Model peredaran am (GCM) ialah model matematik bagi peredaran am bagi sesebuah atmosfera atau lautan planet dan berdasarkan persamaan Navier–Stokes]] di atas sebuah sfera berputar dengan dengan istilah termodinamik untuk pelbagai sumber tenaga (sinaran, haba pendam). Persamaan ini ialah dasar untuk program komputer kompleks biasanya digunakan untuk mensimulasi atmosfera atau lautan Bumi. GCM atmosfera dan lautan (AGCM dan OGCM) ialah komponen kekunci bagi model iklim global bersama dengan air batu laut dan komponen permukaan darat. GCM dan model iklim global digunakan secara meluas untuk peramalan cuaca, pemahaman iklim, dan pengunjuran perubahan iklim. Versi-versi yang direka untuk aplikasi iklim skala masa dekad hingga abad pada asalnya dicipta oleh Syukuro Manabe dan Kirk Bryan di Makmal Dinamik Bendalir Geofizikal di Princeton, New Jersey.[1] These computationally intensive numerical models are based on the integration of a variety of fluid dynamical, chemical, and sometimes biological equations.
