Orographic cirrus in the global climate model ECHAM5

NettetGCMs are the cirrus forced by orographic gravity waves. It has been shown that these orographic cirrus can be better representeby coupling the cirrus d forcing to the orographic gravity wave scheme (Dean et al., 2007; Joos et al., 2008Nevertheless, even away from orography cirrus ). clouds are typically not well simulated by GCMs. Nettet25. jun. 2004 · Our simulations emphasize that the median cirrus particle sizes peak in the radius range of 10–20 μm, mainly resulting from the small-scale gravity wave forcing of cirrus formation.
