Classification of Biological Scatters Using Polarimetric Weather Radar

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Weather radar holds the capability to monitor the extensive migration of bird and insect species. In particular, polarimetric weather radar can enhance aerial ecological monitoring by quantifying target shape through the measurement of polarization ...

A New Hydroclimatic Signature: Negative NAO Dominance Under Weak La Niña Conditions During the 2025–2026 Northwest Africa Floods

open access: yesInternational Journal of Climatology, EarlyView.
Conceptual hydroclimatic pathway linking the concurrent negative North Atlantic Oscillation (NAO) phase and weak La Niña conditions to extreme February rainfall and flash flooding in Northwest Africa. ABSTRACT The winter of 2025–2026 in Morocco exhibited a rapid hydroclimatic transition from prolonged drought to widespread flooding, representing an ...

ERA5 Can Overstate Changes in the Frequency of Extreme Heat: A New Zealand Case Study

open access: yesInternational Journal of Climatology, EarlyView.
ERA5 reproduces broad patterns of summer warming across New Zealand but underestimates temperature variability and warm‐tail extremes, biasing estimates of extreme heat risk. ABSTRACT Summertime temperature extremes exert profound impacts on human health, ecosystems, and infrastructure, yet their characteristics and drivers remain poorly quantified in ...

Characteristics of Boundary Layer Height Variations in Global Arid Regions and Their Sensitivity to Influencing Energy Factors

open access: yesInternational Journal of Climatology, EarlyView.
Global warming has intensified drought impacts across most arid regions, altering surface energy partitioning and atmospheric boundary layer (ABL) development. Using 1979–2018 ERA‐Interim reanalysis data, we show that the long‐term mean boundary layer height (BLH) over global arid regions is approximately 841.8 m, nearly 200 m higher than over humid ...

Evaluation of Radar Observation Contribution to CMA-MESO Assimilation System

open access: yes应用气象学报
Radar wind observations, such as Doppler weather radar radial velocity and wind profiler data, are critical for initializing numerical weather prediction (NWP) models due to their high spatiotemporal resolution.

RECAP Analysis: A Novel Analytical Tool for Strategic Diagnosis in Dynamic Environments

open access: yesStrategic Change, EarlyView.
ABSTRACT Strategic diagnosis remains a persistent challenge for managers operating in dynamic environments. Existing frameworks—from SWOT to VRIO—have been criticized for being either analytically shallow or theoretically inaccessible as practical tools.

Revealing Dust Source Changes in East Asia From Past to Future: An Interpretable Deep Learning Approach

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Aeolian dust source areas are controlled by climate and human activities and are closely associated with land degradation, yet their long‐term evolution under global warming remains insufficiently quantified. An integrated framework that couples a U‐Net segmentation model with Shapley Additive Explanations (SHAP) was built to map and attribute

Dynamic Performance Enhancement of a High‐Agility Hypersonic Mechanical System via a Learning‐Augmented Robust Control Architecture

open access: yesInternational Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT The design of control systems for high‐agility mechanical systems operating in extreme environments is a significant challenge in nonlinear dynamics. This paper addresses the complex dynamic control problem of a hypersonic interceptor, modeled as a multi‐input multi‐output (MIMO) mechanical system characterized by strong aerodynamic cross ...
