Cirrus cloud radiative forcing
WebSep 1, 1994 · If the observed solar cloud forcing in excess of 100 W-m −2 is to be attributed to cirrus anvils alone, then the optical depth of these anvils must be at least 5 (assuming 50% cloud cover and an ice crystal effective radius of 15 µm). The net radiative forcing of cirrus near the tropical tropopause is positive (heating) for cloud optical ...

WebMammatus (also called mamma or mammatocumulus, meaning "mammary cloud") is a cellular pattern of pouches hanging underneath the base of a cloud, typically a cumulonimbus raincloud, although they may be attached to other classes of parent clouds. The name mammatus is derived from the Latin mamma (meaning "udder" or "breast").. … WebApr 13, 2024 · This cloud radiative forcing is observed partly over the cold tongue in sea surface temperature (SST) in the South China Sea. Numerical simulations with a 1-dimensional slab ocean model suggests that the monsoon-induced UT cloud radiative forcing contributes partially to maintain and reinforce the SST cold tongue with a …
Webcloud types considered in Chen et al (2000), cirrus clouds (visible optical depth <3.6, cloud top pressure <440 mb) had the greatest impact on top-of-atmosphere (TOA) longwave fluxes and had a global annual mean net warming of +1.3Wm−2.
