Two-and Three-Dimensional Modelling Studies of the Big Thompson Storm
Publisher: American Meteorological Society
Abstract: The Big Thompson storm occurred on 31 July?1 August 1976 over Big Thompson Canyon, Colorado, when a secondary cold frontal surge was accelerated and reached the foothills of the Front Range. Two- and three-dimensional moist ...
Numerical Study of OrograPhic-Convective Precipitation over the Eastern Arabian Sea and the Ghat Mountains during the Summer Monsoon
Publisher: American Meteorological Society
Abstract: When the western coast of India lies in the path of the low-level west-southwest wind crossing the Arabian Sea during the summer monsoon season, deep convection frequently develops over the ocean off the coast. In such a ...
Effects of Orographically Forced Upstream Lifting on Mesoscale Heavy Precipitation: A Case Study
Publisher: American Meteorological Society
Abstract: An exceptionally heavy rainstorm hit the coastal area of the western part of Japan on 23 July 1983. The 6-h rainfall accumulation exceeded 300 mm locally. At its peak period, the hourly precipitation rate was as high as ...
Structure of the Cold Front Observed in SESAME-AVE III and its Comparison with the Hoskins-Bretherton Frontogenesis Model
Publisher: American Meteorological Society
Abstract: A cold front which passed through the dense network of the SESAME-AVE (Severe Environmental Storms and Mesoscale Experiment?Atmospheric Variability Experiment) on 25?26 April 1979 was investigated. Rawinsonde data collected ...
A Modeling Case Study of Interaction between Heavy Precipitation and a Low-Level Jet over Japan in the Baiu Season
Publisher: American Meteorological Society
Abstract: This paper presents results of simulations for a case of heavy precipitation that occurred on 23 July 1982 over western Japan. Special emphasis is placed on synoptic- and subsynoptic-scale processes that led to heavy ...
Numerical Simulation of a Midlatitude Squall Line in Two Dimensions
Publisher: American Meteorological Society
Abstract: A two-dimensional, anelastic cloud model was used in attempts to numerically replicate the observed structure of a midlatitude squall line. Initial conditions were adapted from observations of the 22 May 1976 Oklahoma line. ...
Effect of Vertical Wind Shear on Numerically Simulated Multicell Storm Structure
Publisher: American Meteorological Society
Abstract: A strictly two-dimensional cloud model was used to gauge the effect of vertical wind shear on the mature phase behavior of model-simulated multicellular storms, extending the previous work of the authors. We specifically ...
An Observational Study of Easterly Waves over the Eastern Pacific in the Northern Summer Using FGGE Data
Publisher: American Meteorological Society
Abstract: FGGE revel III-b data provided by the European Centre for Medium-Range Weather Forecasts and the outgoing longwave radiation data measured by satellites are used to investigate observationally relationships between deep ...
The Structure of a Midlatitude Squall Line: A Case Study
Publisher: American Meteorological Society
Abstract: On 22 May 1976 a well-organized squall line with a width of more than 100 km passed through the mesonetwork of the National Severe Storms Laboratory in central Oklahoma. This squall line was evolving from its mature stage ...
Modeling the Evolution of the Convective Planetary Boundary Layer
Publisher: American Meteorological Society
Abstract: The level 3 turbulence closure model proposed by Mellor and Yamada (1974) is modified 1) to incorporate the formulations for the turbulence third-order moments and pressure terms proposed by Zeman and Lumley (1976) and 2) ...
