RISGeographical Distribution of Variance of Intraseasonal Variations in Western Indochina as Revealed from Radar Reflectivity Data
Publisher: American Meteorological Society
Abstract: This study reveals remarkable differences in the geographical distribution of variance between two types of intraseasonal variations in daily-mean radar reflectivity data in the western part of the Indochina Peninsula. In ...
Secondary Generation of Gravity Waves Associated with the Breaking of Mountain Waves
Publisher: American Meteorological Society
Abstract: The generation of small-scale gravity waves associated with the breaking of mountain waves in the stratosphere has been simulated within a fully compressible, nonhydrostatic, two-dimensional numerical model. The model ...
Numerical Experiments on the Mechanisms for the Development and Maintenance of Long-Lived Squall Lines in Dry Environments
Publisher: American Meteorological Society
Abstract: The mechanisms responsible for the development and maintenance of long-lived squall lines in dry environments are investigated through two-dimensional numerical experiments by using a nonhydrostatic cloud model. The squall ...
Westward Generation of Eastward-Moving Tropical Convective Bands in TOGA COARE
Publisher: American Meteorological Society
Abstract: Mechanisms responsible for westward generation of eastward-moving tropical convective bands in the Tropical Ocean and Global Atmosphere Coupled Ocean?Atmosphere Response Experiment (TOGA COARE) are investigated using a ...
An Observational Study of Intraseasonal Variations over Southeast Asia during the 1998 Rainy Season
Publisher: American Meteorological Society
Abstract: In the present study, intraseasonal variations of precipitation over Thailand [Thailand daily rainfall (TDR)] during 1998 and the accompanying variations of the tropospheric circulation are analyzed, mainly with the use ...
Mechanisms of the Northward Movement of Submonthly Scale Vortices over the Bay of Bengal during the Boreal Summer
Publisher: American Meteorological Society
Abstract: Mechanisms of the northward movement of submonthly scale vortices over the Bay of Bengal during the boreal summer (May?September) are studied with the use of a vorticity budget analysis applied to the ECMWF 40-yr Re-Analysis ...
Nonhydrostatic Atmospheric Modeling Using a Combined Cartesian Grid
Publisher: American Meteorological Society
Abstract: A new method for representing topography on a Cartesian grid is applied to a two-dimensional nonhydrostatic atmospheric model to achieve highly precise simulations over steep terrain. The shaved cell method based on ...
Climatological Characteristics of the Intraseasonal Variation of Precipitation over the Indochina Peninsula
Publisher: American Meteorological Society
Abstract: With the use of daily rain gauge data observed at 210 stations in the Indochina Peninsula (ICP) for the 26 yr from 1978 to 2003, this paper describes climatological characteristics of 2 types of intraseasonal variations ...
Flow Regimes of Nonlinear Heat Island Circulation
Publisher: American Meteorological Society
Abstract: Previous laboratory and numerical experiments show that the nonlinear heat island circulation has two different flow regimes: One has two maximums of updraft at both edges of the heat island (type E), while the other has ...
