RISThe Use of Infrared Satellite Cloud Imagery Data as Proxy Data for Moisture and Diabatic Heating in Data Assimilation
Publisher: American Meteorological Society
Abstract: Geostationary and polar-orbiting satellites can provide useful proxy sources of moisture data and diabatic heating. It is shown that the use of this information during data assimilation leads to improved precipitation in ...
Numerical Simulation of the Development of AMEX Tropical Cyclone Irma
Publisher: American Meteorological Society
Abstract: High resolution observational data from the Australian Monsoon Experiment have been used to verify simulations of the development of tropical cyclone Irma. From a small amplitude, prehurricane cloud cluster, the FSU high ...
Tropical Prediction Using Dynamical Nudging, Satellite-defined Convective Heat Sources, and a Cyclone Bogus
Publisher: American Meteorological Society
Abstract: Some notable problems in tropical prediction have been (i) the sensitivity to, and inaccuracies in, the four-dimensional structure of parameterized convective heating, (ii) the inability of conventional data networks to ...
Secondary Eyewall Formation and Eyewall Replacement Cycles in a Simulated Hurricane: Effect of the Net Radial Force in the Hurricane Boundary Layer
Publisher: American Meteorological Society
Abstract: ultiple secondary eyewall formations (SEFs) and eyewall replacement cycles (ERCs) are simulated with the fifth-generation Pennsylvania State University (PSU)?National Center for Atmospheric Research (NCAR) Mesoscale Model ...
The BMRC High-Resolution Tropical Cyclone Prediction System: TC-LAPS
Publisher: American Meteorological Society
Abstract: A new Tropical Cyclone Limited Area Prediction System has been developed at the Australian Bureau of Meteorology Research Centre. The features of the new prediction system can be summarized as follows: first, a 12-h, ...
Characteristics of Tropical Cyclones in the Australian Region
Publisher: American Meteorological Society
Abstract: Characteristics of 500 tropical cyclones (TCs) in the Australian region and its three individual basins are examined based on 40 yr of satellite-supported observations. While tropical cyclones exhibit highly individual ...
Downstream Development in the Southern Hemisphere Monsoon during FGGE/WMONEX
Publisher: American Meteorological Society
Abstract: Evidence is presented of a downstream development mechanism operating across the entire longitudinal span of the 1978/79 Southern Hemisphere monsoon. Observationally it is seen as progressive cyclonic and anticyclonic ...
A High-Resolution Prediction Study of Two Typhoons at Landfall
Publisher: American Meteorological Society
Abstract: The landfall on the China coast of two typhoons has been studied using both observational diagnostics and a 30-km, 19-level prediction system. The typhoons vary in size and in the amount of rainfall they produced after ...
Australian Summer Monsoon Onset during AMEX 1987
Publisher: American Meteorological Society
Abstract: Onset of the Australian summer monsoon during 1986/87 is examined using the gridded tropospheric winds and surface pressure data from the Australian Bureau of Meteorology Tropical Region Analyses. Dramatic and sudden ...
Tropical Cyclone Contribution to Rainfall over Australia
Publisher: American Meteorological Society
Abstract: ropical cyclone (TC) rainfall over the Australian continent is studied using observations from 41 TC seasons 1969/70 to 2009/10. A total of 318 storms, whose centers either crossed the coastline or were located within ...
