Idealized Model for Equilibrium Boundary Layer over Land
Publisher: American Meteorological Society
Abstract: An idealized equilibrium mixed layer (ML) model is used to explore the coupling between the surface, the ML, and the atmosphere above. It shows that ML depth increases as vegetative resistance to evaporation increases. The ...
Understanding Hydrometeorology Using Global Models
Publisher: American Meteorological Society
Abstract: The land surface coupling, a crucial element of the climate system, is explored in the recent 40-yr European Centre for Medium-Range Forecasts (ECMWF) reanalysis (ERA-40) model. In seasonal forecasts for the Northern ...
Thermodynamic Classification of Tropical Convective Soundings
Publisher: American Meteorological Society
Abstract: Soundings from a land tropical experiment (VIMHEX II) are classified according to local area rainfall into four regimes depicting the transition from dry to highly disturbed days. The thermodynamic structure for each of ...
A Relationship Between Stratification, Cloud Depth, and Permitted Cloud Radii
Publisher: American Meteorological Society
Abstract: A one-dimensional cumulus model is used to interrelate cloud radius, stratification and cloud height. It is suggested that if only certain ranges of cloud height and radius are permitted, then from the stratification, one ...
Thermodynamics of Mixed Stratocumulus Layers: Saturation Point Budgets
Publisher: American Meteorological Society
Abstract: Saturation point (SP) diagrams and a circulation model are used to analyze the thermodynamics of mixed stratocumulus layers, and develop conceptual tools for observational and parametric analyses. These models show the ...
Mixing Line Analysis of Clouds and Cloudy Boundary Layers
Publisher: American Meteorological Society
Abstract: The diagnostic study of the thermodynamic structure of nonprecipitating clouds and cloudy boundary layers is formulated using a mixing line and saturation point approach. A parametric model for the mean structure is developed ...
Boundary Layer Thermodynamics of a High Plains Severe Storm
Publisher: American Meteorological Society
Abstract: A new analysis method based on air parcel saturation point is used to intercompare data sampled by different systems (aircraft, rawinsondes, and a surface mesonet) during the passage of one severe storm in the 1981 Cooperative ...
Saturation Point Analysis of Moist Convective Overturning
Publisher: American Meteorological Society
Abstract: A unified approach to the thermodynamics of cloudy air, cloud-clear air mixing processes, atmospheric thermodynamic equilibrium structure and instability is formulated, using a new concept: the Saturation Point. This permits ...
Cloud Thermodynamic Models in Saturation Point Coordinates
Publisher: American Meteorological Society
Abstract: One-dimensional thermodynamic models for cloud-environment mixing, evaporation into downdrafts and precipitation from updrafts are presented in a parallel treatment using convective pressure scales and saturation point ...
