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…
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…
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…
Modeling a Coronal Mass Ejection from an Extended Filament Channel. II. Interplanetary Propagation to 1 au
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…
Rotation and interaction of the September 8 and 10, 2014 CMEs tested with EUHFORIA
Anwesha Maharana, Camilla Scolini, Brigitte Schmieder +1
Solar coronal mass ejections (CMEs) can catch up and interact with preceding CMEs and solar wind structures to undergo rotation and deflection during their propagation. We aim to s…
Implementation and validation of the FRi3D flux rope model in EUHFORIA
Anwesha Maharana, Alexey Isavnin, Camilla Scolini +5
The Flux Rope in 3D (FRi3D, Isavnin, 2016), a coronal mass ejection (CME) model with global three-dimensional (3D) geometry, has been implemented in the space weather forecasting t…
