From: The trend and spatial spread of multisectoral climate extremes in CMIP6 models
S/N | Index | Description (unit) | Name | Sector |
|---|---|---|---|---|
1 | DTR | The mean difference between the daily maximum temperature and the daily minimum temperature (Celsius) | Daily Temperature Range | AF |
2 | DTRV | Mean absolute day-to-day variation in the daily temperature range (Celsius) | Daily Temperature Range Variability | AF |
3 | DSF | The number of dry periods of n days and more, during which the accumulated or maximal daily precipitation amount on a window of n days is under 1.0 mm (days) | Dry Spell Frequency | HW, AF |
4 | DSTL | Total number of days in dry periods of a minimum length, during which the maximum or accumulated precipitation within a window of the same length is under 1.0 mm (days) | Dry Spell Total Length | HW, AF |
5 | ETR | The maximum of maximum temperature (TXx) minus the minimum of minimum temperature (TNn) for the given time period (Celsius) | Extreme Temperature Range | AF |
6 | HWF | The number of heatwaves over a given period. A heatwave is defined as an event where the minimum and maximum daily temperature both exceeds specific thresholds over a minimum number of days, usually for > = 3 days (events) | Heat Wave Frequency | H, HW, AF |
7 | HWI | Number of days that are part of a heatwave, defined as five or more consecutive days over 27 °C (days) | Heat Wave Index | H, HW, AF |
8 | HWTL | The total length of heatwaves over a given period. A heatwave is defined as an event where the minimum and maximum daily temperature exceeds 22 °C and 30 °C (respectively) over a minimum number of days. This is the sum of all days in such events (days) | Heat Wave Total Length | H, HW, AF |
9 | HSF | The number of hot spells over a given period. A hot spell is defined as an event where the maximum daily temperature exceeds 30 °C over a minimum number of days, usually for > = 3 days (events) | Hot Spell Frequency | H, HW, AF |
10 | DPI | Average precipitation over wet days (mm/day) | Average Daily Precipitation Intensity | HW, AF |
11 | WDD | The total number of days where warm and dry conditions coincide (days) | Warm and Dry Days | H, HW, AF |
12 | WSDI | Number of days inside spells of a minimum number of consecutive days where the daily maximum temperature is above the 90th percentile (days) | Warm Spell Duration Index | H, HW, AF |
13 | HWML | The maximum length of heatwaves over a given period (days) | Heat Wave Maximum Length | H, HW, AF |
14 | MCCD | Maximum number of consecutive dry days within the period where precipitation is below 1 mm/day (days) | Maximum number of consecutive dry days | H, HW, AF |
