Nowcasting geoelectric fields in Ireland using magnetotelluric transfer functions
Journal of Space Weather and Space Climate, 2023 Geomagnetically induced currents (GIC) driven by geoelectric fields pose a hazard to ground-based infrastructure, such as power grids and pipelines. Here, a new method is presented for modelling geoelectric fields in near real time, to provide valuable ...

Magnetic local time (MLT) dependence of auroral peak emission height and morphology [PDF]
Annales Geophysicae, 2022 We investigate the bulk behaviour of auroral structures and peak emission height as a function of magnetic local time (MLT). These data are collected from the Fennoscandian Lapland and Svalbard latitudes from seven identical auroral all-sky cameras (ASC)

Electron density in the solar corona from type III radio bursts
Proceedings of the Mongolian Academy of Sciences, 2020 It has been proven that electron density in the solar corona is determined by observing the frequency drift of type III radio bursts. We investigated the certain dependence of the scale height on the distance, which allows us to obtain different ...

The Variation of the X-ray Solar Flare’s Time Profile
Universe, 2022 We have studied the variation of the time profile of X-ray emission of solar flares that occurred during the second half of solar cycle 23 (SC 23) and for about the full solar cycle 24 (SC 24) (2002–2018). We define a new index, called the “ratio index” (

Influence of atmospheric stratification on the integral scale and fractal dimension of turbulent flows [PDF]
Nonlinear Processes in Geophysics, 2016 In this work the relation between integral scale and fractal dimension and the type of stratification in fully developed turbulence is analyzed. The integral scale corresponds to that in which energy from larger scales is incoming into a turbulent regime.
