Stony Brook University (Y. Lin) scheme . This is a 5-class scheme with riming intensity predicted to account for mixed-phase processes. The MAD-WRF model is designed to improve the cloud analysis and solar irradiance short-range forecast. Rename wrfinput_d02 and wrfbdy_d02 to wrfinput_d01 and wrfbdy_d01, respectively. Rename wrfinput_d02 and wrfbdy_d02 to wrfinput_d0 and wrfbdy_d01, respectively.

• Idealized cases are a means to simulate simple tests for a broad range of space and time scale.
• In addition to those listed above, domain-averaged rainfall, surface evaporation, and sensible and latent heat fluxes are output in stdout file.
• After hitting the return key, a ‘configure.wrf’ file is created.
• The second option allows the nest to move automatically, based on an automatic vortex-following algorithm .
• Other filter options that use variable eddy viscosity are not positive definite or monotonic.
• Activate UA Noah LSM changes to use a different snow-cover physics.

It is advised that either hydrostatic pressure or total pressure (PB + P) be used for diagnostics and for vertical interpolations. To use this option, add the following namelist settings. The first step is to create a text file (e.g., my_file_d0X.txt), for each domain, and define the name of that file in the &time_control section of namelist.input, as indicated below. See namelist options descriptions under the &stoch section.

The top layer is taken to be 1 cm thick, and the lower layer is 99 cm. Grid aggregate vegetation and soil parameters are derived from fractional coverage of land use categories and soil texture types. There are two indirect nudging schemes that correct biases in 2-m air temperature and moisture by dynamic adjustment of soil moisture and deep soil temperature . The prognostic variable for soil moisture is volumetric soil moisture content, minus the residual soil moisture tied to soil particles, and therefore not participating in moisture transport.

New mass-flux scheme with deep and shallow components and momentum transport. Column moist adjustment scheme relaxing towards a well-mixed profile . Adds to BEP, building energy budget with heating and cooling systems.

• The grid staggering is the Arakawa C-grid.
• It is okay to have the same field in multiple streams.
• Asks the model to write-out an empty file with the name ‘wrfoutReady_d_;Useful in production runs so that post-processing code can check on the completeness of this file.
• All should be positive definite, although we have not examined and tested all options for this property.
• Deactivates 2nd-order horizontal mixing for chem species.
• Set to 1 for feedback from nest to its parent domain.

The grid cell can be partially covered with snow, when snow water equivalent is below a threshold value of 3 cm. When this condition occurs, surface parameters, such as roughness length and albedo, are computed as a weighted average of snow-covered and snow-free areas. The energy budget utilizes an iterative snow melting algorithm.

3 Day Runs (eg, Previous Ncar Daily Real-time Runs Over The Us):

Digital filter initialization is a method to remove initial model imbalance as, for example, measured by the surface pressure tendency. This may be important when one is interested in the 0 – 6 hour simulation/forecast. It runs a digital filter during a short model integration, backward and forward, and then starts the forecast. In WRF implementation, this is all done in a single job. DFI can be used for multiple domains with concurrent nesting, with feedback disabled.

The perturbation field is saved as rstoch in the history files. The perturbation field is saved asrand_pert in the history files. Note that this option does not work with “sf_ocean_physics” options. The purpose of this step is to ingest higher resolution terrestrial fields and corresponding land-water masked soil fields.

She is a first-generation Mexican-American, and the first to attend college and grad school. Negrete-García’s research focuses on the impacts of climate change on phytoplankton communities in the Arctic ocean. She has developed a model feature that represents biodiverse plankton communities that can be embedded in a global circulation model.

Works with same options as BEP. Any field that can be part of the optional IO must already be declared as a state variable in the Registry. Avoid using streams 1, 2, 6, and 23 as a new stream to output variables. It is not necessary to remove fields from one stream to add them to another. Since the scheme uses Fast Fourier Transforms provided in the library FFTPACK, we recommend the number of gridpoints in each direction to be a product of small primes. If the number of gridpoints is a large prime in at least one of the directions, the computational cost may increase substantially.

Not recommended to change default value. Frequency to update the stochastic perturbations .
