MHD Forecasting of Solar Wind With Coronal Mass Ejections
Space Weather, Volume 23, Issue 12, December 2025.Abstract We present a model, implemented as an online service, for predicting the speed and density of solar wind in the inner heliosphere and near Earth. The model is based on a numerical magnetohydrodynamics code PLUTO. The inner boundary maps are continuously obtained from the National Centers for Environmental Prediction, where they are updated 1 ...

Automated real time detection of solar wind shocks and consequences for the identification of SSC and SI events [PDF]
, 2005 Algorithms have been developed to automatically detect Earth bound shocks in the solar wind as measured by the ACE satellite. These involve simple threshold techniques and wavelet analysis.

Space storms as natural hazards [PDF]
, 2008 Eruptive activity of the Sun produces a chain of extreme geophysical events: high-speed solar wind, magnetic field disturbances in the interplanetary space and in the geomagnetic field and also intense fluxes of energetic particles.

Development of an Electromagnetic‐Thermal Circuit Model for Single‐Phase Three‐Limb Transformers
High Voltage, Volume 10, Issue 6, Page 1545-1557, December 2025.ABSTRACT Analysing the heat states of transformers under DC bias requires careful consideration of their own structural and material characteristics. Although the 3D finite element method (FEM) is a reliable way of simulating all the details of transformers, it may be time‐consuming or have encountered convergence difficulties due to the complex ...

Journal of Geophysical Research: Space Physics, Volume 130, Issue 11, November 2025.Abstract The significant decrease in the global horizontal geomagnetic field is a key indicator of global magnetic storms and serves as the fundamental basis for deriving traditional disturbance storm‐time indices in space weather monitoring. The disturbance intensity varies across regions and with magnetic local time, highlighting the need for more ...

Omega Bands as a Source of Large dB/dt in the Dawn Sector
Journal of Geophysical Research: Space Physics, Volume 130, Issue 11, November 2025.Abstract Omega band activity has the potential to cause geomagnetically induced currents as they can cause large values of dB/dt $\mathrm{d}B/\mathrm{d}t$. We have undertaken a multi‐instrument study of an omega event which occurred from 13 to 14 November 2012, during a period of southward IMF. Measurements from the European Incoherent SCATter (EISCAT)
