The pre-flare structures in the corona are observed in UV spectral lines of ions FeXXIV, FeXXIII, FeXVIII several hours before big solar flares. During a flare the emission of the UV spectral lines in the corona are increased explosively. These phenomena can be used for prediction of solar cosmic rays. Information obtained from the worldwide neutron monitor network and measurements on GOES spacecraft demonstrates unambiguously that solar cosmic rays are generated in solar flares. These phenomena are well described by the solar flare electrodynamical model, created on the basis of the observational data and the numerical magnetohydrodynamic simulation using the initial and boundary conditions, taken from the active regions observation before the flare. It is impossible to exclude that the similar mechanism of particle acceleration is responsible for galactic cosmic rays generation. Now all published mechanisms of cosmic ray generation are based on unproven assumptions. These assumptions are not confirmed by longterm observations. With the modern concept of cosmic rays, a fundamentally important qu...

A 3-D RBF-FD solver for modeling the atmospheric global electric circuit with topography (GEC-RBFFD v1.0)

Abstract. A numerical model based on radial basis functiongenerated finite differences (RBF-FD) is developed for simulating the global electric circuit (GEC) within the Earth's atmosphere, represented by a 3-D variable coefficient linear elliptic partial differential equation (PDE) in a spherically shaped volume with the lower boundary being the Earth's topography and the upper boundary a sphere at 60 km. To our knowledge, this is (1) the first numerical model of the GEC to combine the Earth's topography with directly approximating the differential operators in 3-D space and, related to this, (2) the first RBF-FD method to use irregular 3-D stencils for discretization to handle the topography. It benefits from the mesh-free nature of RBF-FD, which is especially suitable for modeling high-dimensional problems with irregular boundaries. The RBF-FD elliptic solver proposed here makes no limiting assumptions on the spatial variability of the coefficients in the PDE (i.e., the conductivity profile), the right hand side forcing term of the PDE (i.e., distribution of current sources) or the geometry of the lower boundary.
