Permitted paths of cloud evolution in thermodynamical phase-space
Abstract
A study is conducted, for studying the characteristics and temporal evolution of warm cloud fields. The Hawaiian and Mediterranean cloud fields are simulated using the RAMS6 model. The cloud field evolution is examined in time and space, in terms of thermodynamical phase-space. We show that clouds occupy limited subspace, defined by the environmental conditions. The allowed phase-space traces can characterize the evolution in time of a single cloud, or the simultaneous states of many clouds in the field. The method presents a new tool for tracing cloud evolution and for separation of the influence of the meteorological conditions on the field from the aerosol effect.
