Table 1 Precipitation extreme indices used in this study.
No. | Extreme indices | Name | Definition | Units |
|---|---|---|---|---|
1 | CDD | Consecutive dry days | PRij is the daily precipitation amount on day i in period j. Count the largest number of consecutive days where PRij < 1 mm | days |
2 | RX5 day | Maximum consecutive 5-day precipitation | PRkj is the precipitation amount for the 5-day interval ending k, period j. Then maximum 5 d values for period j are: RX5dayj = max (PRkj) | mm |
3 | R20 mm | Very heavy precipitation days | PRij is the daily precipitation amount on day i in period j. Count the number of days where PRij > 20 mm | days |
