Space Weather – Sun Earth Relations

Space Weather Forecast Predicts Changes in Sun-Earth Space Environment by Using Observation Data

Modeling a space weather event from the Sun to the Earth: CME generation and interplanetary propagation

[1] We present a three-dimensional (3-D) numerical ideal magnetohydrodynamics (MHD) model describing the time-dependent expulsion of a coronal mass ejection (CME) from the solar corona propagating to 1 astronomical unit (AU). The simulations are performed using the Block Adaptive Tree Solar-Wind Roe Upwind Scheme (BATS-R-US) code. We begin by developing a global steady-state model of the corona...

Climate and Weather of the Sun - Earth System

For Space Plasmas: Sun-to-earth Simulations

are increasingly essential to basic and applied space-physics research for two primary reasons. First, the heliosphere and magnetosphere are vast regions of space from which we have relatively few in situ measurements. Numerical simulations let us “stitch together” observations from different regions and provide data-interpretation insight to help us understand this complex system’s global beha...

The Sun-earth Space Information System

Nowadays the object of Space Information System (SIS) is limited to the earth surface, and the large-scale sun-earth space does not been considered. In this paper, the research object of SIS is been extended, namely the object is been studied from the earth surface to the sun-earth space, and the concept of “Sun-earth Space Information System” is been proposed. It is the very important content ...
