Drying Effect of Landfalling Tropical Cyclones

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract The high precipitation efficiency of tropical cyclones (TCs) is theorized to dehydrate the atmosphere, a process with important climate implications that has yet to be confirmed by direct observational evidence. Using satellite and reanalysis data, this study statistically examines the drying effect of landfalling TCs. Results indicate a local

Dynamic Versus Diabatic Controls on Atmospheric Variability in a Tropical Aquachannel

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 12, 28 June 2026.
Abstract Synoptic‐ to planetary‐scale atmospheric variability in the tropics is a potential source of predictability worldwide. However, current weather prediction models struggle to fully capture this variability. Here, we conduct tropical aquachannel simulations using the ICOsahedral Nonhydrostatic model with horizontal grid spacings of 13 and 5 km ...

Deployment Strategy Shapes the Polar Climate Response to Marine Cloud Brightening

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 12, 28 June 2026.
Abstract Marine cloud brightening (MCB) is a proposed solar climate intervention strategy that increases marine cloud reflectivity to cool Earth's surface. While previous studies have largely examined its global temperature and precipitation effects, little is known about how MCB deployment strategies influence polar climate and sea ice.

Substantial Diel Changes of Cloud Adjustments to Aerosols in Ship‐Tracks

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Clouds adjust their albedo, amount and liquid water path to anthropogenic aerosols, and produce a climate forcing. Such cloud adjustments are complex functions of both environmental conditions and interaction time. However, direct observations of temporal changes in cloud adjustments are limited. Here, we develop a method to show observational

Cloud response to lateral interactions from convective strength-variable neighbors

Geoscience Letters
The organization of convective clouds plays a key role in convective system development, yet the interactions between neighboring cloud entities remain unclear.

Differences in Lightning—Storm Microphysical Relationships in Subtropical South America Versus the Continental U.S. and Their Impact on Model Lightning Parameterizations

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Satellite studies have shown that some of the deepest convection with high lightning flash rates occurs downstream of the Andes in subtropical South America (SSA). Using high resolution ground‐based observations in SSA, we explore the relationship between lightning and radar‐inferred storm microphysics.

An Assessment of Representing Land‐Ocean Heterogeneity via CAPE Relaxation Timescale in the Community Atmospheric Model 6 (CAM6)

Journal of Advances in Modeling Earth Systems
The time needed by deep convection to bring the atmosphere back to equilibrium is called convective adjustment timescale or simply adjustment timescale, typically denoted by τ. In the Community Atmospheric Model|Community Atmosphere Model (CAM), τ is the

Mercury's Alfvén Wing Current System Under Sub‐Alfvénic Solar Wind Conditions: Insights From Global MHD Simulations

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Mercury's proximity to the Sun results in the lowest average Alfvénic Mach number in the upstream solar wind compared to any other planet. Under extreme conditions, the upstream Alfvén speed can exceed the solar wind speed, resulting in a sub‐Alfvénic interaction in which standing Alfvén wings form.

Stochastic parameterization: uncertainties from convection [PDF]

, 2011
In 2005, the ECMWF held a workshop on stochastic parameterisation, at which the convection was seen as being\ud a key issue. That much is clear from the working group reports and particularly the statement from working group\ud 1 that “it is clear that a stochastic convection scheme is desirable”. The present note aims to consider our current\ud status

Long‐Lived Anticyclonic Eddies Facilitate Convection in the Greenland Sea Over Multiple Consecutive Winters

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Wintertime open‐ocean convection is a key process in renewing deep water; however, the processes that promote convection on local scale remain poorly understood. We investigate the role of long‐lived anticyclonic eddies in facilitating deep convection in the Greenland Sea using a new model simulation and observations.
