摘要

摘要 在过去十年中,分辨率不断提高的超级暴风模拟和观测为龙卷风形成的涡旋尺度过程提供了新的见解。本文通过增加第四个阶段,将这些和其他最新发现纳入了现有的三步模型。目的是提供龙卷风形成过程中物理过程的最新清晰图景。具体来说,我们强调了低层风切变和中层气旋对龙卷风潜势的重要性、龙卷风前相对小尺度垂直涡度最大值的组织和相互作用,以及向龙卷风特征流的过渡。基于这些见解,为未来十年提出了指导性研究问题。

Supercell Tornadogenesis: Recent Progress in our State of Understanding
Abstract Over the last decade, supercell simulations and observations with ever increasing resolution have provided new insights into the vortex-scale processes of tornado formation. This article incorporates these and other recent findings into the existing three-step model by adding an additional fourth stage. The goal is to provide an updated and clear picture of the physical processes occurring during tornadogenesis. Specifically, we emphasize the importance of the low-level wind shear and mesocyclone for tornado potential, the organization and interaction of relatively small-scale pre-tornadic vertical vorticity maxima, and the transition to a tornado-characteristic flow. Based on these insights, guiding research questions are formulated for the decade ahead.
