Climate Variability and Change in Mobile, Alabama

Appendix E.1. Temperature Variables by Station, Part 1 of 6

Appendix E of Main Report¹

Appendix E: Tables of Projected Changes in Temperature and Precipitation

Appendix E.1. Temperature Variables by Station

Appendix E.2. Precipitation Variables by Station

This appendix provides the climate model ensemble means for each variable analyzed. Each table also includes the variability within the climate model ensemble. For the A2 and B1 emission scenarios, which are derived from 10 climate models, the variability shown is one standard deviation above and below the ensemble mean. For the A1FI scenario, which is derived from 4 climate models, the variability shown is the maximum and minimum A1FI model projections.

The projections are based on the daily statistically downscaled data provided by Dr. Katharine Hayhoe and Dr. Anne Stoner. The downscaled data was then tailored to provide projections relevant to transportation planners and engineers to inform climate impact assessments (the methodology of how to tailor this data was developed through a collective effort that included contributions from FHWA, ICF, and PB). Dr. Katharine Hayhoe and Dr. Anne Stoner processed the daily downscaled data to produce the values shown in all tables herein except those related to 24-hour precipitation. Staff at ICF processed the 24-hour precipitation variables, shown in Table 112 through Table 125. Projected changes in 24-hour precipitation events calculated using an alternate method are available in Hayhoe and Stoner (2012).
