Variable Variable Description
HotSpot (°C)
HSMMM
Daily HotSpot in that grid cell, using MMM baseline
HSpeak Maximum HS value that year
Duration (day)
Dc
Duration of continuous positive HotSpot, based on the period that includes the maximum annual HotSpot
Dtot Total number of days with positive HotSpot
Dp Number of days between the first positive HotSpot and onset of a continuous positive HotSpot period (i.e., Dc), referring to the “conditioning or priming period”
Accumulated heat stress (°C·day) Ac Accumulated sum of heat stress during the continuous positive HotSpot period, based on the time period used for Dc
Atot Accumulated sum of all HotSpot that year
Heating rate (°C·day-1) HRc Rate of SST increase from the start of the Dc period to the date of HSpeak
