My co-author paper, "On the Sensitivity of Annual Streamflow to Air Temperature" is published in Water Resources Research and is now available on-line. This study was led by Dr. Cris Milly (USGS hydrologist). This study applies and tests a previously introduced "strong" extension of the Budyko hopotehsis and a "weak" extension to the 2,673 GRDC stations.
The key findings are included (from the abstract):
1) In application of the weak extension, the readily observed sensitivity of streamﬂow to precipitation contains crucial information about the sensitivity to potential evapotranspiration and, thence, to temperature.
2) Implementation of the strong extension is problematic, whereas the weak extension appears to capture essential controls of the temperature effect efﬁciently.
Two datasets (Kam et al. (2018) and Milly et al. (2018)) are generated for in this study and are available at the USGS ScienceBase-Catalog. The first data (Kam et al. 2018) is also available at the "Data" page of our research group website. We will update it yearly and upload the updated data in our "Data" page.
