Prompt Description

APPROVED. Conceptual diagram outline for flash drought event (FDE) detection using standardized evaporative stress ratio (SESR) and its change (ΔSESR). The figure title should be placed at the top in a small font. The conceptual workflow for FDE detection is as follows: Panel 1 (Inputs): Box label: ET & PET (daily). Subtext: → ESR = ET / PET → pentads (5-day). Icon idea: thermometer + droplet or ET arrows. Panel 2 (Standardization): Box label: SESR (pentad). Subtext: Seasonal standardization (pentad-of-year). Panel 3 (Intensification): Box label: ΔSESR. Subtext: Pentad-to-pentad change (standardized). Panel 4 (Thresholds): Box label: Seasonal thresholds. Subtext: P40 P25 P20. Panel 5 (Decision): Diamond.
