THE INFLUENCE OF FINITE OBSERVATION INTERVALS ON THE MEASUREMENT OF TURBULENT DIFFUSION PARAMETERS
Publisher: American Meteorological Society
Abstract: The correlation functions obtained from truncated samples are expressed in terms of the sampling length and the correlation functions of the basic stationary random variables. The application of the results to diffusion ...
Numerical Simulation of the Development of the Intermediate-Scale Cyclone in a Moist Model Atmosphere
Publisher: American Meteorological Society
Abstract: The genesis and development of an intermediate-scale cyclone in middle latitudes was simulated numerically and its three-dimensional structure analysed. A six-level moist primitive equation model was run for a channel flow ...
A Numerical Shallow-Fluid Model Including Orography with a Variable Grid
Publisher: American Meteorological Society
Abstract: A system of shallow-fluid equations on the rotating earth is integrated numerically as an initial and boundary value problem for air flow across a mountain barrier. The fluid is confined in a channel bounded by two parallel ...
The Development of Warm Rain in a Cumulus Model
Publisher: American Meteorological Society
Abstract: A one-and-a-half-dimensional, time-dependent cloud model proposed by the authors is extended to investigate warm-rain formation. A total of 61 mass categories, corresponding to radii from 4 ?m to 4 mm, are used to determine ...
Response of Tradewind Cumuli to Large-Scale Processes
Publisher: American Meteorological Society
Abstract: The two-dimensional slab-symmetric numerical cloud model used by Soong and Ogura (1973) for studying the evolution of an isolated cumulus cloud is extended to investigate the statistical properties of cumulus clouds which ...
Boundary-Layer Forcing as a Possible Trigger to a Squall-Line Formation
Publisher: American Meteorological Society
Abstract: The study of the life history of the 8 June 1966 squall line by Ogura and Chen (1977) indicates that a well-defined narrow hand of horizontal convergence was present at low levels prior to the appearance of first radar ...
Large-Scale Influences Upon the Generation of a Mesoscale Disturbance
Publisher: American Meteorological Society
Abstract: A case of squall line generation in the National Severe Storms Laboratory (NSSL) network has been examined with the intention of capturing synoptic-scale influences. A telescopic analysis approach was used whereby observations ...
On the Formation of Organized Convective Systems Observed over the Eastern Atlantic
Publisher: American Meteorological Society
Abstract: Surface and upper air data gathered from a dense network of ship observations during the GARP Atlantic Tropical Experiment (GATE) were analyzed to correlate the upward motion with organized cloud convection. Two periods ...
