The role and contribution of magnetic fields, characterized via their magnetic flux, to the statistical structuring of the solar atmosphere [PDF]

open access: yesScientific Reports, 2022
The anomalous heating of the solar upper atmosphere is one of the eight key problems in modern astronomy. Moreover, the stratification of the solar atmosphere is an outstanding key-problem in solar physics.

Wave heating of the solar atmosphere. [PDF]

open access: yesPhilos Trans A Math Phys Eng Sci, 2015
Magnetic waves are a relevant component in the dynamics of the solar atmosphere. Their significance has increased because of their potential as a remote diagnostic tool and their presumed contribution to plasma heating processes. We discuss our current understanding of coronal heating by magnetic waves, based on recent observational evidence and ...

Stratospheric influence on the mesosphere–lower thermosphere over mid latitudes in winter observed by a Fabry–Perot interferometer [PDF]

open access: yesAnnales Geophysicae, 2021
In this paper, we study the response of the mesosphere–lower thermosphere (MLT) to sudden stratospheric warmings (SSWs) and the activity of planetary waves (PWs).

Characterization of marine heat waves in the eastern tropical Atlantic Ocean

open access: yesFrontiers in Marine Science, 2023
Marine heat waves (MHWs) can potentially alter ocean ecosystems with far-reaching ecological and socio-economic consequences. In this study, we characterize the MHWs in the eastern tropical Atlantic Ocean with a focus on the Gulf of Guinea (GG).

Theory of Fluid Instabilities in Partially Ionized Plasmas: An Overview

open access: yesFrontiers in Astronomy and Space Sciences, 2022
Partially ionized plasmas (PIP) are essential constituents of many astrophysical environments, including the solar atmosphere, the interstellar medium, molecular clouds, accretion disks, planet ionospheres, cometary tails, etc., where the ionization ...

A simple parameterization of the short-wave aerosol optical properties for surface direct and diffuse irradiances assessment in a numerical weather model [PDF]

open access: yesGeoscientific Model Development, 2014
Broadband short-wave (SW) surface direct and diffuse irradiances are not typically within the set of output variables produced by numerical weather prediction (NWP) models. However, they are frequently requested for solar energy applications. In order to

Correlation between Supergranular Lane Widths and Sunspot Number; A Simple Way to Predict the Amplitude of Sunspot Cycle

open access: yesThe Astrophysical Journal Letters, 2023
The network structure seen in the solar images is the outline of supergranulation, which is the large-scale convection in the Sun with a size of about 30 Mm and a lifetime of 24 hr.
