What is WRF used for?

The Weather Research and Forecasting (WRF) model /ˈwɔːrf/ is a numerical weather prediction (NWP) system designed to serve both atmospheric research and operational forecasting needs. NWP refers to the simulation and prediction of the atmosphere with a computer model, and WRF is a set of software for this.

What does WRF model stand for?

Weather Research and Forecasting
The Weather Research and Forecasting (WRF) Model is a next-generation mesoscale numerical weather prediction system designed to serve both atmospheric research and operational forecasting needs.

What is WRF data?

WRF is a state-of-the-art atmospheric modeling system designed for both meteorological research and numerical weather prediction. The data file output is from the WRF V3.

Is WRF hydrostatic?

The Weather Research and Forecasting (WRF) Model WRF is a numerical weather prediction system designed to serve both atmospheric research and operational weather predication needs. The WRF modeling system has Euclerian mass dynamic cores with terrain-following hydrostatic-pressure vertical coordinates.

Who uses WRF?

WRF is currently in operational use at NCEP and other national meteorological centers as well as in real-time forecasting configurations at laboratories, universities, and companies.

Is WRF model free?

WRF Portal and WRF Domain Wizard are free.

How do I run a WRF model?

Type nohup wrf.exe > wrf. out & to run WRF. The namelist is set up to run a 54h simulation. For a shorter run, change run_hours in the namelist….(3) Get and install WRF model code

  1. Untar the WRF code, and rename the directory it creates from WRFV2 to WRFV212.
  2. Type ./configure.
  3. Type ./compile em_real.

What is WRF NMM?

WRF-NMM is designed to be a flexible, state-of-the-art atmospheric simulation system that is portable and efficient on available parallel computing platforms. WRF-NMM is suitable for use in a broad range of applications across scales ranging from meters to thousands of kilometers, including: Real-time NWP.

How can I learn WRF model?

Running the WRF model is very easy: just find a good computer, follow the tutorials, compile and run. The real challenge is creating meaningful numerical experiments and critically evaluating the model output.

What is WRF WPS?

1 http://www2.mmm.ucar.edu/wrf/users/ The WRF Pre-Processing System (WPS) is a collection of Fortran and C programs that provides data used as input to the real.exe and real_nmm.exe programs. Both the ARW and NMM dynamical cores in WRF are supported by WPS.

How do you make a WRF?

WRF Build

  1. STEP ONE-A – GCC.
  2. STEP ONE-B – Setting Up Environment Variables.
  3. STEP TWO – Build NETCDF libraries for C and Fortran.
  4. STEP THREE – Get WRF Source Code.
  5. STEP FOUR – Get Chem/KPP WRF Source Code.
  6. STEP FIVE – Prepare the KPP code for compilation.
  7. STEP SIX – Prepare for Parallel code for compilation.

How long does it take to compile WRF?

Compile WRF-NMM for HWRF It takes about 30 minutes for the WRF-NMM compilation to complete. Note: If the compilation is sucessful, the two executables, real_nmm.exe and wrf.exe, will be created in the WRFV3/main/ directory.
