Hierarchical clustering summary plots showing model drought evaluation statistics based on future (2056-95) drought characteristics derived from climate models downscaled by the MACA method assuming historical-standard stomatal resistance

Published by U.S. Geological Survey | Department of the Interior | Metadata Last Checked: July 16, 2025 | Last Modified: 20240716
The South Florida Water Management District (SFWMD) and the U.S. Geological Survey (USGS) have evaluated projections of future droughts for south Florida based on climate model output from the Multivariate Adaptive Constructed Analogs (MACA) downscaled climate dataset from the Coupled Model Intercomparison Project Phase 5 (CMIP5). The MACA dataset includes both Representative Concentration Pathways 4.5 and 8.5 (RCP4.5 and RCP8.5). A Portable Document Format (PDF) file is provided which presents hierarchical clustering summary plots showing model drought evaluation statistics based on future (2056-95) drought characteristics derived from climate models downscaled by the MACA method assuming historical-standard stomatal resistance for the period 1950-2095. Hierarchical clustering results and drought evaluation statistics based on 6-mo. and 12-mo. averaged balance anomaly timeseries for four regions are provided: (1) the entire South Florida Water Management District (SFWMD), (2) the Lower West Coast (LWC) water supply region, (3) the Lower East Coast (LEC) water supply region, and (4) the Okeechobee plus (OKEE+) water supply meta-region consisting of Lake Okeechobee (OKEE), the Lower Kissimmee (LKISS), Upper Kissimmee (UKISS), and Upper East Coast (UEC) water supply regions in the SFWMD.
