Abstract

Tropical cyclogenesis is a complex phenomenon, involving processes across multiple scales, with various theories proposed to explain its mechanisms. This paper provides an up-to-date summary of the established physical mechanisms and controlling factors of cyclogenesis. Understanding the nature of tropical cyclone formation is necessary to improve tropical cyclone forecasts and inform tropical cyclone mitigation strategies targeting early-stage intervention. Despite the disparities among theories, the critical role of persistent, intensified convection in tropical cyclone initiation is universally acknowledged. Therefore, our hypothesis is that interrupting convective development using aerosol injection is a potential strategy for mitigating tropical cyclone formation. Targetted injection of coarse and fine aerosols at the formation stage are two proposed potential approaches for mitigating tropical cyclones. These methods have completely different microphysical effects but each may ultimately interfere with the formation of the nascent cyclone. These potential interventions open new areas of further research, which are important and necessary to establish a solid scientific foundation for cyclogenesis mitigation.

我们能否利用气溶胶缓解热带气旋的形成?作为理论基础的气旋生成和气溶胶效应综述
热带气旋生成是一种复杂的现象,涉及多个尺度的过程,并提出了各种理论来解释其机制。本文对气旋生成的既定物理机制和控制因素进行了最新总结。了解热带气旋形成的本质对于改善热带气旋预报和制定针对早期干预的热带气旋减灾战略非常必要。尽管各种理论之间存在差异,但持续、增强的对流在热带气旋形成过程中的关键作用已得到普遍认可。因此,我们的假设是,利用气溶胶注入来中断对流的发展,是减缓热带气旋形成的一种潜在策略。在气旋形成阶段有针对性地注入粗气溶胶和细气溶胶是两种拟议的缓解热带气旋的潜在方法。这些方法具有完全不同的微物理效应,但最终都可能干扰新生气旋的形成。这些潜在的干预措施开辟了进一步研究的新领域,对于为减缓气旋的形成奠定坚实的科学基础十分重要和必要。

期刊介绍: The journal publishes scientific papers (research papers, review articles, letters and notes) dealing with the part of the atmosphere where meteorological events occur. Attention is given to all processes extending from the earth surface to the tropopause, but special emphasis continues to be devoted to the physics of clouds, mesoscale meteorology and air pollution, i.e. atmospheric aerosols; microphysical processes; cloud dynamics and thermodynamics; numerical simulation, climatology, climate change and weather modification.
