A novel wake model for wind farm design on complex terrains [PDF]

, 2018
A numerical wake model that is capable of simulating wind turbine wake effects over complex terrains is proposed in this work. Currently, full-scale computational fluid dynamics (CFD) simulations are required to simulate wake effects over complex ...

Post‐Fire Soil Organic Carbon Dynamics: Decline and Recovery Over Two Decades

Land Degradation &Development, EarlyView.
ABSTRACT Wildfire can significantly alter soil organic carbon (SOC) dynamics in forest ecosystems, with complex temporal patterns following fire events. However, research on post‐fire SOC recovery remains limited, particularly in dry‐warm valley regions that are prone to frequent forest fires.

Effects of Organic Fertilizer Substitutions on Latex Yield and Soil Fertility in Hevea brasiliensis Plantations: A Case Study in Southern Philippines

Land Degradation &Development, EarlyView.
ABSTRACT Rubber plantations can be a major source of income for small landholder farmers in rural communities across Southern Asia. However, rising fertilizer costs and progressive soil degradation threaten long‐term productivity and economic viability.

Research on Path Optimization for UAV-Vehicle Collaboration in Emergency Rescue

Journal of Advanced Transportation
With the rapid development of the low-altitude economy, unmanned aerial vehicles (UAVs) have exhibited enormous potential in emergency rescue and material delivery fields due to their flexibility; however, individual UAVs are often constrained by ...

Troubling terrains: tactics for traversing and transforming contemporary educational research

, 2008
Troubling Terrains engages with the idea of educational research as locations, as places, as sites, as spaces as terrains. It explores multiple ways in which these terrains may be contentious, contested and controversial and shows how such terrains may ...

Aerial Seeding for Forest and Landscape Restoration: A Systematic Review of Technology, Challenges, and Future Directions

Land Degradation &Development, EarlyView.
ABSTRACT Land degradation is a critical global challenge, threatening biodiversity, food security, and livelihoods. Ecological restoration has therefore become a priority, with aerial seeding emerging as a key method to address issues of scale, accessibility, and efficiency. By dispersing seeds from aircraft or drones, aerial seeding complements ground‐

Drivers of tropical rainforest biomass in Papua New Guinea: large trees and taxonomic diversity dominate over other drivers

Oikos, EarlyView.
Tropical forests are among the most diverse and productive ecosystems globally, with aboveground biomass (AGB) storing a substantial portion of terrestrial carbon. While biodiversity, composition, and forest structure have been shown to affect AGB, their relative roles, interactions, and direct and indirect effects, with consideration of tree‐size ...

Conservation gap analysis for wild grapevines (Vitis L.) of the Americas

PLANTS, PEOPLE, PLANET, EarlyView.
Wild grapevines (Vitis L.) native to the Americas are ecologically and culturally important plants that are also critical to the global cultivated grape industry as sources of traits for crop innovation, but many of these species are poorly documented and insufficiently conserved.

Nowcasting convective cores using deep learning

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Key findings: •$$ \bullet $$ Network for Nowcasting Convective Cores (NetNCC) has considerable potential for convective storm nowcasting and the development of early warning systems for extreme rainfall. •$$ \bullet $$ Skilful nowcasts of convective cores are obtained at fine spatial resolutions (<30km$$ <30\kern0.15em \mathrm{km} $$) for up to 2 hr ...

Enhancing severe convection forecasts with microwave radiance assimilation in limited‐area models

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Microwave satellite radiances remain largely underexploited in convection‐permitting limited‐area models. We assess the assimilation of humidity‐sensitive radiances from the MHS instrument in the operational ICON‐2I model, improving the precipitation forecast of a severe convective event over the Marche region, Italy, substantially by correcting ...
