Collaborative research at the intersection of weather and climate by Mitchell

Fundamental barriers to advancing weather and climate diagnosis and prediction on time-scales from days to years are partly attributable to gaps in knowledge and the limited capability of contemporary operational and research numerical prediction systems to represent precipitating convection and its multiscale organization, particularly in the tropics. In this regard improvements in convective parameterization have not kept pace with improvements in knowledge gained from process studies of convective organization. As convective organization is not represented by contemporar y parameterizations, the large-scale effects of convective organization have, therefore, yet to be properly assessed. Examples of tropical phenomena in which the multi-scale organization of convection is a key process are:
