Variability And Potential Sources Of Predictability Of North American Runoff, Edwin P. Maurer, Dennis P. Lettenmaier, Nathan J. Mantua Sep 2004

Variability And Potential Sources Of Predictability Of North American Runoff, Edwin P. Maurer, Dennis P. Lettenmaier, Nathan J. Mantua

Civil, Environmental and Sustainable Engineering

Understanding the space-time variability of runoff has important implications for climate because of the linkage of runoff and evapotranspiration and is a practical concern as well for the prediction of drought and floods. In contrast to many studies investigating the space-time variability of precipitation and temperature, there has been relatively little work evaluating climate teleconnections of runoff, in part because of the absence of data sets that lend themselves to commonly used techniques in climate analysis like principal components analysis. We examine the space-time variability of runoff over North America using a 50-year retrospective spatially distributed data set of runoff …

The magnitude of future climate change depends substantially on the greenhouse gas emission pathways we choose. Here we explore the implications of the highest and lowest Intergovernmental Panel on Climate Change emissions pathways for climate change and associated impacts in California. Based on climate projections from two state-of-the-art climate models with low and medium sensitivity (Parallel Climate Model and Hadley Centre Climate Model, version 3, respectively), we find that annual temperature increases nearly double from the lower B1 to the higher A1fi emissions scenario before 2100. Three of four simulations also show greater increases in summer temperatures as compared with …


Potential Effects Of Long-Lead Hydrologic Predictability On Missouri River Main-Stem Reservoirs, Edwin P. Maurer, Dennis P. Lettenmaier Jan 2004

Potential Effects Of Long-Lead Hydrologic Predictability On Missouri River Main-Stem Reservoirs, Edwin P. Maurer, Dennis P. Lettenmaier

Civil, Environmental and Sustainable Engineering

Understanding the links between remote conditions, such as tropical sea surface temperatures, and regional climate has the potential to improve streamflow predictions, with associated economic benefits for reservoir operation. Better definition of land surface moisture states (soil moisture and snow water storage) at the beginning of the forecast period provides an additional source of streamflow predictability. The value of long-lead predictive skill added by climate forecast information and land surface moisture states in the Missouri River basin is examined. Forecasted flows were generated that represent predictability achievable through knowledge of climate, snow, and soil moisture states. For the current main-stem …
