Precipitation Dependence of Temperature Trends Across the Contiguous US

Temperature and precipitation covary across timescales due to thermodynamic dynamic processes. We examine spatial patterns trends of daily dependence maximum minimum temperature anomalies the contiguous United States during 1950–2020. In warm season, temperatures are anomalously cool on wet days, while in days. During 1950–2020, warm-season increased 0.5°C more days than dry whereas warmed slightly both season. By contrast, climate models show subtle consistent with approximately 0.2°C warming Improved understanding precipitation-dependent is critical for modeling impacts changing snowpack, drought, heat stress.
