RISEvaluations of BDA Scheme Using the Advanced Research WRF (ARW) Model
Publisher: American Meteorological Society
Abstract: A tropical cyclone bogus data assimilation (BDA) scheme is built in the Weather Research and Forecasting three-dimensional variational data assimilation system (WRF 3D-VAR). Experiments were conducted (21 experiments with ...
The Impact of Multisatellite Data on the Initialization and Simulation of Hurricane Lili’s (2002) Rapid Weakening Phase
Publisher: American Meteorological Society
Abstract: Numerical experiments have been conducted to examine the impact of multisatellite data on the initialization and forecast of the rapid weakening of Hurricane Lili (in 2002) from 0000 UTC to landfall in Louisiana on 1300 ...
Numerical Evaluation of Myofiber Orientation and Transmural Contractile Strength on Left Ventricular Function
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The left ventricle (LV) of the heart is composed of a complex organization of cardiac muscle fibers, which contract to generate force and pump blood into the body. It has been shown that both the orientation and contractile ...
Experiments of Hurricane Initialization with Airborne Doppler Radar Data for the Advanced Research Hurricane WRF (AHW) Model
Publisher: American Meteorological Society
Abstract: Initialization of the hurricane vortex in weather prediction models is vital to intensity forecasts out to at least 48 h. Airborne Doppler radar (ADR) data have sufficiently high horizontal and vertical resolution to resolve ...
Estimation of TAMDAR Observational Error and Assimilation Experiments
Publisher: American Meteorological Society
Abstract: ropospheric Airborne Meteorological Data Reporting (TAMDAR) observations are becoming a major data source for numerical weather prediction (NWP) because of the advantages of their high spatiotemporal resolution and humidity ...
Adjoint-Derived Observation Impact Using WRF in the Western North Pacific
Publisher: American Meteorological Society
Abstract: n increasing number of observations have contributed to the performance of numerical weather prediction systems. Accordingly, it is important to evaluate the impact of these observations on forecast accuracy. While the ...
Improving Lake-Breeze Simulation with WRF Nested LES and Lake Model over a Large Shallow Lake
Publisher: American Meteorological Society
Abstract: AbstractThe Weather Research and Forecasting (WRF) Model is used in large-eddy simulation (LES) mode to investigate a lake-breeze case occurring on 12 June 2012 over the Lake Taihu region of China. Observational data from ...
Differential Effects of Isoproterenol on Regional Myocardial Mechanics in Rat Using Three-Dimensional Cine DENSE Cardiovascular Magnetic Resonance
Publisher: American Society of Mechanical Engineers (ASME)
Abstract: The present study assessed the acute effects of isoproterenol on left ventricular (LV) mechanics in healthy rats with the hypothesis that β-adrenergic stimulation influences the mechanics of different myocardial regions ...
Application of an Adiabatic WRF Adjoint to the Investigation of the May 2004 McMurdo, Antarctica, Severe Wind Event
Publisher: American Meteorological Society
Abstract: The tangent linear and adjoint of an adiabatic version of the Weather Research and Forecasting (WRF) Model with its Advanced Research WRF (ARW) dynamic core have been developed. The source-to-source automatic differentiation ...
The Weather Research and Forecasting Model's Community Variational/Ensemble Data Assimilation System: WRFDA
Publisher: American Meteorological Society
Abstract: milation is the process by which observations are combined with short-range NWP model output to produce an analysis of the state of the atmosphere at a specified time. Since its inception in the late 1990s, the multiagency ...
