Tightening of tropical ascent and high clouds key to precipitation change in a warmer climate
The change of global-mean precipitation under global warming and interannual variability is predominantly controlled by the change of atmospheric longwave radiative cooling. Here we show that tightening of the ascending branch of the Hadley Circulation coupled with a decrease in tropical high cloud fraction is key in modulating precipitation response to surface warming. The magnitude of high cl...
متن کاملRelative humidity changes in a warmer climate
[1] Key climate feedback due to water vapor and clouds rest largely on how relative humidity R changes in a warmer climate, yet this has not been extensively analyzed in models. General circulation models (GCMs) from the CMIP3 archive and several higher‐ resolution atmospheric GCMs examined here generally predict a characteristic pattern of R trend with global temperature that has been reported...
متن کاملChanges in winter precipitation extremes for the western United States under a warmer climate as simulated by regional climate models
[1] We find a consistent and statistically significant increase in the intensity of future extreme winter precipitation events over the western United States, as simulated by an ensemble of regional climate models (RCMs) driven by IPCCAR4 global climate models (GCMs). All eight simulations analyzed in this work consistently show an increase in the intensity of extreme winter precipitation with ...
متن کاملDelayed Seasonal Cycle and African Monsoon in a Warmer Climate
Increasing greenhouse gases will change many aspects of the Earth’s climate, from its annual mean to the frequency of extremes such as heat waves and droughts[1]. Here we report that the current generation of climate models predicts a delay in the seasonal cycle of global rainfall and ocean temperature in response to increasing greenhouse gases, with important implications for the regional mons...
متن کاملWill Extratropical Storms Intensify in a Warmer Climate?
Extratropical cyclones and how they may change in a warmer climate have been investigated in detail with a high-resolution version of the ECHAM5 global climate model. A spectral resolution of T213 (63 km) is used for two 32-yr periods at the end of the twentieth and twenty-first centuries and integrated for the Intergovernmental Panel on Climate Change (IPCC) A1B scenario. Extremes of pressure,...
