Distributed Quantitative Precipitation Forecasting Using Information from Radar and Numerical Weather Prediction Models
The benefits of short-term (1–6 h), distributed quantitative precipitation forecasts (DQPFs) are well known. However, this area is acknowledged to be one of the most challenging in hydrometeorology. Previous studies suggest that the ‘‘state of the art’’ methods can be enhanced by exploiting relevant information from radar and numerical weather prediction (NWP) models, using process physics and ...
متن کاملNumerical Weather Prediction Models
JMA operates NWP models to meet various kinds of requirements on weather forecasting. The suite of the NWP models covers a wide temporal range of forecast periods from a few hours to two seasons providing a seamless sequence of products for the public. The Global Spectral Model (GSM) produces 84-hour forecast four times a day (00, 06, 12, 18 UTC) to support the official short-range forecasting ...

متن کاملComparison of weather radar, numerical weather prediction and gauge-based rainfall estimates
Hydrological hazards have been extensive world-wide in recent times. In particular, there has been widespread flooding across much of Australia in response to extreme precipitation events. Hydrological modelling can be used to effectively manage the extensive effects of flood events, but the primary input for hydrological hind-, nowand fore-casting of these events is reliable knowledge of both ...
متن کاملValidating Precipitation Estimates Simulated by the Numerical Weather Forecast Models Eta and Mm5 for Use in Flood Forecasting
Accurate rainfall forecasts using numerical weather prediction (NWP) models can provide significant increases in forecast lead-time and thereby give greater opportunity for flood warning and protection measures. One goal of the FLOODRELIEF project is to quantify the uncertainty of forecast precipitation fields from two different NWP models (Eta and MM5) to investigate the impact of precipitatio...
