Modeled rapid adjustments in diurnal temperature range response to CO2 and solar forcings

New open access IAGP paper in Journal of Geophysical Research: Atmospheres Modeled rapid adjustments in diurnal temperature range response to CO2 and solar forcings Climate models from the National Centre of Atmospheric Research were used to determine if rapid adjustments to surface heat fluxes contribute to a changes in diurnal temperature range (DTR) under 2 x CO2 and -2% solar forcings.   An ensemble of model runs was employed with locations selected to represent a range of different climatic conditions and with forcing implemented hourly throughout the diurnal cycle. The change in skin surface DTR and surface energy fluxes during the 3 days after forcing were used to quantify the rapid adjustment response and temperature related feedback. Averaged over all locations, skin surface DTR reduced by 0.01°C after CO2 forcing and included a rapid adjustment to skin surface DTR of -0.12°C. Skin surface DTR reduced by 0.17°C after solar forcing and included a rapid adjustment of -0.01°C. DOI: 10.1002/jgrd.50243 Authors: L.S. Jackson; P.M.
