Visualizing Typhoon Tracking: Upgrading Operations with SkyAviators
In addition to the JMA track forecasts, SkyAviators integrates predictions from WNI models and the Joint Typhoon Warning Center (JTWC). This side-by-side comparison highlights model differences and uncertainties, making it easier to assess the situation as a storm approaches.
The platform also includes satellite and radar overlays, plus automated airport alerts based on custom thresholds. Combined with detailed PDF briefings from our meteorologists, SkyAviators gives dispatch and operations teams the tools they need to evaluate risks and make informed decisions.
