Excellent Microwave Absorption of Polyurethane Nanocomposites Engineered With Graphene Nanoplatelets and Magnetite

Journal of Polymer Science, EarlyView.
Reflection loss behavior and microwave absorption mechanism of graphene nanoplatelet and magnetite reinforced polyurethane nanocomposites, highlighting synergistic dielectric and magnetic losses. ABSTRACT The escalating growth in telecommunication technology has led to a surge in electromagnetic pollution due to the increase in electronic devices. This

Spatial Variability of Permafrost and Active Layer Thickness in a Forested Hillslope of the Taiga Shield

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT Under continued climate warming, understanding present‐day permafrost distribution and the controls on ground thaw are critical for predicting permafrost thaw trajectories and associated implications. This study presents a high‐resolution investigation of permafrost extent and active layer thickness (ALT) across a coniferous forested hillslope

Consecutive-frame latent space normal estimation under sparse point clouds for 4D millimeter-wave radar

Journal of Measurement Science and Instrumentation
Aiming at the sparsity of point cloud data and the low accuracy of spatial alignment exhibited by millimeter-wave frequency-modulated continuous-wave (FMCW) radar in outdoor motion scenarios, a lightweight model for spatial alignment was proposed.

Medicane characteristics from high‐resolution satellite radar observations

Quarterly Journal of the Royal Meteorological Society, EarlyView.
This study uses high‐resolution observations from satellite synthetic aperture radar (SAR) to reveal that medicanes, cyclones with tropical features in the Mediterranean basin, have dynamical characteristics with attributes comparable with those of tropical cyclones of similar intensities, but smaller outer sizes and Rossby numbers.

Moisture and wind effects of Rossby waves on Western Pacific Intertropical Convergence Zone breakdown events

Quarterly Journal of the Royal Meteorological Society, EarlyView.
(a) Organized convection: clouds are clustered at the southern edge of the domain, aligning with the warmest SST. Northeasterly winds prevail, facilitating convection confinement to the southern part of the domain. (b) ITCZ breakdown: the clouds are spread throughout the domain.

Assessing high‐resolution numerical models and bottom‐boundary factors for a Mediterranean heavy precipitation event

Quarterly Journal of the Royal Meteorological Society, EarlyView.
State‐of‐the‐art, convection‐permitting NWP models reproduced the main features of the October 22–23, 2019 heavy precipitation event in Catalonia. However, slight configuration changes yielded varying streamflow responses and statistical performance, highlighting the challenge of simulating these events in Mediterranean medium‐sized basins ...
