further than a dashboard

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, 1945–present
  • Wind circle radius (level 7/10/12) from 2001 on — when JTWC's quadrant reporting began
  • 2,086 named storms, ~162,000 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
  • My own model, Trackformer 1.2 (model card), overlaid on both live storms and past ones (Trackformer 1.1 where 1.2 has no run)
  • 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. In either mode you can overlay Trackformer 1.2, my own tropical-cyclone model: it carries the storm’s core through a learned western-Pacific pressure field started from analyses valid at or before the issue time — never a forecast field and never an official agency track — and forecasts the track and central pressure out to +120 h, with an experimental maximum-wind estimate. Where 1.2 has no run, the overlay falls back to Trackformer 1.1 and says so. Experimental research output, not an operational forecast.
