A comprehensive numerical study of aerosol-cloud-precipitation interactions in marine stratocumulus [PDF]

open access: yes, 2011
Three-dimensional large-eddy simulations (LES) with detailed bin-resolved microphysics are performed to explore the diurnal variation of marine stratocumulus (MSc) clouds under clean and polluted conditions.

Environmental Effects of Volcanic Volatile Fluxes From Subaerial Large Igneous Provinces

open access: yesGeophysical Monograph Series, Page 103-116., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

The impact of the 1783-1784 AD Laki eruption on global aerosol formation processes and cloud condensation nuclei [PDF]

open access: yes, 2010
The 1783–1784 AD Laki flood lava eruption commenced on 8 June 1783 and released 122 Tg of sulphur dioxide gas over the course of 8 months into the upper troposphere and lower stratosphere above Iceland. Previous studies have examined the impact of the

An assessment of aerosol‐cloud interactions in marine stratus clouds based on surface remote sensing [PDF]

open access: yes, 2009
An assessment of aerosol-cloud interactions (ACI) from ground-based remote sensing under coastal stratiform clouds is presented. The assessment utilizes a long-term, high temporal resolution data set from the Atmospheric Radiation Measurement (ARM ...

A review of the theoretical basis for bulk mass flux convective parameterization [PDF]

open access: yes, 2009
Most parameterizations for precipitating convection in use today are bulk schemes, in which an ensemble of cumulus elements with different properties is modelled as a single, representative entraining-detraining plume.

The impact of the mesh size and microphysics scheme on the representation of mid-level clouds in the ICON model in hilly and complex terrain [PDF]

open access: yesAtmospheric Chemistry and Physics
The rise in computational power in recent years has enabled research and national weather services to conduct high-resolution simulations down to the kilometric (Δx=𝒪(1 km)) and even to hectometric (Δx=𝒪(100 m)) scales for both weather and climate ...

CIP-CSLR Scheme for Condensation and Evaporation Calculations of Water Droplets [PDF]

open access: yes, 2010
We present a number-density advection based method designed to calculate the condensation and evaporation of water droplets. An Eulerian-in-radius discretization scheme is adopted, making the present model suitable for use in the spectral bin model for ...
