Future changes of global potential evapotranspiration simulated from CMIP5 to CMIP6 models

Robust Hadley Circulation changes and increasing global dryness due to CO2 warming from CMIP5 model projections.

In this paper, we investigate changes in the Hadley Circulation (HC) and their connections to increased global dryness (suppressed rainfall and reduced tropospheric relative humidity) under CO2 warming from Coupled Model Intercomparison Project Phase 5 (CMIP5) model projections. We find a strengthening of the HC manifested in a "deep-tropics squeeze" (DTS), i.e., a deepening and narrowing of th...

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...

Robust Wind and Precipitation Responses to the Mount Pinatubo Eruption, as Simulated in the CMIP5 Models

The volcanic eruption of Mount Pinatubo in June 1991 is the largest terrestrial eruption since the beginning of the satellite era. Here, the monthly evolution of atmospheric temperature, zonal winds, and precipitation following the eruption in 14 CMIP5 models is analyzed and strong and robust stratospheric and tropospheric circulation responses are demonstrated in both hemispheres, with troposp...

Detection of global runoff changes: results from observations and CMIP5 experiments

This paper assesses the detectability of changes in global streamflow. First, a statistical detection method is applied to observed (no missing data which represent 42 % of global discharge) and reconstructed (gaps are filled in order to cover a larger area and about 60 % of global discharge) streamflow. Observations show no change over the 1958–1992 period. Further, an extension to 2004 over t...

Global warming and the weakening of the Asian summer monsoon circulation: assessments from the CMIP5 models
