Tropical cyclone tracking
Will code or pseudocode be added for the tropical cyclone tracking algorithm given in the paper? If not, would the authors mind sharing how thickness and relative vorticity can be computed from the output maps, and how radius can be checked?
Hi, the thickness and vorticity can be calculated by calling the Python library metpy
. You can refer to the calc
and units
parts in metpy
.
For radius, you can import distance
from the geopy
library which allows you to compute the distance between two positions in the Earth's surface. When a radius R (445km or 278km in the paper) is set, you can manually check all positions with a distance smaller than R.
So the algorithm is not going to be public?
