Query: Cumulus Parameterization: Those Who Can Remember the Past Are Condemned
  to Repeat It   Moist convection plays a leading role in the dynamics and energy budget of
Earth's tropics and influences the sensitivity of Earth's climate to greenhouse
gas increases. Because individual convective cells are much smaller than the
gridboxes of 3-dimensional global climate models (GCMs), these models
parameterize the effects of an ensemble of moist convective updrafts and
downdrafts on the environment. Cumulus parameterization has been a focus of the
terrestrial meteorology community for half a century. Only in past decade,
however, have GCMs with moist convective physics been applied to other planets.
Given our lack of detailed knowledge about convective clouds except on Earth,
planetary GCMs are often designed with very simple approaches to cumulus
parameterization, adopted from the earliest generations of terrestrial GCMs.
These parameterizations were based on breakthroughs in understanding of
convection in their time. However, at the same time that planetary GCMs have
begun to emerge, a quiet revolution in how we think about terrestrial
convection has started to influence the design of terrestrial GCMs. In this
paper we review how some of the assumptions in the classical cumulus
parameterizations used in planetary GCMs (and still in some terrestrial GCMs)
have given way in recent years to a deeper understanding of how convection
operates and why it matters for atmospheric dynamics and climate - on any
planet.
