Remote influence of the Atlantic multidecadal oscillation on the autumn surface air temperature in Southwest China

Earth and Planetary Physics
Southwest China (SWC) is one of the major grain-producing areas in China, and the surface air temperature (SAT) during autumn has a substantial influence on grain production and planting.

On the self-similarity of wind turbine wakes in a complex terrain using large eddy simulation [PDF]

Wind Energy Science, 2019
We perform large eddy simulation of flow in a complex terrain under neutral atmospheric stratification. We study the self-similar behavior of a turbine wake as a function of varying terrain complexity and perform comparisons with a flat terrain.

VIRTUAL ROBOT LOCOMOTION ON VARIABLE TERRAIN WITH ADVERSARIAL REINFORCEMENT LEARNING [PDF]

, 2020
Reinforcement Learning (RL) is a machine learning technique where an agent learns to perform a complex action by going through a repeated process of trial and error to maximize a well-defined reward function.

Spatiotemporal Imbalance of Carbon Balance Pressure in Sichuan–Chongqing: Anthropogenic Emissions vs. Vegetation Sinks and Their Explanatory Factors

Earth
Regional green development requires balancing anthropogenic carbon emissions (CEs) with vegetation carbon sequestration (VCS). Using the CASA model and plant photosynthesis equation, we estimated VCS from net primary productivity (NPP) and proposed a ...

Mean gust factors in complex terrain

Meteorologische Zeitschrift, 2004
Gust factors are analyzed for wind speeds greater than 10 m/s in a large set of data from automatic weather stations in the complex terrain of Iceland. The mean gust factors appear to be independent of the static and dynamic stability of the atmosphere ...

Feature-based terrain editing from complex sketches [PDF]

, 2014
We present a new method for first person sketch-based editing of terrain models. As in usual artistic pictures, the input sketch depicts complex silhouettes with cusps and T-junctions, which typically correspond to non-planar curves in 3D.

Bridging the polarimetric structure and lightning activity of isolated thunderstorm cells during the cloud life cycle [PDF]

Atmospheric Chemistry and Physics
Polarimetric structures detected by radar can characterize cloud microphysics and dynamics. Many studies have indicated that differential reflectivity (ZDR) and specific differential phase (KDP) columns, which serve as proxies for updraught strength, are

Autonomous Cargo Transport with Biohybrid Microswimmers Enabled by Light‐Mediated Bacteria‐Cargo Communication

Advanced Materials, EarlyView.
ABSTRACT Biohybrid microswimmers, which integrate the unique mobility and taxis of living cells with the versatility of synthetic cargo, offer exciting opportunities for targeted delivery. However, current biohybrids lack autonomous decision‐making capabilities due to the absence of communication between living and synthetic components. Here, we report
