Abstract Space weather effects arise from the dynamic conditions in the Earth's space
environment driven by processes on the Sun. While some effects are influenced neither by …

Magnetohydrodynamics (MHD)-based global space weather models have mostly been
developed and maintained at academic institutions. While the “free spirit” approach of …

Abstract The South Korean meteorological and environmental satellite GEO-KOMPSAT-2A
(GK-2A) was launched into geostationary orbit at 128.2∘ 128.2^∘ East on 4 December …

The time varying conditions in the near-Earth space environment that may affect space-
borne or ground-based technological systems and may endanger human health or life are …

Twenty‐eight geomagnetic storms driven by magnetic clouds or by sheath regions ahead of
interplanetary coronal mass ejections are examined to address the dependence of the driver …

We analyze an isolated substorm on 29 March 2009 observed by the Thermal Emission
Imaging System (THEMIS) and well monitored by ground‐based observatories at and near …

The solar wind couples to the magnetosphere via dynamic pressure and electric field.
Pressure establishes the size and shape of the system, while the electric field transfers …

Using data from WIND spacecraft, we investigated the difference in substorm bulge
development during different types of solar wind flow: solar wind recurrent streams (RS) …

We present results of 131 geomagnetic storm simulations using the University of Michigan
Space Weather Modeling Framework Geospace configuration. We compare the …

Magnetic field and current system changes in Earth's inner magnetosphere during storm
times are studied using two principally different modeling approaches: on one hand, the …
