Simulation of rainfall temporal distribution pattern using WRF Model (case study of Parsian dam basin)
During the rainfall, the intensity of precipitation varies. Changes in the amount of precipitation during an event of rainfall are effective in the resulting of flood and its intensity. Knowledge of how rainfall changes over time during rainfall is determined by temporal distribution pattern of rainfall. For this purpose, availability of short-term time scales rainfalls data are important that ...
متن کاملThe impact of different WRF model physical parameterizations and their interactions on warm season MCS rainfall
In recent years, a mixed-physics ensemble approach has been investigated as a method to better predict mesoscale convective system (MCS) rainfall. For both mixed-physics ensemble design and interpretation, knowledge of the general impact of various physical schemes and their interactions on warm season MCS rainfall forecasts would be useful. Adopting the newly emerging Weather Research and Fore...
متن کاملP1.89 Comparison of Impacts of Wrf Dynamic Core, Physics Package, and Initial Conditions on Warm Season Rainfall Forecasts
A series of simulations were performed for 15 warm season convective system cases occurring during August 2002 using several different WRF (Weather Research and Forecasting) model configurations to compare the sensitivity of the rainfall forecasts to changes in dynamic core, physics package, and initial conditions. Most simulations used 8 km grid spacing, but a few 10 km simulations available f...
متن کاملDoes increased predicted warm-season rainfall indicate enhanced likelihood of rain occurrence?
The likelihood of simulated rainfall above a specified threshold being observed is evaluated as a function of the amounts predicted by two mesoscale models. Evaluations are performed for 20 warm-season mesoscale convective system events over the upper Midwest of the United States. Simulations were performed using 10-km versions of the National Centers for Environmental Prediction Eta Model and ...
متن کاملObject-Based Verification of Precipitation Forecasts. Part I: Methodology and Application to Mesoscale Rain Areas
A recently developed method of defining rain areas for the purpose of verifying precipitation produced by numerical weather prediction models is described. Precipitation objects are defined in both forecasts and observations based on a convolution (smoothing) and thresholding procedure. In an application of the new verification approach, the forecasts produced by the Weather Research and Foreca...
