===Convection===
Moist convection releases latent heat and is important to the Earth's energy budget. Convection occurs on too small a scale to be resolved by climate models, and hence it must be handled via parameters. This has been done since the 1950s. Akio Arakawa did much of the early work, and variants of his scheme are still used,<ref>{{cite web |url=http://www.aip.org/history/climate/arakawa.htm |title=Arakawa's Computation Device |publisher=Aip.org |access-date=2012-02-18 |archive-date=15 June 2006 |archive-url=https://web.archive.org/web/20060615032539/http://www.aip.org/history/climate/arakawa.htm |url-status=dead }}</ref> although a variety of different schemes are now in use.<ref>{{cite web |url=http://grads.iges.org/reps/rep27/colarep27.html |title=COLA Report 27 |publisher=Grads.iges.org |date=1996-07-01 |access-date=2012-02-18 |url-status=dead |archive-url=https://web.archive.org/web/20120206085956/http://grads.iges.org/reps/rep27/colarep27.html |archive-date=6 February 2012}}</ref><ref>{{cite web|url=http://www-pcmdi.llnl.gov/projects/modeldoc/amip/10Tbl2.10.html |title=Table 2-10 |publisher=Pcmdi.llnl.gov |access-date=2012-02-18}}</ref><ref>{{cite web |url=http://rainbow.llnl.gov/projects/modeldoc/cmip/table4.html |title=Table of Rudimentary CMIP Model Features |publisher=Rainbow.llnl.gov |date=2004-12-02 |access-date=2012-02-18 |archive-date=15 May 2006 |archive-url=https://web.archive.org/web/20060515195016/http://rainbow.llnl.gov/projects/modeldoc/cmip/table4.html |url-status=dead }}</ref> Clouds are also typically handled with a parameter, for a similar lack of scale. Limited understanding of clouds has limited the success of this strategy, but not due to some inherent shortcomings of the method.<ref>{{cite web |url=http://www.aip.org/history/climate/GCM.htm |title=General Circulation Models of the Atmosphere |publisher=Aip.org |access-date=2012-02-18 |archive-date=30 July 2012 |archive-url=https://web.archive.org/web/20120730192534/http://www.aip.org/history/climate/GCM.htm |url-status=dead }}</ref>
