RISSome Aspects of Vortex Structure Related to Tropical Cyclone Motion
Publisher: American Meteorological Society
Abstract: Some effect of tropical cyclone structure on the vortex motion are examined in a nondivergent, barotropic numerical model with no basic current. As suggested earlier by DeMaria, the initial maximum wind speed has little ...
A Comprehensive Test of the Navy Nested Tropical Cyclone Model
Publisher: American Meteorological Society
Abstract: The tropical cyclone forecasting skill level of the Joint Typhoon Warning Center (JTWC) has reached a plateau and has shown little or no lasting improvement during the last 10 years. Because JTWC relies on an array of ...
Development and Testing of Statistical Tropical Cyclone Forecasting Techniques for the Southern Hemisphere
Publisher: American Meteorological Society
Abstract: The Fleet Numerical Oceanography Center (FNOC) Numerical Variational Analysis (NVA) has been used to develop statistical?synoptic tropical cyclone forecast schemes for the Southern Hemisphere. Results, from a limited sample, ...
Contributions to Tropical Cyclone Motion by Small, Medium and Large Scales in the Initial Vortex
Publisher: American Meteorological Society
Abstract: A two-dimensional Fourier decomposition procedure is used to isolate small (≤500 km), medium (500< ? ≤ 1500 km) and large (>1500 km) scale components of some typical tangential wind profiles used in theoretical studies of ...
Incorporating Surface-Winds and Rainfall Rates into the Initialization of a Mesoscale Hurricane Model
Publisher: American Meteorological Society
Abstract: The initialization of a three-dimensional model with operational data for Hurricane Eloise (1975) was studied to assess the impact of using bogus storm data, surface winds, rainfall rates, and a high-resolution surface ...
A Comparison of Total Precipitable Water between Reanalyses and NVAP
Publisher: American Meteorological Society
Abstract: This study compares monthly total precipitable water (TPW) from the National Aeronautics and Space Administration (NASA) Water Vapor Project (NVAP) and reanalyses of the National Centers for Environmental Prediction (NCEP) ...
A Comparison of the Performance of Two Operational Dynamic Tropical Cyclone Models
Publisher: American Meteorological Society
Abstract: This paper compares the performance of two multi-level high-resolution baroclinic tropical cyclone models which are currently in operational use. In the Atlantic, the National Hurricane Center utilizes the Movable Fine-mesh ...
Extreme Rapid Intensification of Typhoon Vicente (2012) in the South China Sea
Publisher: American Meteorological Society
Abstract: ne of the primary challenges for both tropical cyclone (TC) research and forecasting is the problem of intensity change. Accurately forecasting TC rapid intensification (RI) is particularly important to interests along ...
Predictions of 2010’s Tropical Cyclones Using the GFS and Ensemble-Based Data Assimilation Methods
Publisher: American Meteorological Society
Abstract: xperimental ensemble predictions of tropical cyclone (TC) tracks from the ensemble Kalman filter (EnKF) using the Global Forecast System (GFS) model were recently validated for the 2009 Northern Hemisphere hurricane season ...
Multimodel Superensemble Forecasting of Tropical Cyclones in the Pacific
Publisher: American Meteorological Society
Abstract: Using currently available operational forecast datasets on the tracks and intensities of tropical cyclones over the Pacific Ocean for the years 1998, 1999, and 2000 a multimodel superensemble has been constructed following ...
