A One‐Year‐Long Evaluation of a Wind‐Farm Parameterization in HARMONIE‐AROME

Journal of Advances in Modeling Earth Systems, 2022
The need to mitigate climate change will boost the demand for renewable energy and lead to more wind turbines both on‐ and offshore. In the near future, the effect these wind farms have on the atmosphere can no longer be neglected.

Wind-Turbine and Wind-Farm Flows: A Review [PDF]

Boundary-Layer Meteorology, 2019
AbstractWind energy, together with other renewable energy sources, are expected to grow substantially in the coming decades and play a key role in mitigating climate change and achieving energy sustainability. One of the main challenges in optimizing the design, operation, control, and grid integration of wind farms is the prediction of their ...

Recent Advances in Laser‐Induced Graphene‐Based Gas Sensors: From Sensing Mechanisms to Biomedical Applications

Advanced Science, EarlyView.
Laser‐induced graphene (LIG) provides a scalable, laser‐direct‐written route to porous graphene architecture with tunable chemistry and defect density. Through heterojunction engineering, catalytic functionalization, and intrinsic self‐heating, LIG achieves highly sensitive and selective detection of NOX, NH3, H2, and humidity, supporting next ...

The Faraday Scalpel: Electrochemical Nerve Lesioning Mechanisms Studied in Invertebrate Models

Advanced Science, EarlyView.
Direct‐current produces nerve lesioning through discrete electrochemical reactions. Using hypoxia‐sensitive locust nerves and hypoxia‐tolerant leech nerves, we map three injury pathways: cathodic oxygen reduction, cathodic alkalization, and anodic chloride oxidation. These findings establish electrochemical lesioning—the “Faraday Scalpel”—as a precise,

Optimization of turbine design in wind farms with multiple hub heights, using exact analytic gradients and structural constraints

Wind Energy, 2019
Wind farms are generally designed with turbines of all the same hub height. If wind farms were designed with turbines of different hub heights, wake interference between turbines could be reduced, lowering the cost of energy (COE). This paper demonstrates

Climate Change Agricultural Comparative Advantage and the US Trade Balance

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT Current science indicates that warming and elevated atmospheric CO2 will have ambiguous results for crop productivity depending on crop type and geographic location, whereas increased heat stress makes livestock and human labor less productive.

Did the Indian Green Revolution Change the Farm Size–Productivity Relationship?

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT We examine the relationship between farm size and productivity during India's Green Revolution, a period of rapid technological transformation. Using a unique panel of over 5000 Indian farm households that spans the Green Revolution (1971–1999), we show that the classic (linear) inverse farm size–productivity relationship gradually evolved ...

Dynamic Strategies for Yaw and Induction Control of Wind Farms Based on Large-Eddy Simulation and Optimization

, 2018
In wind farms, wakes originating from upstream turbines cause reduced energy extraction and increased loading variability in downstream rows. The prospect of mitigating these detrimental effects through coordinated controllers at the wind-farm level has ...
