Solar radiation energy pulsations in a plant leaf

Journal of Environmental Engineering and Landscape Management, 2010
Solar radiation energy is used by vegetation, which predetermines the existence of biosphere. The plant uses 1–2% of the absorbed radiant energy for photosynthesis.

Estimating Precipitating Energy Flux, Average Energy, and Hall Auroral Conductance From THEMIS All-Sky-Imagers With Focus on Mesoscales

Frontiers in Physics, 2021
Recent attention has been given to mesoscale phenomena across geospace (∼10 s km to 500 km in the ionosphere or ∼0.5 RE to several RE in the magnetosphere), as their contributions to the system global response are important yet remain uncharacterized ...

Fluctuations of Energy Flux in Wave Turbulence [PDF]

Physical Review Letters, 2008
We report that the power driving gravity and capillary wave turbulence in a statistically stationary regime displays fluctuations much stronger than its mean value. We show that its probability density function (PDF) has a most probable value close to zero and involves two asymmetric roughly exponential tails.

Influence of Off-Axis Noncanonical Vortex on the Dynamics of Energy Flux

Photonics, 2023
In this article, we analyze the impact of the off-axis noncanonical vortex on the dynamics of 3D energy flux. The results reveal that the properties of energy flux are significantly influenced by the anisotropy parameter σc of the off-axis noncanonical ...

The Characteristics of Land‐Atmospheric Water and Heat Exchange during Soil Freezing‐Thawing Process over the Underlying Surface of the Alpine Grassland in the Source Region of the Yellow River

Gaoyuan qixiang, 2022
The seasonal characteristics of water and heat exchange in the alpine grasslands are significant， and the freezing‐thawing process has an important impact on the land‐atmospheric water and heat exchange.Based on the observation data of the land surface ...

On the properties of energy flux in wave turbulence [PDF]

Journal of Fluid Mechanics, 2022
We study the properties of energy flux in wave turbulence via the Majda–McLaughlin– Tabak (MMT) equation with a quadratic dispersion relation. One of our purposes is to resolve the inter-scale energy flux $P$ in the stationary state to elucidate its distribution and scaling with spectral level. More importantly, we perform a

Evaluating the JULES land surface model energy fluxes using FLUXNET data [PDF]

, 2010
Surface energy flux measurements from a sample of ten FLUXNET sites selected to represent a range of climate conditions and biome types were used to assess the performance of the Hadley Centre land surface model (JULES).

A Numerical Implementation of a Nonlinear Mild Slope Model for Shoaling Directional Waves

Journal of Marine Science and Engineering, 2014
We describe the numerical implementation of a phase-resolving, nonlinear spectral model for shoaling directional waves over a mild sloping beach with straight parallel isobaths.
