Understanding the Covariance of Microphysics, Thermodynamics, and Dynamics in Mixed Phase Clouds using Airborne Measurements
Abstract
The physical processes responsible for cloud initiation and lifecycle are complex and involve the interaction between the microphysics, thermodynamics, and dynamics of the atmosphere. Representation of these processes in models requires understanding of the covariance of important parameters at scales that are difficult to resolve in models. We utilize aircraft based measurements in mixed phase clouds to examine the relationship of ice phase partitioning and microphysics with thermodynamic properties and vertical motion. Results are compiled from observational data obtained in convective mixed phase clouds during the Calwater and Two Column Aerosol Project (TCAP) field campaigns conducted using the Department of Energy Gulfstream-1 aircraft. Our results provide a basis for building statistical relationships between microphysical, thermodynamic, and dynamic properties in clouds that are useful for model development and evaluation.
