Representation of nucleation mode microphysics in global aerosol microphysics models [PDF]

, 2013
Abstract. In models, nucleation mode (1 nm < Dp < 10 nm) particle microphysics can be represented explicitly with aerosol microphysical processes or can be parameterized to obtain the growth and survival of nuclei to the model's lower size boundary.

Against Modal Humeanism

Analytic Philosophy, EarlyView.
ABSTRACT Ted Sider defends mereological nihilism against the possibility of gunk. He argues that if we accept modal Humeanism, then the possibility of gunk poses no threat to nihilism. This paper argues that Sider's argument fails because nihilism remains vulnerable to the possibility of gunk, even under modal Humeanism.

Metaphysical dependence and the subset relation between powers

The Southern Journal of Philosophy, EarlyView.
Abstract What is the relation between the token powers of higher‐level occurrences and the token powers of more basic physical occurrences? In related but somewhat different ways, Sydney Shoemaker and Jessica Wilson argue that the former are a proper subset of the latter, and that this can provide a viable account of higher‐level causation within a ...

On WRF hybrid-dynamic regression approach in heavy rainfall forecasting over the Northern of Thailand

Frontiers in Environmental Science
Rainfall forecasting in Northern Thailand presents considerable challenges due to the complex topography of the region and its highly variable climatic conditions, particularly during periods of heavy rainfall in August. This is compounded by limitations

Observations of Electric Fields Sounding in the Mature Stage of a Thunderstorm

Geoscience Data Journal, Volume 13, Issue 3, July 2026.
Successive electric field soundings separated by only 6 min provided a rare view of charge structure of a mature thunderstorm. The observations reveal horizontally inhomogeneous charge regions, an unusually deep upper negative layer, and charge features that cannot be readily explained by current thunderstorm electrification mechanisms. ABSTRACT In the

Microphysical Characteristics of a Squall Line Modulated by the Northeast China Cold Vortex Using Polarimetric Radar and Disdrometer Observations

Remote Sensing
Heavy precipitation in Northeast China is frequently modulated by the Northeast China Cold Vortex (NCCV), although the microphysical processes within squall lines under such conditions remain insufficiently understood. This study presents a comprehensive

Anthropogenic Pollution Accounts for a Substantial Part of Cloud Condensation Nuclei in North African Dust Layer

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Cloud condensation nuclei (CCN) modulate the properties and thus the climate effects of clouds. The North African dust plume is an important source of CCN in the North Atlantic trade‐wind zone. Yet, research into the nature and sources of these CCN is sparse, making it difficult to fully assess related cloud effects. Using combined airborne in

Imminent Localized Precipitation Preceded by a Surge in Cloud‐Base Descent and Reflectivity

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract The nowcasting of localized precipitation (LP) is often limited by insufficient observation of the vertical cloud evolution preceding rainfall. Here we systematically tracked rapid cloud development within 2 hr before LP onset, utilizing cloud data collected in 2024 from the millimeter‐wavelength cloud radar network across China, together with

Aerosols Shape the Vertical Structure of Convective Overshooting in Southeast Asia Through Microphysical Processes

Geophysical Research Letters
Convective overshooting significantly influences atmospheric material and energy cycles and can cause severe social impacts; nevertheless, aerosol effects on its microphysical structure and associated extreme weather remain unclear. Using a more accurate

Assessing the Impact of Countergradient Fluxes on the General Circulation in the Community Atmosphere Model

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Parameterizing boundary layer turbulence in Earth System Models (ESMs) introduces a key source of uncertainty. Here, we explore the impact of implementing a prognostic formulation (PMF) for momentum flux, which permits countergradient (CG) fluxes.
