Description |
---|---|
Rainy days (dr) |
Total number of days in a year with rainfall over a threshold (default: 2.5 mm) |
Consecutive wet days (cwd) |
The maximum length of wet spell (maximum consecutive days in a year with precipitation ≥ a threshold (default: 2.5 mm)) |
Heavy precipitation days (d64) |
The number of days in a year with precipitation ≥ a threshold (default: 64 mm) |
Total precipitation in wet days (rtwd) |
The sum of precipitation in all the rainy days of a year |
Maximum daily rainfall (rxa) |
The maximum daily rainfall in a year |
Maximum 5-days rainfall (rx5d) |
The highest magnitude of rainfall accumulations for consecutive 5 days in a year |
Simple daily intensity index (sdii) |
It represents the average intensity of a rainy day over a year (computed as the ratio of rtwd and dr) |
Precipitation concentration index (pci) |
An indicator for temporal precipitation distribution (represents how uniformly annual precipitation is istributed in the months) |
Coolest night (mnadt) |
Minimum value of temperature over a year (the least daily TMIN value of a year) |
Hottest day (mxadt) |
Maximum value of temperature over a year (the highest daily TMAX value of a year) |
Diurnal Temperature Range (dtr) |
The difference between the maximum and minimum temperature of a year (i.e., the difference between mxadt and mnadt) |
Modified Mann-Kendall test statistic (mmk_hr) |
The trend detecting statistic of the non-parametric MMK test advocated by Hamed and Rao (1998) |
Spearman’s Rho statistics (spr) |
The trend detecting statistic of the non-parametric Spearman’s Rho test |
Sen’s slope estimate (sse) |
The trend detecting statistic (i.e., slope) of Sen’s slope |
Magnitude of trend (sstr) |
The ratio of product of Sen’s slope (sse) with number of data points to the mean value (expressed in terms of percentage) |
