Aerosol optical properties and radiative forcing in the high Himalaya based on measurements at the Nepal Climate Observatory-Pyramid site (5079 m a.s.l.)
the high Himalaya measurements the Nepal Climate Observatory-Pyramid site
2010/8/13
Intense anthropogenic emissions over the Indian sub-continent lead to the formation of layers of particulate pollution that can be transported to the high altitude regions of the Himalaya-Hindu-Kush (...
Cirrus clouds in a global climate model with a statistical cirrus cloud scheme
Cirrus clouds a global climate model a statistical cirrus cloud scheme
2010/8/13
A statistical cirrus cloud scheme that accounts for mesoscale temperature perturbations is implemented in a coupled aerosol and atmospheric circulation model to better represent both subgrid-scale sup...
Aerosol-induced changes of convective cloud anvils produce strong climate warming
convective cloud anvils strong climate warming
2010/8/13
The effect of aerosol on clouds poses one of the largest uncertainties in estimating the anthropogenic contribution to climate change. Small human-induced perturbations to cloud characteristics via ae...
The net climate impact of coal-fired power plant emissions
The net climate impact coal-fired power plant
2010/8/12
Coal-fired power plants influence climate via both the emission of long-lived carbon dioxide (CO2) and short-lived ozone and aerosol precursors. Using a climate model, we perform the first study of th...
Chaotic background of large-scale climate oscillations
Chaotic background large-scale climate oscillations
2010/4/6
It is shown that the periodic alteration of night and day provides a chaotic dissipation mechanism for the North Atlantic (NAO) and Southern (SOI) climate oscillations. The wavelet regression detrende...
Estimations of climate sensitivity based on top-of-atmosphere radiation imbalance
climate sensitivity top-of-atmosphere radiation imbalance
2010/2/21
Large climate feedback uncertainties limit the accuracy in predicting the response of the Earth's climate to the increase of CO2 concentration within the atmosphere. This study explores a potential to...

Quantitative assessment Southern Hemisphere ozone chemistry-climate model
2010/2/21
Stratospheric ozone recovery in the Southern Hemisphere is expected to drive pronounced trends in atmospheric temperature and circulation from the stratosphere to the troposphere in the 21st century; ...
Northern winter stratospheric temperature and ozone responses to ENSO inferred from an ensemble of Chemistry Climate Models
Northern winter stratospheric temperature ozone responses Chemistry Climate Models
2009/12/3
The connection between the El Niño Southern Oscillation (ENSO) and the Northern polar stratosphere has been established from observations and atmospheric modeling. Here a systematic inter-compa...
Comment on "Quantitative performance metrics for stratospheric-resolving chemistry-climate models" by Waugh and Eyring (2008)
Quantitative performance metrics stratospheric-resolving chemistry-climate models Waugh Eyring
2009/12/3
This comment focuses on the statistical limitations of a model grading, as applied by D. Waugh and V. Eyring (2008) (WE08). The grade g is calculated for a specific diagnostic, which basically relates...
Terrestrial climate variability and seasonality changes in the Mediterranean region between 15 000 and 4000 years BP deduced from marine pollen records

2009/11/3
Here we use a very simple conceptual model in an attempt to reduce essential parts of the complex nonlinearity of abrupt glacial climate changes (the so-called Dansgaard-Oeschger events) to a few simp...
Comparison of a global-climate model simulation to a cloud-system resolving model simulation for long-term thin stratocumulus clouds
