Global consequences of interactions between clouds and radiation at scales unresolved by global climate models

Horizontal grid‐spacings in conventional atmospheric general circulation models (GCMs) are typically between 100 km and 500 km. Hence, many processes are unresolved and must be parameterized in terms of resolved variables. Development of satisfactory parameterizations of mean‐field (or domain‐average) cloud and radiative processes has been frustratingly slow. Moreover, the sensitivity of conventional GCMs to unresolved interactions between …
