Description of Mixed-Phase Clouds in Weather Forecast and Climate Models

Abstract

LONG-TERM GOALS: To develop an improved parameterization of so-called mixed-phase stratocumulus in numerical models of weather and climate, and of their impact on the surface energy budget over the Arctic Ocean, their impact on the vertical structure of the lower troposphere and relationships to larger scale meteorology. OBJECTIVES: Develop a process-level understanding on why so-called mixed-phase stratocumulus are so common, by far the most common type of clouds in the Arctic, when basic thermodynamics seems to suggest that ice and liquid particles cannot coexist for long times. Find linkages between dynamic processes on all scales, ranging from long range transport to turbulent motions, and cloud micro-physics.
