In HadGEM2-A, AMIP experiments forced with observed sea surface temperatures respond to uniform and patterned ?4 K SST perturbations with strong positive cloud feedbacks in the subtropical stratocumulus/trade cumulus transition regions. Over the subtropical Northeast Pacific at 137 W/26 N, the boundary layer cloud fraction reduces considerably in the AMIP ?4 K patterned SST experiment. The near...

The aerosol direct radiative effect (DRE) of African smoke was analyzed in cloud scenes over the southeast Atlantic Ocean, using Scanning Imaging Absorption Spectrometer for Atmospheric Chartography (SCIAMACHY) satellite observations and Hadley Centre Global Environmental Model version 2 (HadGEM2) climate model simulations. The observed mean DRE was about 30–35 W m−2 in August and September 200...

The objective of this study was to compare between measured weather data (2010-2019) and projected for the same period obtained from three global climate models (HadGEM2-ES, CSIRO-Mk3-6-0, MIROC5), with its four RCPs scenarios (RCP2.6, RCP4.5, RCP6.0 RCP8.5) developed five agro climatic zones Egypt determine most suitable scenario be used in each agro-climatic zone projection effect change futu...

A new generation of an Earth system model now includes a number of land-surface processes directly relevant to analyzing potential impacts of climate change. This model, HadGEM2-ES, allows us to assess the impacts of climate change, multiple interactions, and feedbacks as the model is run. This paper discusses the results of centuryscale HadGEM2-ES simulations from an impacts perspective – spec...
