英文摘要: This study examines cloud responses to global warming using a global nonhydrostatic model with two different cloud microphysics schemes. The cloud microphysics schemes tested here are the single- and doublemoment schemes with six water categories: these schemes are referred to as NSW6 and NDW6, respectively. Simulations of one year for NSW6 and one boreal summer for NDW6 are performed using the nonhydrostatic icosahedral atmospheric model with a mesh size of approximately 14 km. NSW6 and NDW6 exhibit similar changes in the visible cloud fraction under conditions of global warming. The longwave (LW) cloud radiative feedbacks inNSW6 and NDW6are within the upper half of the phase 5 of the CoupledModel Intercomparison Project (CMIP5)-Cloud Feedback Model Intercomparison Project 2 (CFMIP2) range. The LWcloud radiative feedbacks are mainly attributed to cirrus clouds, which prevail more in the tropics under global warming conditions. For NDW6, the LW cloud radiative feedbacks from cirrus clouds also extend to midlatitudes. The changes in cirrus clouds and their effects on LW cloud radiative forcing (LWCRF) are assessed based on changes in the effective radii of ice hydrometeors (Rei) and the cloud fraction. Itwas determined that an increase in Rei has a nonnegligible impact on LWCRF compared with an increase in cloud fraction. © 2016 American Meteorological Society. 资助项目: JAMSTEC, Japan Agency for Marine-Earth Science and Technology
