Solar Activity and Solar Oscillations [PDF]
Symposium - International Astronomical Union, 1997 Helioseismology provides us with the tools to probe solar activity. So that we can consider how the solar oscillations are influenced by that activity, we first consider the phenomena that we associate with the active Sun. The surface of the Sun is not quiet but shows evidence of convection on a wide range of scales from a few hundred kilometres ...

The effect of colour on the thermal performance of building integrated solar collectors [PDF]
, 2010 The use of solar collectors with coloured absorbers for water heating is an area of particular interest when considering their integration with buildings.

Assessment of the possibility of forecasting hydrometeorological extremes using the solar activity index [PDF]
, 2023 The paper presents the results of research of correlation fields of the relationship between Wolf number and hydrometeorological parameters (air and water temperature, annual precipitation, snow cover height) for a number of points in the western sector ...

The influence of solar wind variability on magnetospheric ULF wave power [PDF]
, 2015 Magnetospheric ultra-low frequency (ULF) oscillations in the Pc 4–5 frequency range play an important role in the dynamics of Earth's radiation belts, both by enhancing the radial diffusion through incoherent interactions and through the coherent drift ...

Transactions of the International Astronomical Union, 1982 This report summarizes research on solar activity over an almost three-year period from January 1, 1979, till the end of June 1981. In preparing this report we respected the advice of the I.A.U. Executive Committee to cover the highlights of work carried out in the field of solar physics relevant to our Commission, and avoiding double work.

Guided filtering for solar image/video processing
Solar-Terrestrial Physics, 2017 A new image enhancement algorithm employing guided filtering is proposed in this work for enhancement of solar images and videos, so that users can easily figure out important fine structures imbedded in the recorded images/movies for solar observation ...

On solar protons and polar cap absorption: Constraints on an empirical relationship [PDF]
, 2004 International audienceA large database of Solar Proton Events (SPE) from the period 1995 to 2001 is used to investigate the relationship between proton flux at geostationary orbit and Cosmic Noise Absorption (CNA) in the auroral zone. The effect of solar

A forecast of solar activity [PDF]
Journal of Geophysical Research, 1945 I WISH to direct attention to the fact that a relatively long period of intensive solar activity seems to be imminent. If this should be the case, the coming years will probably be very suitable for studying possible relations between sunspots and such terrestrial phenomena as are supposed to be allied to solar activity.

Performance of a building integrated photovoltaic/thermal (BIPVT) solar collector [PDF]
, 2009 The idea of combining photovoltaic and solar thermal collectors (PVT collectors) to provide electrical and heat energy is an area that has, until recently, received only limited attention.

Influence of Solar Activity on Water Clusters. Annual Variations 2015-2019 [PDF]
, 2020 The variations of solar activity and distribution of solar energy due to the rotation of the Earth around its axis and around the Sun exert a strong influence on water clusters, as a result of which their chemical reactivity in hydrolytic processes can ...
