Daidaitawar radiative-convective

Daidaitawar radiative-convective (RCE) ra'ayi ne na ma'aunin radiative na yanayi. Ya bayyana ma'auni tsakanin sanyaya na radiative longwave da dumama saboda convection da yaduwar ƙasa. Babban bambanci ga daidaitattun radiative mai tsabta shine cewa an daidaita ƙimar raguwa a cikin troposphere zuwa mafi mahimmanci.

A cikin samfuran yanayi, ana amfani da manufar don kwaikwayon matsakaicin tsarin zafi na duniya kuma yana ba da damar nazarin ƙwarewar wannan tsarin ga CO2. Syukuro Manabe ya lashe kyautar Nobel ta Physics don samfurinsa na RCE kamar yadda shi ne na farko da ya samar da ƙididdigar gaskiya game da Yanayin Yanayi na Duniya (ECS) .  A Duniya, yanayin zafi yana kan ma'auni da yawa kusa da RCE. Sabili da haka, an kuma yi amfani da manufar don nazarin yaduwar wurare masu zafi da fannoni daban-daban na convection mai laushi Jakob, Singh and Jungandreas (2019).
