Heat Wave Probability

Heat wave duration hazard refers to the length of days where the daily maximum temperature is more than 5℃ from a centered six day average. The hazard has 3 severity levels (Low, Moderate, High). Low heat wave hazard intensity corresponds to 5 and 6 days, moderate to 7 and 8 days, while high to more than 9 days. For each of the severity levels, heat wave duration hazard is calculated for each of the 12 calendar months. The returned values of the heat wave duration hazard are probabilities of exceeding the above duration thresholds per severity class per calendar month.
