Typhoon Tracks

Every named Western Pacific typhoon since 1985 — pick one and see its path, its intensity over its lifetime, and (from 2001 on) the actual reported size of its wind field.

Path, strength, and now — radius

My typhoon-data-analysis project is a Dash app for exploring West Pacific typhoon tracks, clustering, and ENSO relationships. This takes the same IBTrACS foundation further for the web: instead of just a path and a category, it plots the storm's actual reported wind radius — how far out Beaufort-level 7, 10, and 12 winds extended — on a Pacific-focused, zoomable map, scrubbing smoothly through the storm's life by real elapsed time rather than by raw observation.

Data & scope
  • IBTrACS v04r01 (NOAA NCEI), Western Pacific basin, 1985–present
  • Wind circle radius (level 7/10/12) from 2001 on — when JTWC's quadrant reporting began
  • 1,076 named storms, ~85,000 track observations
  • Chinese storm names from Taiwan CWA's own typhoon database
  • Two intensity standards: Saffir-Simpson-style and Taiwan (CWA)
  • Derived live: Dvorak T-number, ACE, rapid intensification
  • Forecast mode: JMA's live official 5-day forecast for any active typhoon
  • Season climatology tagged with real NOAA ENSO (ONI) values

Track & forecast explorer

In Track mode, choose a season and a typhoon, then scrub through its path or hit play — wind, pressure, Dvorak number, and wind-circle radii update live on the right; flip to a whole-season view to see every track at once. Switch to Forecast to pull the Japan Meteorological Agency's official, live 5-day forecast for any typhoon active right now — the real forecast track and its growing probability circles, fetched straight from JMA in your browser.
