Rare Lightning and Convection Characteristics During Two Successive Tornadoes in Southern China

High Voltage, EarlyView.
ABSTRACT Systematic investigations into lightning characteristics of tornado storms in China remain scarce. This study comprehensively analyses rare lightning behaviour and overshooting top characteristics for two successive tornadoes during a long‐lived supercell in southern China on 27 April 2024.

Flow Induced by Dual-Turbine of Different Diameters in a Gas-Liquid Agitation System: the Agitation and Turbulence Indices [PDF]

, 2006
Flow induced by a dual turbine stirred tank was characterized measuring local velocities with a LDV and drawing the main velocity fields and the maps of turbulence intensities.

Evidence of Terrain-Induced Windshear Due to Lantau Island over the Third Runway of the Hong Kong International Airport—Examples and Numerical Simulations

Applied Sciences
The new third runway of the Hong Kong International Airport was commissioned in November 2022. With the increased distance away from the mountains of Lantau Island to its south, it is not certain if terrain-induced windshear could still happen over the ...

Review of Catenary Icing on High‐Speed Railways: Characteristics, Impact and Countermeasures

High Voltage, EarlyView.
ABSTRACT The pantograph–catenary system (PCS) is the only path for electrified railway trains to acquire energy. Catenary icing during winter is a common natural phenomenon, which usually leads to the deterioration of the current quality and severely affects the operational safety of trains.

Conceptual colour: race, economic knowledge, and the anthropology of financialization De la couleur comme concept : race, connaissances économiques et anthropologie de la financiarisation

Journal of the Royal Anthropological Institute, EarlyView.
Economic anthropologists now carry out fieldwork in settings for which the ethnographic method was never designed, amongst powerful financial actors who are notoriously difficult to access, and in contexts which transcend geographical boundaries. This has engendered a re‐orientation of anthropology, to consider not only the economic lives of people but

Theorising the Impacts of Polycrisis on Employment Relations: Complexity and Diversity at a Global Scale

British Journal of Industrial Relations, EarlyView.
ABSTRACT Polycrisis—understood as intersecting crises that amplify each other rather than unfolding separately—poses profound challenges for employment relations theory and practice. The employment relationship is simultaneously a site where the effects of crises are most acutely experienced and a central mechanism through which profit is generated ...

Influence of Surface Complexity and Atmospheric Stability on Wind Shear and Turbulence in a Peri-Urban Wind Energy Site

Energies
The large-scale deployment of wind energy underscores the critical need for accurate resource characterization to reduce uncertainty in power estimates and to enable the installation of wind farms in increasingly complex terrains.

An Experimental Investigation of Streamwise and Vertical Wind Fields on a Typical Three-Dimensional Hill

Applied Sciences, 2020
To study the streamwise and vertical wind fields on a typical three-dimensional hill, wind tunnel tests were performed. The mean values and turbulence intensities of the streamwise and vertical wind speeds of the typical positions above the hill were ...

Dynamic Wave Trains: A Procedural Approach to Spatially Varying Ocean Synthesis

Computer Graphics Forum, EarlyView.
In this paper, we present a high performance procedural model capable of synthesizing and rendering a virtually infinite ocean. Our method exhibits spatial variations as the orientations, speed and choppiness of the waves is parametrized for each frequencies and each point in space. The provided visual abstract exhibits a sunset rendering of a large 40
