Photosynthetic Active Radiation, Solar Irradiance and the CIE Standard Sky Classification
Applied Sciences, 2020 Plant growth is directly related to levels of photosynthetic photon flux density, Qp. The improvement of plant-growth models therefore requires accurate estimations of the Qp parameter that is often indirectly calculated on the basis of its relationship ...

Energy Reports, 2023 Simulator fOr Wind Farm Applications (SOWFA) is a powerful wind farm simulation tool. It is widely used in wake effect research. However, the integration between AI and SOWFA is weak. Without AI, it is difficult for us to fully use SOWFA.

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 ...

Research on participation of flywheel energy storage in wind farm frequency regulation control
Zhejiang dianli, 2022 In view of a whole series of problems such as the reduction of system inertia， the increase of frequency fluctuation， and the deterioration of power quality caused by large-scale wind power integration， a flywheel with high power density is designed for ...

On slow solar wind with high Alfvénicity: from composition and microphysics to spectral properties [PDF]
Monthly notices of the Royal Astronomical Society, 2018 Alfv\'enic fluctuations are very common features in the solar wind and are found especially within the main portion of fast wind streams while the slow wind usually is less Alfv\'enic and more variable.

Solar wind stream interaction regions throughout the heliosphere
Living Reviews in Solar Physics, 2018 This paper focuses on the interactions between the fast solar wind from coronal holes and the intervening slower solar wind, leading to the creation of stream interaction regions that corotate with the Sun and may persist for many solar rotations. Stream

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