RISPredicting Hurricane Intensity and Associated Hazards: A Five-Year Real-Time Forecast Experiment with Assimilation of Airborne Doppler Radar Observations
Publisher: American Meteorological Society
Abstract: erformance in the prediction of hurricane intensity and associated hazards has been evaluated for a newly developed convection-permitting forecast system that uses ensemble data assimilation techniques to ingest high-resolution ...
Assimilating Airborne Doppler Radar Observations with an Ensemble Kalman Filter for Convection-Permitting Hurricane Initialization and Prediction: Katrina (2005)
Publisher: American Meteorological Society
Abstract: hrough a Weather Research and Forecasting model (WRF)-based ensemble Kalman filter (EnKF) data assimilation system, the impact of assimilating airborne radar observations for the convection-permitting analysis and prediction ...
Modification and Validation of Priestley–Taylor Model for Estimating Cotton Evapotranspiration under Plastic Mulch Condition
Publisher: American Meteorological Society
Abstract: ompared with more comprehensive physical algorithms such as the Penman?Monteith model, the Priestley?Taylor model is widely used in estimating evapotranspiration for its robust ability to capture evapotranspiration and ...
Active Disturbance Rejection Control for Hypersonic Flutter Suppression Based on Parametric ROM
Publisher: ASCE
Abstract: This paper presents an active disturbance rejection control algorithm (ADRC) to suppress the hypersonic flutter of a three-degrees-of-freedom (3-DOF) two-dimensional (2D) airfoil operating in multiparameters space. In this ...
Vertical 2D Nonhydrostatic Model Using Mode Splitting for Dam-Break Flows
Publisher: American Society of Civil Engineers
Abstract: A vertical two-dimensional (2D) nonhydrostatic numerical model for dam-break flows is proposed. This model combines a depth-averaged shallow-water equations (SWEs) model and a nonhydrostatic core using mode splitting. The ...
Tracking Gravity Waves in Baroclinic Jet-Front Systems
Publisher: American Meteorological Society
Abstract: Using a two-dimensional Fourier decomposition and a four-dimensional ray-tracing technique, the propagating characteristics and source mechanisms of mesoscale gravity waves simulated in idealized baroclinic jet-front systems ...
Evaluating the Impact of Crushing Process on Strength Characteristics and Leachability of Cement-Stabilized Dredged Sediment
Publisher: American Society of Civil Engineers
Abstract: Stabilization of dredged sediment and reusing the mixture as a construction material is an effective way to reduce environmental problems and save natural resources. However, the crushing process that occurs during ...
Finite Element Analysis Model and Residual Stress Optimization in Rotor Welding Process
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, the finite element method (FEM) is conducted for thermal and mechanical analysis of a half 2D axisymmetric welded rotor model. The temperature results after welding are obtained and supported by the experiment ...
Fast Warning Method for Rigid Hangers in a High-Speed Railway Arch Bridge Using Long-Term Monitoring Data
Publisher: American Society of Civil Engineers
Abstract: Excessive vibration of arch bridge hangers is a potential threat to the driving safety of high-speed trains; therefore, it is important to study the vibration characteristics and fast warning method of the hanger under ...
Verification of a High-Resolution Model Forecast Using Airborne Doppler Radar Analysis during the Rapid Intensification of Hurricane Guillermo
Publisher: American Meteorological Society
Abstract: The NOAA Hurricane Research Division (HRD) P-3 aircraft provided airborne radar observations during the period of rapid intensification of Hurricane Guillermo on 2 August 1997. The inner core structure and evolution of ...
