U.S.-Czech Research: Analysis of Waves and Turbulence in Space Plasma

INT 001011施里弗美国-洛杉矶的加州大学的大卫·施里弗和布拉格的大气物理研究所的彼得·海灵格之间的捷克研究项目通过使用数值模拟和先进的数据分析，研究了空间等离子体波动过程的物理特性。在数值等离子体模拟方法方面具有优势的捷克参与者也属于欧洲波浪实验联合会，并从CLUSTER II（欧洲航天局的四颗卫星项目）为这项工作带来了新的实验数据来源。 美国团队贡献了分析理论和其他数值模拟方面的专业知识，包括粒子单元和Vlasov代码。研究人员希望利用他们对实验和模拟数据的比较来解释在关键区域观察到的现象，包括太阳风，弓形激波，磁尾和磁层顶，极尖和极光区。 他们的合作成果将有助于我们对地球磁层中的波和波-粒子相互作用的基本理解。这一以磁层物理学为特色的大气科学项目实现了促进科学知识的方案目标，使美国和中欧的专家能够联合收割机互补人才，并在共同感兴趣和有能力的领域分享研究资源。

INT 001011SchriverThis U.S.-Czech research project between David Schriver of the University of California, Los Angeles, and Petr Hellinger of the Institute of Atmospheric Physics, Prague, examines the physical characteristics of wave processes in space plasmas through use of numerical simulations and advanced data analysis. The Czech participants who have strengths in numerical plasma simulation methods also belong to the European Wave Experimental Consortium and bring a source of new experimental data to this effort from CLUSTER II (a four satellite project of the European Space Agency). The U.S. team contributes expertise in analytical theory and other numerical simulations, including particle-in-cell and Vlasov codes. The researchers expect to draw upon their comparisons of experimental and simulation data to explain observed phenomena in key regions including solar wind, bow shock, magnetotail and magnetopause, polar cusp and auroral zone. Results of their collaboration should contribute to our fundamental understanding of waves and wave-particle interactions in the Earth's magnetosphere. This atmospheric sciences project featuring magnetospheric physics fulfils the program objective of advancing scientific knowledge by enabling experts in the United States and Central Europe to combine complementary talents and share research resources in areas of strong mutual interest and competence.
