Mesoscale Cellular Convection Detection and Classification Using Convolutional Neural Networks: Insights From Long‐Term Observations at ARM Eastern North Atlantic Site

Journal of Geophysical Research: Machine Learning and Computation, Volume 2, Issue 1, March 2025.
Abstract Marine boundary layer clouds are crucial in Earth's climate system. They frequently manifest as closed or open cell mesoscale cellular convection (MCC). MCC clouds are challenging to represent accurately in current climate models, highlighting the need for detailed observational data sets and in‐depth analyses. This study utilizes over 8 years

Attribution of 2022 August Heavy Precipitation Event in South Korea Using High‐Resolution Pseudo Global Warming Simulations: Sensitivity to Vertical Temperature Changes

Geophysical Research Letters, Volume 52, Issue 2, 28 January 2025.
Abstract This study examines the anthropogenic influences on the heavy precipitation event that occurred in early August 2022, South Korea, using a pseudo global warming (PGW) method with a convection‐permitting model. Pseudo global warming experiments for counterfactual natural non‐warming conditions (NAT) were conducted by removing anthropogenic ...

On the Use of InSAR for Estimating Timing Errors in Harmonie‐Arome Water Vapor Fields

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 1, 16 January 2025.
Abstract Due to its sensitivity to water vapor, high resolution, and global availability, interferometric satellite radar (InSAR) has a large but unexploited potential for the improvement of regional NWP models. A relatively straightforward approach is to exploit the exact instantaneous character of the InSAR data in data assimilation to improve the ...

Observation and Numerical Simulation of a Microburst Encounter by an Arriving Aircraft at Hong Kong International Airport During Intense Convective Weather on August 14, 2025

Advances in Meteorology, Volume 2025, Issue 1, 2025.
A microburst encounter near the ground was documented for the first time at Hong Kong International Airport (HKIA). Analysis of the flight data for the concerned aircraft revealed that it passed through at least three small vortices within the band of heavy rain. Most notably, the aircraft experienced an updraft–downdraft vertical velocity couplet when

The Triggering Mechanisms of a Short‐Duration Local Heavy Rainstorm Event in the Tarim Basin, China

Advances in Meteorology, Volume 2025, Issue 1, 2025.
The Tarim basin located in the western northwest China is the largest inland basin in the world and the core component of the arid region of the Central Asia. In recent years, the frequency of heavy rain and extreme precipitation events in the Tarim basin has increased substantially.

An Analytical Formula for Potential Water Vapor in an Atmosphere of Constant Lapse Rate

Terrestrial, Atmospheric and Oceanic Sciences, 2012
Accurate calculation of precipitable water vapor (PWV) in the atmosphere has always been a matter of importance for meteorologists. Potential water vapor (POWV) or maximum precipitable water vapor can be an appropriate base for estimation of probable ...

ANIR : Atacama Near-Infrared Camera for the 1.0-m miniTAO Telescope

, 2015
We have developed a near-infrared camera called ANIR (Atacama Near-InfraRed camera) for the University of Tokyo Atacama Observatory 1.0m telescope (miniTAO) installed at the summit of Cerro Chajnantor (5640 m above sea level) in northern Chile.

Effect of phase centre variation on tropospheric delay in PPP‐AR with low‐cost global navigation satellite systems receiver and antenna

IET Radar, Sonar &Navigation, Volume 18, Issue 12, Page 2737-2748, December 2024.
When PCV corrections are not applied, it is clear that ambiguity resolution fails to improve the accuracy of ZWD estimates. The SEPMX5 receiver consistently outperforms the UBLX9F receiver in scenarios where PCV corrections are applied. Abstract As low‐cost global navigation satellite systems receiver and antenna become increasingly prevalent for water
