Evaluating the Performance of a Convection-Permitting Model by Using Dual-Polarimetric Radar Parameters: Case Study of SoWMEX IOP8

open access: yesRemote Sensing, 2020
In this study, a dual-polarimetric radar observation operator is established and modified for the Taiwan area for the purpose of model verification. A severe squall line case during the Southwest Monsoon Experiment Intensive Observing Period 8 (SoWMEX ...

Hemispheric Synoptic Patterns Control Rainfall and Long‐Range Aerosol Transport in the Amazon

open access: yesGeophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract The transatlantic transport of dust and smoke aerosols from Africa to South America is a large‐scale, year‐round process that affects atmospheric and nutrient cycling in the Amazon rainforest. We analyze daily variations in black carbon at the Amazon Tall Tower Observatory (ATTO) to investigate how Atlantic synoptic‐scale meteorology ...

A Climatology of Mesoscale Convective System Hazards in the United States and Their Representation in a Convection‐Permitting Model

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 5, 16 March 2026.
Abstract Mesoscale convective systems (MCSs) are large, organized convective storms that frequently produce flash floods and other severe hazards such as damaging winds, hail, and tornadoes. Developing an observationally based MCS hazard climatology is important for establishing a baseline to evaluate the representation of these events in numerical ...

The Predictability of the Southern England 23 October 2022 Severe Downbursts

open access: yesAtmospheric Science Letters, Volume 27, Issue 3, March 2026.
Accurate prediction of damaging straight‐line wind events from convection helps keep people safe. Using four regional ensemble prediction systems, we determine the predictability of the different aspects of the microburst wind potential index (left), which can be used to estimate the spread in expected downburst speed (right).

Fine‐Tuning Lightning Nowcasting for a New Domain

open access: yesMeteorological Applications, Volume 33, Issue 2, March/April 2026.
The study applied transfer learning to fine‐tune LightningCast, an artificial neural network originally developed for lightning prediction over the U.S., for use in Brazil. Results demonstrate that transfer learning effectively adapts lightning nowcasting models to new regions, enhancing performance and reducing computational cost.

Investigation of mesoscale meteorological phenomena as observed by geostationary satellite [PDF]

open access: yes, 1982
Satellite imagery plus conventional synoptic observations were used to examine three mesoscale systems recently observed by the GOES-EAST satellite. The three systems are an arc cloud complex (ACC), mountain lee wave clouds and cloud streets parallel to ...

Nest Counts of Kororā/Little Penguins on Horomaka/Banks Peninsula, New Zealand

open access: yesNew Zealand Journal of Zoology, Volume 53, Issue 1, March 2026.
To better understand the population trends of kororā/little penguins (Eudyptula minor), the Horomaka/Banks Peninsula Kororā Survey of nesting colonies was conducted across two consecutive breeding seasons (November–January 2020/2021 and 2021/2022). Due to the number of sites and time requirements, volunteers were recruited to search 89 breeding sites ...
