Systematic land climate and evapotranspiration biases in CMIP5 simulations
[1] Land climate is important for human population since it affects inhabited areas. Here we evaluate the realism of simulated evapotranspiration (ET), precipitation, and temperature in the CMIP5 multimodel ensemble on continental areas. For ET, a newly compiled synthesis data set prepared within the Global Energy and Water Cycle Experiment-sponsored LandFlux-EVAL project is used. The results r...
متن کاملSouthern Hemisphere Cloud–Dynamics Biases in CMIP5 Models and Their Implications for Climate Projections
This study quantifies cloud–radiative anomalies associated with interannual variability in the latitude of the SouthernHemisphere (SH)midlatitude eddy-driven jet, in 20 global climatemodels fromphase 5 of theCoupled Model Intercomparison Project (CMIP5). Two distinct model types are found. In the first class ofmodels (type I models), total cloud fraction is reduced at SHmidlatitudes as the jet ...
متن کاملENSO Asymmetry in CMIP5 Models
The El Ni~ no–La Ni~ na asymmetry is evaluated in 14 coupled models from phase 5 of the Coupled Model Intercomparison Project (CMIP5). The results show that an underestimate of ENSO asymmetry, a common problem noted in CMIP3 models, remains a common problem in CMIP5 coupled models. The weaker ENSO asymmetry in the models primarily results from a weaker SST warm anomaly over the eastern Pacific ...
متن کاملSouthern Hemisphere jet latitude biases in CMIP5 models linked to shortwave cloud forcing
[1] Substantial biases in shortwave cloud forcing (SWCF) of up to 30 W m 2 are found in the midlatitudes of the Southern Hemisphere in the historical simulations of 34 CMIP5 coupled general circulation models. The SWCF biases are shown to induce surface temperature anomalies localized in the midlatitudes, and are significantly correlated with the mean latitude of the eddy-driven jet, with a neg...
متن کاملSeasonal and regional biases in CMIP5 precipitation simulations
This study provides insight into how CMIP5 climate models perform in simulating summer and winter precipitation at different geographical locations and climate conditions. Precipitation biases in the CMIP5 historical (1901 to 2005) simulations relative to the Climatic Research Unit (CRU) observations are evaluated over 8 regions exhibiting distinct seasonal hydroclimates: moist tropical (Amazon...
