In this research, we utilized a 3-dimensional (3D) data-driven global full magnetohydrodynamics (MHD) model to thoroughly investigate the formation reason of switchbacks. Through simulations, we propose a possible formation reason: when disturbances in the velocity or pressure of the plasma near the solar surface arise and their intensity and scope surpass a specific threshold, the magnetic field will progressively curve over time, ultimately forming a switchback structure. Furthermore, the magnitude and range of these perturbations directly correlate with the swiftness of the switchback’s formation; the more intense or widespread the perturbations, the quicker the structure will materialize.</p></div>","PeriodicalId":777,"journal":{"name":"Solar Physics","volume":"300 7","pages":""},"PeriodicalIF":2.4,"publicationDate":"2025-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145143934","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Moreover, due to the inability of standard models using microscopic diffusion to reproduce light element depletion in the Sun (Li, Be), another efficient process must be included to reproduce these constraints (rotation-induced: Eggenberger et al. 2022, overshooting -or penetrative convection- below the convective envelope: Thévenin et al. 2017, or ad hoc turbulence: Lebreton and Maeder 1987; Richer, Michaud, and Turcotte 2000).

By combining the eruptive flare model with findings from our magnetohydrodynamic and particle-in-cell simulations, we demonstrate the crucial role of decimetric radio bursts in understanding plasma processes during eruptive flares. We describe unusual drifting continua associated with the rise of a magnetic rope at the onset of these flares. Notably, we report very rare slowly positively drifting bursts (SPDBs) linked to the bright helical structure of the ascending rope. Drifting pulsation structures (DPSs) are identified as signatures of plasmoids, while narrowband decimetric spikes are associated with magnetic reconnection outflows. We also examine pairs of decimetric Type III bursts, which indicate electron beams propagating both upward and downward in the solar atmosphere from the acceleration site, as well as a special Type III burst likely traveling around a plasmoid. We introduce a method for computing period maps and identifying a unique wave/shock feature in the radio spectrum. A movie illustrating the plasma processes responsible for generating the drifting pulsation structure is also shown. The interpretations of all presented bursts are based on the standard model of eruptive flares. However, positional data for sources of these radio bursts are often lacking. To emphasize the importance of spatial information, we present an example of a drifting pulsation structure observed simultaneously with observations from the Expanded Owens Valley Solar Array (EOVSA).
