Events

WRSI Events surface discrete developments related to weather regime transitions, forecast uncertainty, and extreme temperature risk.

They complement the continuous view provided by WRSI Signals by highlighting specific moments where weather conditions shift or become unusually uncertain.

Available Events​

regime_shift()​

Forecast-instability regime transitions. Flags moments when the WRSI regime changes.

extreme_risk()​

Unusually high forecast uncertainty events. Triggered when model ensemble spread or forecast disagreement exceeds historical norms.

flip_risk_alert()​

Rapid directional reversals in model runs. Identifies periods where successive forecast updates change direction sharply, indicating unstable atmospheric patterns and heightened near-term uncertainty.

tail_risk_alert()​

Extreme temperature probability events. Flags periods where the forecast probability of extreme temperature outcomes (hot or cold) exceeds normal thresholds.

Typical use cases​

  • Monitoring forecast-instability regime transitions
  • Identifying periods of elevated forecast uncertainty
  • Tracking directional instability in weather model outputs
  • Monitoring forecast probability of extreme temperatures

WRSI Events provide discrete context around changes in weather regimes and forecast conditions.
