This investigation is a continuation of earlier work concerning the structure and evolution of the large-scale solar magnetic fields and motions. The proposed efforts will concentrate on understanding these structures and their effects on the solar wind and terrestrial environment. Much of this research relies on observations made at the Wilcox Solar Observatory, which this group has operated for more than fifteen years. Several areas of focus include the interior structure and dynamics of the sun via observations of surface motions and helioseismic techniques; study of the relation between the development and effects of solar activity and the large-scale solar magnetic field organization; study of the three dimensional form of the heliospheric magnetic field and its relation to the solar wind and the terrestrial environment. The goal of this research is to understand the evolution of the solar activity cycle by observations and analyses of interior and surface motions and magnetic fields. *** //

这项研究是关于大尺度太阳磁场和运动的结构和演化的早期工作的继续。拟议的努力将集中于了解这些结构及其对太阳风和陆地环境的影响。这项研究在很大程度上依赖于威尔科克斯太阳天文台的观测，该小组已经运营了15年以上。若干重点领域包括：通过观测表面运动和日震技术研究太阳的内部结构和动力学；研究太阳活动的发展和影响与大规模太阳磁场组织之间的关系；研究日光层磁场的三维形态及其与太阳风和地球环境的关系。这项研究的目的是通过对内部和表面运动以及磁场的观察和分析来了解太阳活动周期的演变。*//
