Variation in large-scale climate phenomena
such as the El Nino-Southern Oscillation
(ENSO) can provide valuable predictive
information for regional climate and
hydrologic conditions in many parts of the
world.

Incorporating Large-scale Climate Information in Seasonal Streamflow
Forecasts
Specific objectives of this work include:
• Identify significant relationships
between large-scale climate datasets
including Sea Surface Temperatures
(SSTs), 500mb Geopotential Heights, and
Sea Level Pressures with streamflow,
precipitation, and urban demand.
• Evaluate the use of indices of
large-scale climate datasets to improve
probabilistic streamflow forecasts.
• Assess the improvement in forecasting
future streamflow extractions using
streamflow forecasts based on climate
information.
Results have shown that tropical SSTs in
the Nino3 and Nino3.4 regions can be
used to forecast winter streamflow up to
6-9 months in advance. These SST
indices, as well as time series derived from
Singular Value Decomposition (SVD)
analysis, have been incorporated into
probability of exceedance streamflow
forecast models.
