Regime dependent instability as a transition mechanism in large-scale atmospheric flow
regimes instability baroclinic
2015/9/30
Two apparently distinct approaches to studying the observed low frequency variability in the atmosphere have evolved over the past few years. One approach invokes multiple, recurrent flow regimes to e...
A diffusion-induced transition in the phase separation of binary fluid mixtures subjected to a temperature ramp
diffusion-induced transition binary fluid mixtures temperature ramp
2011/8/16
Abstract: Demixing of binary fluids subjected to slow temperature ramps shows repeated waves of nucleation which arise as a consequence of the competition between generation of supersaturation by the ...
Coarse, intermediate and high resolution numerical simulations of the transition of a tropical wave critical layer to a tropical storm
resolution numerical the transition of a tropical wave critical layer a tropical storm
2010/11/30
Recent work has hypothesized that tropical cyclones in the deep Atlantic and eastern Pacific basins develop from within the cyclonic Kelvin cat's eye of a tropical easterly wave critical layer located...
Post-coring entrapment of modern air in some shallow ice cores collected near the firn-ice transition: evidence from CFC-12 measurements in Antarctic firn air and ice cores
modern air shallow ice cores the firn-ice transition CFC-12 measurements Antarctic firn air and ice cores
2010/8/13
In this study, we report measurements of CFC-12 (CCl2F2) in firn air and in air extracted from shallow ice cores from three Antarctic sites. The firn air data are consistent with the known atmospheric...
Numerical simulations of contrail-to-cirrus transition – Part 2: Impact of initial ice crystal number, radiation, stratification, secondary nucleation and layer depth

2010/2/21
Simulations of contrail-to-cirrus transition over up to 6 h were performed using a LES-model. The sensitivity of microphysical, optical and geometric contrail properties to relative humidity RHi, temp...
Comment on “Aerosol radiative forcing and climate sensitivity deduced from the Last Glacial Maximum to Holocene transition”, by P. Chylek and U. Lohmann, Geophys. Res. Lett., 2008
Aerosol radiative climate sensitivity Last Glacial Maximum Holocene transition
2009/12/3
In a recent paper, Chylek and Lohmann (2008) used data from the Vostok ice core together with simple energy balance arguments to simultaneously estimate both the dust radiative forcing effect and the ...
