AST-0808200MarcusJupiter's weather is currently undergoing a great change with multiple eruptions, the appearance of a new red spot, disturbances at, and south of, the equator and a shrinking Great Red Spot. The rapidity of this current upheaval is without precedent. This project will map Jupiter's velocity fields in all regions (except the poles) with errors smaller than five meters per second, which will result in vorticity maps with only 15% uncertainties. The velocity field maps will be made with recently tested automated techniques of measuring cloud motion from satellite images obtained over the last three decades by Voyager, Cassini, Galileo and, more recently, the Hubble Space Telescope. Numerical simulations that include the unobserved atmospheric parameters (vertical stratification, vertical changes in wind speed, and others) will find the 'best fit' choice by a genetic algorithm. The research should lead to a better understanding of both short- and long-term climate change on Jupiter, with possible application even to Earth's climate.As well as training a graduate student and a post-doc in astrophysics, high performance computation, and velocity extraction, the methods developed during this research should be useful for studies of stars. The team is also trying to develop them for bio-engineering, where they show promise for improving motion capture studies.

AST-0808200Marcusjupiter的天气目前正在发生巨大变化，出现了多次爆发，出现新的红色斑点，赤道和南部的骚乱以及一个不断变化的大红色点。 这种电流动荡的速度没有先例。 该项目将在所有区域（极点除外）的木星速度字段绘制误差小于每秒五米的错误，这将导致仅15％不确定性的涡度图。 速度场图将通过最近测试的自动化技术制作，以测量过去三十年来由Voyager，Cassini，Galileo以及最近的Hubble Space望远镜获得的云图像。 包括未观察到的大气参数（垂直分层，风速变化等）的数值模拟将通过遗传算法找到“最佳拟合”选择。 这项研究应该使木星上的短期和长期气候变化都能更好地理解，甚至可能适用于地球的气候。以及培训研究生和天体物理学后的DOC，高性能计算和速度提取，本研究期间开发的方法应适用于恒星研究。 该团队还试图开发它们进行生物工程，在这里他们表现出改善运动捕获研究的希望。
