Raining Bell

Raining Bell integrates nationwide radar observations with FORMOSAT‑7 satellite data, applying data‑assimilation and radar‑echo extrapolation to deliver up to three hours of localized rainfall trend forecasts. Designed by NCDR and developed with NCHC and ThinkYes Technology under NSTC guidance, the extension combines real‑time CWA forecasts with its own observations to provide intelligent, human‑centered early warnings for meteorological disasters.

The latest release adds the Firefly smart voice assistant powered by the TAIDE LLM, enabling natural interactions in Mandarin or Taiwanese. Location‑based services, push notifications, and proactive alerts ensure timely, personalized weather information. Note: this product is experimental research; for official forecasts, refer to Central Weather Administration announcements.
