On the Effect of Large Scale Structures and Turbulence on Solar Eruptive Events: The Cross-Scale Challenge for Space Weather
Alessandro Ippolito, Giuseppe Prete, Nicolas Wijsen +4
Coronal Mass Ejections (CMEs) are among the most powerful drivers of space weather, yet their prediction remains elusive. A fundamental obstacle is the problem's multiscale nature:…
Comprehensive MHD modelling of ten successive CMEs driving a historic geomagnetic storm -- The 2024 Mothers Day event
Shirsh Lata Soni, Anwesha Maharana, Sanchita Pal +1
Interacting coronal mass ejections (CMEs) result in complex heliospheric structures that can dramatically enhance their geoeffectiveness compared to isolated events. A striking exa…
Rotation of flux ropes in the low corona
Brigitte Schmieder, Anwesha Maharana, Jin Han Guo +2
Eruptions of filaments are defined by different parameters, specially, sigmoid handedness and direction of the eruption, which are important parameters for forecasting the geoeffec…
Flare energetics, CME launch and heliospheric propagation for the May 2024 events, as derived from ensemble MHD modelling
Brigitte Schmieder, Jinhan Guo, Guillaume Aulanier +2
Many questions must be answered before understanding the relationship between the emerging magnetic flux through the solar surface and the extreme geoeffective events. The main ing…
Toroidal modified Miller-Turner CME model in EUHFORIA: II. Validation and comparison with flux rope and spheromak
Anwesha Maharana, Luis Linan, Stefaan Poedts +1
Rising concerns about the impact of space weather-related disruptions demand modelling and reliable forecasting of coronal mass ejection (CME) impacts. In this study, we demonstrat…
Validation of EUHFORIA cone and spheromak Coronal Mass Ejection Models
L. Rodriguez, D. Shukhobodskaia, A. Niemela +15
Aims. We present the validation results for arrival times and geomagnetic impact of Coronal Mass Ejections (CMEs), using the cone and spheromak CME models implemented in EUropean H…
Employing the coupled EUHFORIA-OpenGGCM model to predict CME geoeffectiveness
Anwesha Maharana, W. Douglas Cramer, Evangelia Samara +3
EUropean Heliospheric FORecasting Information Asset (EUHFORIA) is a physics-based data-driven solar wind and CME propagation model designed for space weather forecasting and event…
Studying the spheromak rotation in data-constrained CME modelling with EUHFORIA and assessing its effect on the Bz prediction
Ranadeep Sarkar, Jens Pomoell, Emilia Kilpua +4
A key challenge in space weather forecasting is accurately predicting the magnetic field topology of interplanetary coronal mass ejections (ICMEs), specifically the north-south mag…
Toroidal Miller-Turner and Soloviev CME models in EUHFORIA: I. Implementation
L. Linan, A. Maharana, S. Poedts +2
The aim of this paper is to present the implementation of two new CME models in the space weather forecasting tool, EUHFORIA. We introduce the two toroidal CME models analytically,…
Updates on the FRi3D CME model in EUHFORIA
Anwesha Maharana, Karel Plets, Alexey Isavnin +1
A magnetised flux rope model, "Flux Rope in 3D" (FRi3D) is used in the framework of European Heliospheric Forecasting Information Asset (EUHFORIA) for studying the evolution and pr…

Erika Palmerio, Anwesha Maharana, Benjamin J. Lynch +5
We present observations and modeling results of the propagation and impact at Earth of a high-latitude, extended filament channel eruption that commenced on 2015 July 9. The corona…
Magnetic Energy Powers the Corona: How We Can Understand its 3D Storage & Release
Amir Caspi, Daniel B. Seaton, Roberto Casini +12
The coronal magnetic field is the prime driver behind many as-yet unsolved mysteries: solar eruptions, coronal heating, and the solar wind, to name a few. It is, however, still poo…
