Clouds, Climate and Extreme Weather Research

Climate and Extreme Weather Research

driven by the SPACE AROUND YOU

Given the current level of understanding of phenomena like hurricanes, extratropical cyclones, and severe thunderstorms-which result from complex interactions between many scales of motion in the atmosphere-it is difficult to skillfully predict if these weather phenomena will become something extraordinary ; a similar statement may be made for events such as an extended heat wave or seasonal flooding. Adding a sense of urgency to this already complicated problem are projections of more frequent, and perhaps more intense extreme events in future climates. The Department of Earth, Atmospheric and Planetary Sciences is responding to this problem through its focus on Clouds, Climate and Extreme Weather (C-CLEW), which seeks to... Understand and predict the physical and statistical behavior of extreme weather and climate events.

Droplet trajectories within a 3D numerical simulation of the turbulent kinetic energy (TKE) field within a growing cumulus cloud. Droplets can grow faster by collection of  other droplets in regions of high TKE (pink regions of cloud, with present valus given by "hotness" of dot color), but this growth will be most efective in speeding rain formation if they then subsequently enter regions of greater cloud water (denoted by warm colors along trajectory).
