Forecasting Tropical Cyclone Motion Using a Discriminant Analysis Procedure
Publisher: American Meteorological Society
Abstract: A general method of objective tropical cyclone guidance is proposed in which the forecast variables are categories of tropical cyclone motion. Using this approach, information on more than one scenario is presented, a ...
Synoptic-Scale Modulation of Convection during the Australian Summer Monsoon
Publisher: American Meteorological Society
Abstract: Time-longitude representations of Japanese Geostationary Meteorology Satellite (GMS) infrared imagery indicate the existence of major synoptic-scale banding of convection within the Australian summer monsoon. This bands ...
A Comparison of Tropical Cyclone, Hurricane and Typhoon Mass and Moisture Structure
Publisher: American Meteorological Society
Abstract: Radiosonde soundings obtained within 180 km of tropical cyclones in the Australian region are compared to similar sets of hurricane and typhoon data. The mean storm profiles in each region reflect the background structure ...
Propagation and Diurnal Evolution of Warm Season Cloudiness in the Australian and Maritime Continent Region
Publisher: American Meteorological Society
Abstract: Warm season cold cloud-top climatology in the Austral?Indonesian region is examined for evidence of propagating modes of precipitation that originate from elevated heat sources and the diurnal heating cycle. Using ...
Radar Characteristics of Storms in the Sydney Area
Publisher: American Meteorological Society
Abstract: The characteristics of radar echoes for 12 thunderstorm days in the vicinity of Sydney, Australia, in the summer of 1995/96 have been examined using an objective methodology for storm identification and tracking. The spatial ...
The Influence of System Parameters on Acoustic Sounding
Publisher: American Meteorological Society
Abstract: Acoustic radar records are reproduced to show the effects which may result from varying system parameters such as transmitted power, pulse length, pulse repetition frequency and recording techniques. Improved results can ...
Polarimetric Radar Observations of the Persistently Asymmetric Structure of Tropical Cyclone Ingrid
Publisher: American Meteorological Society
Abstract: Tropical Cyclone Ingrid had a distinctly asymmetric reflectivity structure with an offshore maximum as it passed parallel to and over an extended coastline near a polarimetric weather radar located near Darwin, northern ...
Sensitivity Analysis of Polarimetric Variables at a 5-cm Wavelength in Rain
Publisher: American Meteorological Society
Abstract: Sensitivity of 5-cm-wavelength polarimetric radar measurements to raindrop size and distribution is investigated. At this wavelength, resonance occurs for sizes larger than about 5 mm, and therefore several polarimetric ...
Polarimetric Radar Measurements of Tropical Rain at a 5-cm Wavelength
Publisher: American Meteorological Society
Abstract: A 5-cm wavelength (C band) polarimetric radar was deployed during the MCTEX (Maritime Continent Thunderstorm Experiment) field program. This paper investigates the use of the C-band data for quantitative rainfall measurements ...
Tropical Island Convection in the Absence of Significant Topography. Part II: Nowcasting Storm Evolution
Publisher: American Meteorological Society
Abstract: This paper examines influences on the short-range prediction of organized convection under conditions of strong diurnal forcing. The analyses are based on data provided by the Maritime Continent Thunderstorm Experiment, ...
