RISSensitivity of Typhoon Track Predictions in a Regional Prediction System to Initial and Lateral Boundary Conditions
Publisher: American Meteorological Society
Abstract: Tropical cyclone (TC) track predictions from the operational regional nonhydrostatic TC forecast system of the Taiwanese Central Weather Bureau (CWB) are examined for their sensitivities to initial and lateral boundary ...
Parallelization Strategies for the GPS Radio Occultation Data Assimilation with a Nonlocal Operator in the Weather Research and Forecasting Model
Publisher: American Meteorological Society
Abstract: he nonlocal excess phase observation operator for assimilating the global positioning system (GPS) radio occultation (RO) sounding data has been proven by some research papers to produce significantly better analyses for ...

Ensemble Typhoon Quantitative Precipitation Forecasts Model in Taiwan
Publisher: American Meteorological Society
Abstract: n this study, an ensemble typhoon quantitative precipitation forecast (ETQPF) model was developed to provide typhoon rainfall forecasts for Taiwan. The ETQPF rainfall forecast is obtained by averaging the pick-out cases, ...
An Impact Study of GPS Radio Occultation Observations on Frontal Rainfall Prediction with a Local Bending Angle Operator
Publisher: American Meteorological Society
Abstract: he impact of global positioning system (GPS) radio occultation (RO) soundings on the prediction of severe mei-yu frontal rainfall near Taiwan in June 2012 was investigated in this study using a developed local bending angle ...
A Quality Control Procedure Based on Bending Angle Measurement Uncertainty for Radio Occultation Data Assimilation in the Tropical Lower Troposphere
Publisher: American Meteorological Society
Abstract: AbstractThe fluctuation of radio occultation (RO) signals in the presence of refractivity irregularities in the moist lower troposphere results in uncertainties of retrieved bending angle and refractivity profiles. In this ...
A Vortex Relocation Scheme for Tropical Cyclone Initialization in Advanced Research WRF
Publisher: American Meteorological Society
Abstract: This paper introduces a relocation scheme for tropical cyclone (TC) initialization in the Advanced Research Weather Research and Forecasting (ARW-WRF) model and demonstrates its application to 70 forecasts of Typhoons ...
