Variable General Info
Rainfall seasonality ?Comment:To assess shifts in seasonality for the Rio Santa basin for all water balance fluxes, the seasonality index of Walsh and Lawler (1981) modified to handle negative values (by offsetting by the minimum so that all negatives become positive) was calculated using WaterWorld for the baseline and for the climate change scenarios for comparison. An index value of greater than 0.4 is considered seasonal, >0.8 marked seasonal with a long dry season and >1.2 extreme seasonal with almost all water available in 1-2 months. |
