Atmospheric scientists study fires to resolve ice question in climate models（图）
Atmospheric scientists fires resolve ice question climate models
2020/9/4
When fossil fuel or biomass burns, soot -- also known as black carbon -- fills the air. Black carbon is an important short-term climate driver because it absorbs solar energy and can affect the format...
Technique could help climate models sweat the small stuff
Technique climate models sweat the small stuff
2016/6/12
A team of physicists and mathematicians has come up with a statistical technique that puts the fine details back into computer simulations of large-scale phenomena like air circulation in the atmosphe...
Failure analysis of parameter-induced simulation crashes in climate models
parameter-induced simulation crashes climate models
2014/12/12
Simulations using IPCC (Intergovernmental Panel
on Climate Change)-class climate models are subject to fail
or crash for a variety of reasons.
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...
Exploiting the weekly cycle as observed over Europe to analyse aerosol indirect effects in two climate models
Europe aerosol indirect effects climate models
2009/11/19
A weekly cycle in aerosol pollution and some meteorological quantities is observed over Europe. In the present study we exploit this effect to analyse aerosol-cloud-radiation interactions. A weekly cy...
An international collaboration of researchers has produced the most detailed map to date of water content in the lower atmosphere. This is the first such map to be made with satellite data and could l...
The simulation of the Antarctic ozone hole by chemistry-climate models
Antarctic ozone hole chemistry-climate models
2009/9/11
While chemistry-climate models are able to reproduce many characteristics of the global total column ozone field and its long-term evolution, they have fared less well in simulating the commonly used ...
Water vapour transport in the tropical tropopause region in coupled Chemistry-Climate Models and ERA-40 reanalysis data
Water vapour transport tropical tropopause region coupled Chemistry-Climate Models
2009/5/6
In this study backward trajectories from the tropical lower stratosphere were calculated for the Northern Hemisphere (NH) winters 1995–1996, 1997–1998 (El Niño) and 1998–1999 (La Niña) a...
Clear sky UV simulations for the 21st century based on ozone and temperature projections from Chemistry-Climate Models
Clear sky UV 21st century ozone and temperature projections Chemistry-Climate Models
2009/3/13
We have estimated changes in surface solar ultraviolet (UV) radiation under cloud free conditions in the 21st century based on simulations of 11 coupled Chemistry-Climate Models (CCMs). The total ozon...
Uncertainties and assessments of chemistry-climate models of the stratosphere

2009/3/10
In recent years a number of chemistry-climate models have been developed with an emphasis on the stratosphere. Such models cover a wide range of time scales of integration and vary considerably in co...
CHEM2D-OPP: A new linearized gas-phase ozone photochemistry parameterization for high-altitude NWP and climate models

2009/1/16
The new CHEM2D-Ozone Photochemistry Parameterization (CHEM2D-OPP) for high-altitude numerical weather prediction (NWP) systems and climate models specifies the net ozone photochemical tendency and its...
Quantitative performance metrics for stratospheric-resolving chemistry-climate models
Quantitative performance metrics stratospheric-resolving chemistry-climate models
2008/11/20
A set of performance metrics is applied to stratospheric-resolving chemistry-climate models (CCMs) to quantify their ability to reproduce key processes relevant for stratospheric ozone. The same metri...
