How to compute and visualize the Standardized Precipitation Index (SPI) for drought analysis

The Standardized Precipitation Index (SPI) quantifies how precipitation deviates from the historical average over multiple time scales (e.g., from 1 to 12 months), allowing for consistent monitoring of droughts and floods across regions and time, making it a valuable tool for early warning and risk assessment systems.
