How to represnt weather polygons in a simulated aircraft flight path. I am writing a code for Aircraft flight path optimisation in adverse weather condition

I am trying to write a code for Aircraft flight path optimisation. I have a grid of 300-by-200, in which I represent two Airport locations and the normal flight path between them.

a. I want to represent adverse weather like turbulence in the flight path by polygons. b. Now the aircraft should identify these polygons as impenetrable object and decide on an alternate path by detouring from these polygons.

How do I show or represent the polygons as an impenetrable object in Matlab? I am not getting the idea how to do this project in Matlab.
