Computational and Experimental Simulations of Comet Shoemaker-Levy 1993e Interaction with the Jovian Atmosphere

拟议的研究将使用计算方法模拟预测的苏梅克-列维彗星1993e碎片与木星大气的超高速相互作用。模拟的目的是为其他预测调查提供即时信息，并为观测事件提供指导。将对单个火流星事件进行二维和三维模拟。这些模拟将提供对穿透深度、破碎模式和火流星分散、能量沉积机制和大气不同区域内能量沉积速率的估计，并量化撞击倾角和火流星不规则性的影响。这些结果将尽快提供给大气建模者，以帮助估计潜在的长期可观测特征，如重力波和木星大气中的物质上涌。＊＊＊

9322118 Crawford The proposed research will simulate the predicted hypervelocity interactions of Comet Shoemaker-Levy 1993e fragments with the Jovian atmosphere using a computational approach. The goal of the simulations is to provide immediate information for other predictive investigations and guidance for observations of the event. Two and three-dimensional simulations of the individual bolide events will be made. These simulations will provide estimates of the penetration depth, the mode of fragmentation and bolide dispersion, the mechanism of energy deposition and energy deposition rates within different regions of the atmosphere, and quantify the effect of impact obliquity and bolide irregularities. These results will be made avialable to atmospheric modelers as quickly as possible to aid in estimates of potential long-lived observable features such as gravity waves and material upwelling in the Jovian atmosphere. ***
