Sentences with phrase «include microphysics»

«Some other models like CESM1 did include microphysics and an indirect aerosol effect, and had slightly lower 20th Century warming than observed... yet its climate sensitivity is higher than for [some other models that don't include the indirect aerosol effect]... the [GWPF] comment presumes that models have been tuned to reproduce the 20th Century temperature record, but this is mostly not true»

On the matter of the role of condensation nuclei, a few general circulation models do have some crude representation of nucleation microphysics in their convection or cloud schemes, but it certainly isn't the key factor in the weak increase of precipitation with temperature, which is seen in all GCM's including those with very basic representations of convection.

For the disciplinary matrix of climate science, no one source is sufficient, but it should include some of the books I have commented on before: «Modern Thermodynamics» by Kondepudi and Prigogine; «Thermal Physics of the Atmosphere» by Ambaum; «Thermodynamics, Kinetics, and Microphysics of Clouds» by Khvorostyanov and Curry (that is a thick, dense, tough slog, let me warn you!)

The meeting will mainly cover the following themes, but can include other topics related to understanding and modelling the atmosphere: ● Surface drag and momentum transport: orographic drag, convective momentum transport ● Processes relevant for polar prediction: stable boundary layers, mixed - phase clouds ● Shallow and deep convection: stochasticity, scale - awareness, organization, grey zone issues ● Clouds and circulation feedbacks: boundary - layer clouds, CFMIP, cirrus ● Microphysics and aerosol - cloud interactions: microphysical observations, parameterization, process studies on aerosol - cloud interactions ● Radiation: circulation coupling; interaction between radiation and clouds ● Land - atmosphere interactions: Role of land processes (snow, soil moisture, soil temperature, and vegetation) in sub-seasonal to seasonal (S2S) prediction ● Physics - dynamics coupling: numerical methods, scale - separation and grey - zone, thermodynamic consistency ● Next generation model development: the challenge of exascale, dynamical core developments, regional refinement, super-parametrization ● High Impact and Extreme Weather: role of convective scale models; ensembles; relevant challenges for model development

And noting «zonal mean - winds constitute an important element of global atmospheric circulation,» they go on to suggest,» if the solar cycle can influence zonal mean - winds, then it may affect other features of global climate as well, including oscillations such as the NAO and MJO, of which zonal winds are an ingredient» Thus, «the cause of this forcing» as they describe it, «likely involves some combination of solar wind, galactic cosmic rays, ionosphere - Earth currents and cloud microphysics.»

Furthermore, a model that could realistically simulate the impact of increasing atmospheric particle concentration on climate must eventually include the simultaneous coupled effects of all the important atmospheric processes, such as fluid motions and cloud microphysics, in addition to the radiative transfer effects.»

Over the past 10 years, however, an alternative school of thought has emerged: that detailed microphysics need not be included in models in order to accurately simulate tropical tropospheric humidity.
