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...
Overheat Instability in an Ascending Moist Air Flow as a Mechanism of Hurricane Formation
Air Flow Mechanism Hurricane Formation
2011/9/6
The universal instability mechanism in an ascending moist air flow is theoretically proposed and analyzed. Its origin comes to the conflict between two processes: the increasing of pressure forcing ap...
Heterogeneous reactions of carbonyl sulfide on mineral oxides: mechanism and kinetics study
carbonyl sulfide mineral oxides mechanism and kinetics study
2010/11/29
The heterogeneous reactions of carbonyl sulfide (OCS) on the typical mineral oxides in the mineral dust particles were investigated using a Knudsen cell flow reactor and a diffuse reflectance UV-vis s...
Nanoparticles in boreal forest and coastal environment: a comparison of observations and implications of the nucleation mechanism

Biomass burning in the Indochina Peninsula (Indochina) is one of the important ozone sources in the low troposphere over East Asia in springtime. Moderate Resolution Imaging Spectroradiometer (MODIS) ...
Mechanism reduction for the formation of secondary organic aerosol for integration into a 3-dimensional regional air quality model: α-pinene oxidation system
Mechanism reduction secondary organic aerosol α-pinene oxidation system
2009/7/15
A detailed α-pinene oxidation mechanism was reduced systematically through the successive application of five mechanism reduction techniques. The resulting reduced mechanism preserves the ozone- and o...
Mainz Isoprene Mechanism 2（MIM2）: an isoprene oxidation mechanism for regional and global atmospheric modelling
