Polar vortex edge detection using Nash criteria

Project description

About

The module pyvortex consists of functions to calculate the equivalent latitude and edge of a polar vortex using Nash criteria.

Installation

pip install pyvortex

Usage

pyvortex is easy to use. Just import:

import pyvortex as vr

Northern Hemisphere

Instantiate the PolarVortex class using:

pol = PolarVortex(pv, uwind)

Get equivalent lqtitude for the provided vorticity data as:

eql = pol.get_eql()

If you want to get both equivalent latitude and Vortex edge, just use:

eql = pol.get_edge(min_eql=30)

Southern Hemisphere

Multiply pv and uwind by -1, and all other things will be the same.

Example:
