Asian Hydroclimate Changes and Mechanisms in the Preboreal from an Annually-laminated Stalagmite, Daoguan Cave, Southern China
Daoguan Cave the Preboreal Bond Event ASM global changes
2018/4/10
One-year-resolved and annually-counted stalagmite multi-proxies (δ18O, δ13C, and layer width) from Daoguan Cave, Guizhou Province revealed detailed variability regarding the Asian Summer Monsoon (ASM)...
Analysis of a hyper-diverse seed dispersal network: modularity and underlying mechanisms
Birds body mass complex networks fish
2015/11/13
Mutualistic interactions involving pollination and ant-plant mutualistic networks typically feature tightly linked
species grouped in modules. However, such modularity is infrequent in seed dispersal...
Mechanisms of Reef Coral Resistance to Future Climate Change
Future Climate Change Coral Resistance
2015/12/11
Reef-building corals have experienced global declines resulting from
bleaching events sparked by pulses of warm water exposure (1–4). However, corals in naturally warm environments can have high res...
Formation of secondary aerosols over Europe: comparison of two gas-phase chemical mechanisms
secondary aerosols Europe two gas-phase chemical mechanisms
2011/2/24
The impact of two recent gas-phase chemical kinetic mechanisms (CB05 and RACM2) on the formation of secondary inorganic and organic aerosols is compared for simulations of PM2.5 over Europe between 15...
Eta-CMAQ air quality forecasts for O3 and related species using three different photochemical mechanisms (CB4, CB05, SAPRC-99): comparisons with measurements during the 2004 ICARTT study
Eta-CMAQ air quality forecasts three different photochemical mechanisms the 2004 ICARTT study
2010/8/12
A critical module of air quality models is the photochemical mechanism. In this study, the impact of the three photochemical mechanisms (CB4, CB05, SAPRC-99) on the Eta-Community Multiscale Air Qualit...
Kinetics and mechanisms of heterogeneous reaction of NO2 on CaCO3 surfaces under dry and wet conditions
heterogeneous reaction CaCO3 surfaces dry wet
2010/2/1
With increasing NO2 concentration in the troposphere, the importance of NO2 reaction with mineral dust in the atmosphere needs to be evaluated. Until now, little is known about the reaction of NO2 wit...
Mechanisms and time scales of glacial inception simulated with an Earth system model of intermediate complexity
Mechanisms Milankovitch forcing time scales
2009/12/3
We investigate glacial inception and glacial thresholds in the climate-cryosphere system utilising the Earth system model of intermediate complexity CLIMBER-2, which includes modules for atmosphere, t...
Kinetic modeling of nucleation experiments involving SO2 and OH: new insights into the underlying nucleation mechanisms
Kinetic modeling nucleation experiments SO2 OH underlying nucleation mechanisms
2009/11/9
Nucleation is an important source of atmospheric aerosols which have significant climatic and health implications. Despite intensive theoretical and field studies over the past decades, the dominant n...
Simulating mixed-phase Arctic stratus clouds: sensitivity to ice initiation mechanisms
mixed-phase Arctic stratus clouds ice initiation mechanisms sensitivity
2009/7/23
The importance of Arctic mixed-phase clouds on radiation and the Arctic climate is well known. However, the development of mixed-phase cloud parameterization for use in large scale models is limited b...
Modelling of cirrus clouds – Part 2: Competition of different nucleation mechanisms
Modelling of cirrus clouds different nucleation mechanisms
2009/5/7
We study the competition of two different freezing mechanisms (homogeneous and heterogeneous freezing) in the same environment for cold cirrus clouds. To this goal we use the recently developed and va...
Transport mechanisms for synoptic, seasonal and interannual SF6 variations and“age”of air in troposphere
