Shrunken Locally Linear Embedding for Passive Microwave Retrieval of Precipitation [PDF]

, 2014
This paper introduces a new Bayesian approach to the inverse problem of passive microwave rainfall retrieval. The proposed methodology relies on a regularization technique and makes use of two joint dictionaries of coincidental rainfall profiles and ...

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

Geophysical 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

Journal 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

Atmospheric 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

Meteorological 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.

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

New 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 ...

Deep Convection‐Driven Downward Transport of Trace Gases and Aerosols From the Free Troposphere to the Boundary Layer

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Deep convective clouds regulate Earth's energy and moisture budgets, yet their impact on the atmospheric boundary layer (BL) composition remains underexplored. Using long‐term observations from three mid‐latitude sites, we show that deep convection (DC) consistently enhances nighttime surface ozone and is often accompanied by modest increases ...

Trend of North African Dust Storms and Potential Link to Climate Change

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 3, 16 February 2026.
Abstract Over recent decades, North African dust storms have undergone marked variability, reflecting complex interactions between regional climate processes and environmental change. Using four decades (1984–2023) of visibility‐based observational records, we examine regional and seasonal trends in dust storm frequency across the Sahel and the Sahara,

Investigating the Microphysical Characteristics and Environmental Influences of Warm‐Rain Precipitation in Fuzhou Region of China

Earth and Space Science, Volume 13, Issue 2, February 2026.
Abstract Microphysical characteristics of warm‐rain precipitation that occurred in Fuzhou region during warm seasons of 2022 and 2023 have been investigated by using polarimetric radar data. Results of a modified warm‐rain identification algorithm indicate positive ZDR variation in the liquid layer should be added as a criterion to prevent events ...
