Description
Anomalies can help identify variability more meaningfully than absolute values. High or low absolute values in one location may be ‘normal’ for that location while they may be catastrophic in another. The Extreme Wind - Anomaly dataset provides more meaningful local comparisons by capturing where extreme wind is unusual for a specific location.
Technical Description
The Extreme Wind, Anomaly - Monthly Summary (Global, v1.0) dataset provides a global summary of
exposure to anomalous extreme wind events, derived from ERA5-Land Daily Aggregated and Timely reanalysis data. For
each month, daily max 1-hour wind speeds are evaluated against both a 21 mph wind speed threshold and the 95th
percentile baseline wind speed (1992-2021).
The dataset quantifies the frequency of days in which both conditions are exceeded, indicating anomalously extreme wind events. The resulting summaries are expressed as the proportion of days in the month meeting this criterion. Outputs have an 11 km spatial resolution and are published with a temporal granularity of one month. This product is intended to support risk assessments, climate adaptation planning, and monitoring of exposure to anomalous wind hazards.
