂热的环境有利于新的深对流事件，从而进一步滋润环境，从而导致对流的聚集。 MC反馈对TC起源和强化的影响发生在两个不同的时间尺度上：由于沉降干燥而导致的损害潮湿的短时尺度（几个小时）和长期尺度（17天）。长时间的损害时间尺度表明，MC反馈是与现实世界中TC起源相关的有效过程。
In contrast to prevailing knowledge, Ramírez Reyes and Yang (2021) showed that tropical cyclones (TCs) can form spontaneously without moisture-radiation and surface-flux feedbacks in a cloud-resolving model (CRM) simulation. Here we ask, why? Thirteen 3D cloud-resolving simulations show that the moisture-convection (MC) feedback can effectively lead to spontaneous TC genesis and intensification in the absence of radiative and surface-flux feedbacks. In the MC feedback, a moister environment favors new deep convective events that further moisten the environment, leading to aggregation of deep convection. The impact of the MC feedback on TC genesis and intensification occurs in two distinct time scales: a short time scale set by detrainment moistening the environment (a few hours) and a long time scale (17 days) due to subsidence drying. The hours-long time scale of detrainment suggests that the MC feedback is an efficient process relevant to TC genesis in the real world.
