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.

加州大学，洛杉矶分校的David Schriver和大气物理研究所的Petr Hellinger之间的INT 001011SCHRIVERTH，PRAGUE，PETR HELLINGER，通过使用数值模拟和高级数据分析，研究了太空等离子中的波浪过程的物理特征。在数值等离子体模拟方法中具有优势的捷克参与者也属于欧洲波浪实验联盟，并从集群II（欧洲航天局的四个卫星项目）为这项工作带来了新的实验数据来源。 美国团队在分析理论和其他数值模拟（包括粒子中的粒子和弗拉索夫代码）方面贡献了专业知识。研究人员希望将他们的实验和模拟数据比较来解释关键区域中观察到的现象，包括太阳风，弓休克，磁尾和磁磁，极性尖和极光区。 他们的协作结果应有助于我们对地球磁层中波和波粒相互作用的基本理解。该大气科学项目以磁层物理学为特征，实现了通过使美国和中欧的专家能够结合互补才能并在具有强大的共同利益和能力的领域共享研究资源来促进科学知识的计划目标。
