Short Summary

This study uses thermodynamic global warming simulations to quantify projected changes in local hydroclimate characteristics across the contiguous United States as a function of degree of global warming. The results highlight significant changes in temperature, precipitation, and soil moisture.

Objective

• Investigate the relationship between degree of global warming (DGW) and local hydroclimate characteristics using thermodynamic global warming simulations.

Study Configuration

• Spatial Scale: Regional domain over the contiguous United States.
• Temporal Scale: Long-term projections based on historical boundary conditions adjusted for warmer temperatures.

Methodology and Data

• Models used: Thermodynamic global warming (TGW) simulations with eight runs.
• Data sources: Historical climate data, adjusted for warmer temperatures.

Main Results

• Projected changes in local temperature range from 0.5 to 1.5°C per degree of global warming.
• Changes in precipitation and precipitation minus evapotranspiration range from ±60 mm yr−1 and ±40 mm yr−1, respectively.
• Soil moisture decreases by approximately 10 mm per degree Celsius of global warming.

Contributions

• This study provides a more detailed understanding of the relationship between DGW and local hydroclimate characteristics using TGW simulations with eight runs.
• The results highlight the importance of considering regional climate change projections in water resource management and planning.
