Entrainment and Detrainment in Cumulus Clouds
Publisher: American Meteorological Society
Abstract: Vertical redistribution of air and its properties inside convective clouds can be studied by standard thermodynamic analyses (Paluch and saturation point diagrams) if the clouds are nonprecipitating and ice free. It is ...
A Simple Model of Droplet Spectral Evolution during Turbulent Mixing
Publisher: American Meteorological Society
Abstract: The mixing of cloudy, saturated air with cloud-free, subsaturated air is examined with a simple one-dimensional model of the mixing process. The model incorporates (i) a one-dimensional parameterization of turbulent ...
The Shape of Things to Come: Why Is Climate Change So Predictable?
Publisher: American Meteorological Society
Abstract: The framework of feedback analysis is used to explore the controls on the shape of the probability distribution of global mean surface temperature response to climate forcing. It is shown that ocean heat uptake, which ...
Notes on a Catastrophe: A Feedback Analysis of Snowball Earth
Publisher: American Meteorological Society
Abstract: The language of feedbacks is ubiquitous in contemporary earth sciences, and the framework of feedback analysis is a powerful tool for diagnosing the relative strengths of the myriad mutual interactions that occur in complex ...
A Midlatitude Cumulus Parameterization that Incorporates Cloudtop Entrainment
Publisher: American Meteorological Society
Abstract: In this paper we present a Kuo-type cumulus parameterization that includes a steady state one-dimensional cloudtop entraining cloud model and ice phase microphysics. Heating profiles computed with this parameterization are ...
Microphysical and Geometrical Controls on the Pattern of Orographic Precipitation
Publisher: American Meteorological Society
Abstract: Patterns of orographic precipitation can vary significantly both in time and space, and such variations must ultimately be related to mountain geometry, cloud microphysics, and synoptic conditions. Here an extension of the ...
Characteristics of Cumulus Band Clouds off the Coast of Hawaii
Publisher: American Meteorological Society
Abstract: We have analyzed aircraft observations from seventeen cumulus cells within cloud bands observed off the east coast of Hawaii during the Joint Hawaii Warm Rain Project (JHWRP) of 1985. Low level convergence generated by the ...
What Controls Stratocumulus Radiative Properties? Lagrangian Observations of Cloud Evolution
Publisher: American Meteorological Society
Abstract: Marine stratocumulus clouds have a large impact on the earth?s radiation budget. Their optical properties vary on two distinct timescales, one associated with the diurnal cycle of solar insolation and another with the ...
