- I'm writing code to display wind swath over life of storm using track & wind radii. Want to include exact smoothing NHC uses. "smooth wind field depicted on the graphic is produced by a trigonometric interpolation between the four defined radii" (www.nhc.noaa.gov/aboutwindfie...) Anyone know how?Aug 30, 2025 17:49
- Using actual wind radii gives results that do not match NHC due to smoothing not being applied. 1st image is NHC smoothed wind swath. 2nd is wind radii based on forecast advisory history (with interpolation; has bugs) 3rd is a smoothed wind field based on equation from AI. But I want exact NHC code.
