IUTAM Symposium on Storm surge modelling and forecasting
Storm surge modelling forecasting
2016/7/19
Storm surges are the major geophysical threat to life and properties in coastal regions, being more widespread and frequent than tsunamis. Yet recent storm surge events around the globe raised painful...
CHIMERE 2013: a model for regional atmospheric composition modelling
regional atmospheric composition modelling CHIMERE 2013
2014/12/12
Tropospheric trace gas and aerosol pollutants have
adverse effects on health, environment and climate. In order
to quantify and mitigate such effects, a wide range of processes leading to the format...
Modelling deep convection and its impacts on the tropical tropopause layer
deep convection the tropical tropopause layer
2010/11/30
The UK Met Office's Unified Model is used at a climate resolution (N216, ~0.83°×~0.56°, ~60 km) to assess the impact of deep tropical convection on the structure of the tropical tropopause layer (TTL)...
A refinement of the emission data for Kola Peninsula based on inverse dispersion modelling
the emission data Kola Peninsula inverse dispersion modelling
2010/11/30
The study reviews the emission estimates of sulphur oxides (SOx) and primary particulate matter (PM) from the major industrial sources of Kola Peninsula. Analysis of the disagreements between the exis...
Isoprene emissions modelling for West Africa: MEGAN model evaluation and sensitivity analysis
Isoprene emissions modelling West Africa MEGAN model
2010/9/21
Isoprene emissions are the largest source of reactive carbon to the atmosphere, with the tropics being a major source region. These natural emissions are expected to change with changing climate and h...
Stratospheric water vapour budget and convection overshooting the tropopause: modelling study from SCOUT-AMMA
Stratospheric water vapour the tropopause SCOUT-AMMA
2010/9/14
The aim of this paper is to study the impacts of overshooting convection at a local scale on the water distribution in the tropical UTLS. Overshooting convection is assumed to be one of the processes ...
Volume nucleation rates for homogeneous freezing in supercooled water microdroplets: results from a combined experimental and modelling approach
Volume nucleation rates supercooled water microdroplets a combined experimental and modelling approach
2010/9/1
Temperature-dependent volume nucleation rate coefficients for supercooled water droplets, JV(T), are derived from infrared extinction measurements in a cryogenic laminar aerosol flow tube using a micr...

microphysical and meteorological controls precipitation cloud cellular structures Southeast Pacific stratocumulus
2010/8/16
Microphysical and meteorological controls on the formation of open and closed cellular structures in the Southeast Pacific are explored using model simulations based on aircraft observations during th...
Effects of resolution on the relative importance of numerical and physical horizontal diffusion in atmospheric composition modelling
numerical and physical horizontal diffusion atmospheric composition modelling
2010/8/12
Numerical diffusion induced by advection has a large influence on concentration of substances in atmospheric composition models. At coarse resolution numerical effects dominate, whereas at increasing ...
Sources of uncertainties in modelling black carbon at the global scale
black carbon the global scale
2010/8/12
Our understanding of the global black carbon (BC) cycle is essentially qualitative due to uncertainties in our knowledge of its properties. This work investigates two source of uncertainties in modell...
Widening the gap between measurement and modelling of secondary organic aerosol properties?

2010/3/16
The link between measured sub-saturated hygroscopicity and cloud activation potential of secondary organic aerosol particles produced by the chamber photo-oxidation of α-pinene in the presence or abse...
High-accuracy measurements of snow Bidirectional Reflectance Distribution Function at visible and NIR wavelengths——comparison with modelling results
High-accuracy measurements snow Bidirectional Reflectance Distribution Function NIR wavelengths
2010/3/16
High-accuracy measurements of snow Bidirectional Reflectance Distribution Function (BRDF) were performed for four natural snow samples with a spectrogonio-radiometer in the 500–2600 nm wavelength rang...
Modelling the optical and radiative properties of freshly emitted light absorbing carbon within an atmospheric chemical transport model
freshly emitted light carbon atmospheric chemical transport model
2010/2/21
Light absorbing carbon (LAC) aerosols have a complex, fractal-like aggregate structure. Their optical and radiative properties are notoriously difficult to model, and approximate methods may introduce...
