Because it uses linear segments (polygons) rather than complex high-degree polynomials, it’s computationally fast—essential when processing millions of data points from satellites and ground stations.
It can handle "non-linear" events (like a sudden thunderstorm) better than a simple average. Mathematics of the Weather: Polygonal Spline Lo...
