TL;DR: In this article, a lattice Boltzmann (LB) method is developed to solve the solid-liquid phase change coupled with natural convection, in which two sets of evolution functions (density evolution function and temperature evolution function) are constructed to simulate fluid flow and heat transfer.

TL;DR: In this article, a methodology is devised to constrain the LCC response observationally using sea surface temperature (SST) as a surrogate for the latent heat flux and moisture gradient.
Abstract: Differences in simulations of tropical marine low-cloud cover (LCC) feedback are sources of significant spread in temperature responses of climate models to anthropogenic forcing. Here we show that in models the feedback is mainly driven by three large-scale changes—a strengthening tropical inversion, increasing surface latent heat flux, and an increasing vertical moisture gradient. Variations in the LCC response to these changes alone account for most of the spread in model-projected 21st century LCC changes. A methodology is devised to constrain the LCC response observationally using sea surface temperature (SST) as a surrogate for the latent heat flux and moisture gradient. In models where the current climate's LCC sensitivities to inversion strength and SST variations are consistent with observed, LCC decreases systematically, which would increase absorption of solar radiation. These results support a positive LCC feedback. Correcting biases in the sensitivities will be an important step toward more credible simulation of cloud feedbacks.

TL;DR: In this article, two years of continuous eddy covariance measurements were used to characterize the seasonal and annual variability of the latent and sensible heat fluxes above a 50-year-old, 33m tall coastal Douglas-fir forest on the east coast of Vancouver Island, Canada.

TL;DR: In this paper, an innovative self-heat recuperation technology was developed for heating and cooling thermal processes, in which not only latent heat but also sensible heat are circulated in a feed−effluent heat exchanger of the thermal process by compressing the effluent stream without any heat addition.
Abstract: An innovative self-heat recuperation technology has been developed for heating and cooling thermal processes, in which not only latent heat but also sensible heat are circulated in a feed−effluent heat exchanger of the thermal process by compressing the effluent stream without any heat addition. Applying this technology to the thermal processes, the amount of energy required was determined using a commercial process simulation tool, PROII. The proposed self-heat recuperation technology, in which the heat of an effluent stream is recuperated and reused for feed stream heating by gas and/or vapor recompression, was found to drastically reduce the energy consumption.

TL;DR: In this paper, the authors integrate the information about water stress into SEBS, one of the surface energy balance models that employ remote sensing (RS) data, through a modified definition of kB −1, the parameter that summarizes the excess aero- dynamic resistance to heat transfer compared to momentum transfer.
