Atmospheric Turbulence: A Cloud Droplet's View

 

 

The earth's atmosphere is characterized by exceedingly large Reynolds numbers and, as a result, turbulence is ubiquitous there. In this talk we will take a look at the nature of atmospheric turbulence from a cloud droplet's perspective, asking how turbulence influences the evolution of cloud droplet size distributions. We care about these size distributions because they determine macroscopic cloud properties such as precipitation efficiency and optical thickness and, therefore, influence the earth's climate. Specifically, I will discuss recent efforts toward understanding intermittency in kinetic energy dissipation, including the cloud droplet response and related thermodynamic feedback.
