Characterization of synoptic environment for mesoscale convective systems over South Korea using ERA5 reanalysis data

Quarterly Journal of the Royal Meteorological Society, EarlyView.
In this study, the synoptic conditions for modes of mesoscale convective systems (MCSs) in South Korea are generalized based on composite analysis. The preferred precipitation region, synoptic patterns, moisture transport, sea surface temperature and thermodynamic and dynamic instabilities are characterized according to four modes: convective cells (CC)

Identifying precursor of Sumatra squall line

E3S Web of Conferences, 2023
Sumatra Squall Line (SSL) is a detectable mesoscale meteorological phenomenon at least prior to 3 hour using Doppler radar imagery interpretation. By identifying precursors, SSL can be detected 6-12 hours earlier before the occurences. Infrared data from MTSAT satellite were used to identify clusters of SSL clouds which then produce two types of SSL ...

Megaphone: Latency-conscious state migration for distributed streaming dataflows

, 2019
We design and implement Megaphone, a data migration mechanism for stateful distributed dataflow engines with latency objectives. When compared to existing migration mechanisms, Megaphone has the following differentiating characteristics: (i) migrations ...

Unmothered at Work: Organizational Silence Around Reproductive Loss

Gender, Work &Organization, EarlyView.
ABSTRACT An identity transition refers to changes in self‐concept that can result from professional or personal shifts. Although organizations increasingly support institutionally legible and culturally normative nonwork transitions, others remain professionally stigmatized or culturally unspeakable.

Analysis on a Squall Line and its Downburst over the Lower Reaches of Jinsha River

Gaoyuan qixiang
Squall lines often produce extremely disastrous gales and play a crucial role in the safety of hytropower stations.This article explores a squall line event over the lower reaches of Jinsha River on June 4， 2016， which brought 13-level wind at the canyon

Wet scavenging of soluble gases in DC3 deep convective storms using WRF-Chem simulations and aircraft observations [PDF]

, 2016
We examine wet scavenging of soluble trace gases in storms observed during the Deep Convective Clouds and Chemistry (DC3) field campaign. We conduct high-resolution simulations with the Weather Research and Forecasting model with Chemistry (WRF-Chem) of ...

Applicability Study of a Diffusion Transformer Forecasting Model in the Complex Terrain of Guizhou

Meteorological Applications, Volume 33, Issue 3, May/June 2026.
Performance comparison of the HARE model and the Fenglei baseline across four evaluation metrics (CSI, POD, FAR, and Frequency Bias) over a 142‐day verification period. ABSTRACT Precipitation nowcasting in complex terrains like the Guizhou Plateau is challenged by the blurry forecasts and premature dissipation common in traditional and early deep ...

Analysis of Dual-Polarimetric Radar Variables and Quantitative Precipitation Estimators for Landfall Typhoons and Squall Lines Based on Disdrometer Data in Southern China

Atmosphere, 2019
Typhoon rainstorms often cause disasters in southern China. Quantitative precipitation estimation (QPE) with the use of polarimetric radar can improve the accuracy of precipitation estimation and enhance typhoon defense ability.

Spatial Patterns of Shallow Clouds: Challenging the Concept of Defined Regimes

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Tropical shallow clouds are a major source of uncertainty in Earth's climate sensitivity, especially through their spatial arrangement, which global climate models do not represent. Efforts to understand their organization have partly relied on classifying observed scenes, identifying four patterns as archetypal regimes.

Urban Impacts on Convective Squall Lines over Chicago in the Warm Season—Part II: A Numerical Study of Urban Infrastructure Effects on the Evolution of City-Scale Convection

Atmosphere
Numerical models were employed to simulate the effects of urban infrastructure on the city-scale precipitation distribution during multiple closely occurring convective squall line events over Chicago. Two high-resolution simulations were inter-compared,
