The Heat Wave Magnitude Index (HWMId) takes into account both heatwave duration and intensity. HWMId is defined as the maximum magnitude of the heawaves occurring in a year, where a heatwave is defined as the periods of at least three consecutive days with maximum temperature above the calendar 90th percentile centered on a 31 day reference period. Heatwave magnitudes are grouped into seven categories, ranging from normal (greater than 1) to ultra extreme (greater than 32). ≤1 Normal <2≤ Moderate <3≤ Severe <4≤ Extreme <8≤ Very Extreme <16≤ Super Extreme <32≤ Ultra Extreme.
