Understanding Solar Cycle Variability [PDF]

open access: yesThe Astrophysical Journal, 2017
Abstract The level of solar magnetic activity, as exemplified by the number of sunspots and by energetic events in the corona, varies on a wide range of timescales. Most prominent is the 11-year solar cycle, which is significantly modulated on longer timescales.

FEATURES OF SHORT-PERIOD VARIABILITY OF TOTAL ELECTRON CONTENT AT HIGH AND MIDDLE LATITUDES

open access: yesSolar-Terrestrial Physics, 2021
The study presents the results of comparative analysis of features of a short-period (with periods of internal gravity waves) variability of total electron content (TEC) in the ionosphere at middle (Novosibirsk) and high (Norilsk) latitudes over a long ...

Solar cycle dependence of scaling in solar wind fluctuations [PDF]

open access: yes, 2008
In this review we collate recent results for the statistical scaling properties of fluctuations in the solar wind with a view to synthesizing two descriptions: that of evolving MHD turbulence and that of a scaling signature of coronal origin that ...

Characterizing Variability of Solar Irradiance in San Antonio, Texas Using Satellite Observations of Cloudiness

open access: yesRemote Sensing, 2018
Since the main attenuation of solar irradiance reaching the earth’s surface is due to clouds, it has been hypothesized that global horizontal irradiance attenuation and its temporal variability at a given location could be characterized simply by ...

Evidence for Solar Modulation on the Millennial-Scale Climate Change of Earth

open access: yesUniverse, 2020
In this study, we use available reconstructed data to investigate periodicities of solar activity (i.e., sunspot number) and the Earth’s climate change (temperatures of Lake Qinghai in China and Vostok in Antarctica, the GISP δ18O climate record of ...

On the correlation of spatial wind speed and solar irradiance variability above the North Sea [PDF]

open access: yesAdvances in Science and Research, 2016
Mesoscale wind fluctuations on a time scale of tens of minutes to several hours lead to high wind power fluctuations. Enhanced mesoscale wind variability emerges during cold air outbreaks and resulting cellular convection.

SORCE‐Based Solar Spectral Irradiance (SSI) Record for Input Into Chemistry‐Climate Studies

open access: yesEarth and Space Science, 2019
Whole atmosphere chemistry‐climate model (CCM) transient studies require a solar spectral irradiance (SSI) time series with very broad wavelength coverage with an uninterrupted daily cadence over a full solar cycle time period.

Mode-based energy storage control approach for residential photovoltaic systems

open access: yesIET Smart Grid, 2018
This study presents a novel mode-based energy storage control approach. Assuming that an energy storage device (ESD) is equipped with a set of predetermined real-time control modes, the dispatch objective is to select an optimal mode instead of a ...
