Two Modes of Self‐Organizing Development of Extreme Rainfall‐Producing Storms in South China

Abstract The convective‐scale dynamics of extreme rainstorms on monsoon coasts (South China) remain poorly understood. This study uses the advanced coupled model WRF‐Chem‐MOSAIC for a 90‐hr, 3‐km simulation, reasonably capturing the thermodynamic conditions, inhomogeneous near‐su...

Fast All‐Sky Hyperspectral Infrared Radiative Transfer With Physically Recursive Cloud Treatment

Abstract Clouds strongly modify thermal infrared radiances through absorption, emission, and multiple scattering, yet rigorous line‐by‐line (LBL) gas absorption coupled with multi‐stream scattering remains too expensive for large ensembles of all‐sky hyperspectral simulations. We...

Policy and temperature associations with gas-specific G7 transport emissions: Temporal predictability and geographic transportability

This repository contains the processed datasets, metadata, analysis code, and replication materials for the study “Policy and temperature associations with gas-specific G7 transport emissions: Temporal predictability and geographic transportability.” The study examines annual tra...

Tortoise-Inspired Magnetically Actuated Soft Robot Enabled by Segmented Legs with Programmable Bending

Inspired by the natural curvature and jointed configuration of tortoise limbs, this paper presents a magnetically controlled soft robot based on a “programmable intrinsic curvature” design paradigm. When corrugated flexural notches are introduced into a single-material elastomeri...

Moves for Bergman Algebras

We define Bergman presentations and Bergman algebras associated to Bergman presentations. These algebras embrace various generalisations of Leavitt path algebras. A Bergman presentation can be visualised by a Bergman graph, which is a finite bicoloured hypergraph satisfying two c...

AMOC Weakening Controls δ 18 O but Not Rainfall in North China During Deglacial Abrupt Events

Abstract East Asian Summer Monsoon (EASM) varied at orbital and millennial timescales during the Last Deglaciation (∼20–11 ka). The uniform δ 18 O response in East China is often linked to EASM circulation that drives a precipitation dipole in North and South China on orbital sca...

Improving Radar Rainfall Estimate with Kalman Filter Based Bias Adjustment Methods

Abstract This study evaluates three real-time Kalman filter (KF) approaches—Mean Field (MKF), Site-Specific (SKF), and a novel Lagrangian (LKF)—to correct radar rainfall estimation biases. While the SKF addresses spatial heterogeneity by applying independent filters per gauge, th...

Short-Term Ground Gust Prediction Based on Fusion of Ground and High-Altitude Meteorological Data and Differential Polynomial Modeling

Accurate Short-term forecasting of gusts at 10 m above ground level is challenging because gridded meteorological variables exhibit persistence, nonstationarity, and abrupt transitions. This study proposes a Temporal Adaptive Difference Polynomial Network (TADPN) using 8760 hourl...

A Physics‐Guided Feature Selection Machine Learning Approach for Cloud Probability Retrieval and Detection From TEMPO Imagery

Abstract Accurate cloud detection is critical for reliable retrievals of aerosols and trace gases from remote‐sensing measurements. TEMPO provides unprecedented hourly observations over North America, but radiometric calibration biases, thousands of spectral channels, and limited...

The Impact of Urbanization on Tropical Cyclone Rainfall Over Complex Coastal Terrain

Abstract Rapid coastal urbanization alters land–atmosphere interactions and can modify tropical cyclone (TC) rainfall. This study examines urbanization effects on TC rainfall in the Yongjiang River basin, China, using the Weather Research and Forecasting model. Two TCs (Lekima 20...

Predicting forecast errors with diffusion model for uncertainty quantification in wind speed nowcasting

Abstract. Weather forecasts are inherently uncertain due to the chaotic nature of the atmosphere and unavoidable errors. Ensemble forecasting is the established approach for quantifying the uncertainty. However, it is both computationally expensive and inherently prone to under-d...

All electrical sub-nanosecond field-free switching of perpendicular magnetization with high magnetic field immunity

Spin-orbit torque magnetic random-access memory is a promising next-generation non-volatile memory technology featuring low power consumption, rapid operation, and high endurance. Conventional spin-orbit torque-induced deterministic perpendicular magnetization switching, however,...

This paper presents a pressure-robustness discretization for optimal control problems governed by the Stokes-Darcy system. We revisit the divergence constraint and interface normal continuity within a mixed finite element framework. A reconstruction operator is incorporated into...

Spatiotemporal linkage and transmission of urban heat islands in the Yangtze River Delta urban agglomeration: the role of urban heat advection

Abstract. Urban heat islands (UHIs) substantially modify the urban thermal environment, yet the contribution of non-local processes such as urban heat advection (UHA) in dense urban agglomerations remains poorly quantified. Using five years of high-density automatic weather stati...

A Deep‐Learning‐Based Wind Gust Estimation Scheme in Complex Terrain

Abstract Accurate prediction of gusts is critical for risk mitigation, but the turbulent processes that generate gusts are unresolved in conventional numerical weather prediction models. Here we introduce a deep‐learning‐based wind gust estimation scheme (DL‐GUST) that uses archi...

This study systematically evaluates the performance of GPM_IMERG and GSMaP_Gauge hourly precipitation products in typhoon rainfall over Mainland China. Using hourly gauge observations from the China Meteorological Administration (CMA)’s national basic meteorological stations as r...

Changes of Precipitation Extremes and Persistence Over the Tibetan Plateau Projected by a Convection‐Permitting Model

Abstract Extreme precipitation has increased over many regions in recent decades, but the simulation and projection remain particularly challenging over complex terrains, such as the Tibetan Plateau (TP). Here, we investigate the future changes in precipitation extremes and persi...

A diffusion-based multi-style image generation framework with adaptive weighted style fusion

Diffusion-based multi-style image generation aims to preserve the semantic structure of a content image while integrating visual characteristics from multiple style references. Existing style transfer and diffusion-based methods often rely on single-style guidance, fixed prompts,...
