2009年6月9日，第二次龙卷风旋转起源验证实验(VORTEX2)捕捉到了一个独特的数据集，它记录了一个孤立的超级单体的整个生命周期中的密集观测，包括它的死亡。这次活动提供了一个难得的机会来探索与超级单体灭亡相关的条件和过程，以及在风暴-环境相互作用的背景下增加我们对超级单体维持的理解。6月9日的目标风暴正好形成在一条准静止边界的凉爽一侧，最初表现出强烈的低层旋转。然而，随着时间的推移，风暴进入了更深的冷空气中，并完全消散。在超级单体生命周期内发射的三次近流入探测表明，低水平对流抑制(CIN)随着时间的推移而增加。然而，也存在一个包含足够的不稳定性和适度抑制的隆起层，这表明对流上升的潜力尚未实现。接近暴风雨的环境是……
AbstractOn 9 June 2009, the second Verification of the Origins of Rotation in Tornadoes Experiment (VORTEX2) captured a unique dataset of dense observations throughout the lifetime of an isolated supercell, including its demise. This event provides a rare opportunity to explore the conditions and processes associated with supercell demise, as well as add to our understanding of supercell maintenance within the context of storm–environment interactions. The target storm on 9 June formed just to the cool side of a quasi-stationary boundary and initially exhibited strong low-level rotation. Over time, however, the storm moved deeper into the cool air and completely dissipated. Three near-inflow soundings launched over the lifetime of the supercell illustrated an increase in low-level convective inhibition (CIN) over time. However, an elevated layer containing sufficient instability and modest inhibition was also present, suggesting an unrealized potential for elevated convection. The near-storm environment a...
