    Climate Change Impact on Photovoltaic Energy Output: The Case of Greece by Ioanna S. Panagea, Ioannis K. Tsanis, Aristeidis G. Koutroulis, Manolis G. Grillakis

    Published 2014-01-01
    “…The spatiotemporal analysis indicates significant increase in mean annual temperature (up to 3.5°C) and mean total radiation (up to 5 W/m2) by 2100. The performance of photovoltaic systems exhibits a negative linear dependence on the projected temperature increase which is outweighed by the expected increase of total radiation resulting in an up to 4% increase in energy output.…”

    Reduction of Pacific Double‐ITCZ Bias by Convection Parameterization in NCAR CESM2.2 by Xiaoliang Song, Guang J. Zhang

    Published 2025-01-01
    “…The modified convective closure improves the low‐level cloud and shortwave cloud radiative forcing in the southeastern Pacific. However, surface heat flux plays only a limited role in reducing warm SST bias and double ITCZ bias because the impacts of shortwave radiation changes are largely canceled by changes in longwave radiation and latent heat flux.…”

    Perturbations of Dipole Decay Dynamics Induced by Plasmonic Nano-antennas – A Study within the Discrete Dipole Approximation by Stefania D'Agostino, Fabio Della Sala, Lucio Claudio Andreani

    Published 2015-04-01
    “…Due to the excitation of localized surface plasmons, metallic nano-particles behave like optical antennas and are able to convert localized fields into free- propagating optical radiation, and vice versa. Field localization and enhancement induce strong changes on the decay dynamics of dipoles located in the perturbed electromagnetic environment, and these can be faithfully quantified within the framework of classical electromag‐ netism in terms of total, radiative and non-radiative decay rates. …”
