Synthetic gravity waves

synthetic-gravity-waves DOI

This python package facilitates the creation of 2D synthetic atmospheric gravity-wave wave-packets mimicking the vertical velocity structure seen in numerical weather prediction models at fixed height or pressure levels.

Installation and usage

Install the package with pip from pypi.org

bash python -m pip install synthetic_gravity_waves

And the import synthetic_gravity_waves and use it to create a uniformly gridded vertical velocity field with synthetic gravity wave wave-packets:

```python import syntheticgravitywaves as sgw

phi = sgw.makesyntheticgravitywavecomposite(N=512, r_sigma=10.0, r0=80.0, lw0=10.0)

w0 = 5.0 # max characteristc vertical velocity [m/s] w = phi * w0

w now contains synthetic gravity wave packets with amplitude between -w0 and w0

```

Method

The method uses a point-sampling method based on the Poisson-disc sampling algorithm by Robert Bridson, but modified to in place of using a 2D density field to define the local density of points the spatial separation between points is sampled from a Gaussian distribution with mean r0 and standard deviation r_sigma. The sampling is done on a grid of shape (N, N). At the sampled points 2D Gaussians envelopes modulating plane-parallel carrier waves with a controllable characterisc wavelength.

See notebooks/usage.ipynb for details.
