More intense and frequent thunderstorms linked to global climate variability
large thunderstorms climate variability global climate change
2021/8/4
Large thunderstorms in the Southern Great Plains of the U.S. are some of the strongest on Earth. In recent years, these storms have increased in frequency and intensity, and new research shows that th...
Optimization of a prognostic biosphere model for terrestrial biomass and atmospheric CO2 variability
prognostic biosphere model terrestrial biomass atmospheric CO2 variability
2014/12/19
This study investigates the capacity of a prognostic biosphere model to simulate global variability in atmospheric CO2 concentrations and vegetation carbon dynamics under current environmental conditi...
The role of phytoplankton dynamics in the seasonal and interannual variability of carbon in the subpolar North Atlantic – a modeling study
phytoplankton dynamics seasonal interannual variability carbon subpolar North Atlantic modeling study
2014/12/10
We developed an ecosystem/biogeochemical model system, which includes multiple phytoplankton functional groups and carbon cycle dynamics, and applied it to investigate physical-biological interactions...
Simulating Southern Hemisphere extra-tropical climate variability with an idealised coupled atmosphere-ocean model
Model In the southern hemisphere Winter atmospheric circulation Lateral resolution Coupling Ocean circulation patterns Resolution Simplified physical The coupled model
2014/12/10
A quasi-geostrophic model of Southern Hemisphere's wintertime atmospheric circulation with horizontal resolution T21 has been coupled to a global ocean circulation model with a resolution of 2° × 2° a...

Coupling Transport models Lagrangian particle dispersion models Gas The ground emissions Traffic observation sites
2014/12/9
This study assesses the advantages of using a coupled atmospheric-tracer transport model, comprising a global Eulerian model and a global Lagrangian particle dispersion model, to improve the reproduci...
The identification of a solar signal in climate records of the last 500 years using proxy and model-based analysis and the implications for natural climate variability
Satellite instruments car the solar constant solar energy output climate the climate warming
2014/10/22
There has been confirmation in the last two decades, through instrumental measurements onboard satellites, that the 'solar constant' does, as has long been hypothesized, vary. While there is no consen...
Holocene Paleo-environmental Variability Reconstructed from a Lake Sediment Record from Southeast Greenland
Holocene Paleoenvironmental Variability Reconstructed a Lake Sediment Record Southeast Greenland
2014/10/21
Arctic climate variability over the Holocene has been both extensive and, at times, abrupt. Current understanding of these changes is still quite limited with few highresolution paleoclimate records a...

Holocene Climatic Variability Sermilik Valley Southeast Greenland Lake Sediments
2014/10/21
During the latter half of the 20th century until present day there has been an unprecedented rise in global annual mean temperatures accompanied by rising sea levels and a decrease in Northern Hemisph...
Intra-Seasonal Variability of Aerosols and Their Radiative Impacts on Sahel Climate during the Period 2000-2010 Using AERONET Data
AERONET Aerosol Optical Depth Radiative Forcing
2013/3/11
This paper presents a study using in situ measurements (AERONET data) to characterize the intra-seasonal variability of aerosols and their shortwave radiative impacts on Sahel (11N - 18N and 20W - 15E...
