At a minimum, one would need to argue for a distinction between tropical mean trends and trends in the
regions of deep convection.
The researchers plan to incorporate information from the cloud - resolving model simulations that have been evaluated against observations in this study into climate model
parameterizations of deep convection using probability distribution functions of environmental factors.
Although the polynya has aroused continued interest1, 2,3,4,5,6,7,8,9, the presence of a fresh surface layer has prevented the recurrence
of deep convection there since 19768, and it is now largely viewed as a naturally rare event10.
The links between model biases and the underlying assumptions of the shallow cumulus scheme are further diagnosed with the aid of large - eddy simulations and aircraft measurements, and by suppressing the
triggering of the deep convection scheme.

Role of deep convection in establishing the isotopic composition of water vapor in the tropical transition layer.
The animation showed on Sept. 14 that Ian remains a sheared tropical storm, with the low - cloud center exposed to the south of the main
area of deep convection and developing strong thunderstorms.
