Flood hazard across the western United States (US) has generally shown decreasing trends in recent decades. This region's extreme streamflow is highly influenced by natural variability, which could either mask or amplify anthropogenic trends. In this study, we utilize a technique known as dynamical adjustment to assess historical (1970–2020) annual maximum 1-day (Qx1d) from unregulated basins U...

This paper examines further one suggested hypothesis, that variations in solar radiation reaching the surface (Rs) have caused much of the observed decadal temperature variability. Because Rs only heats air during the da...
