Introduction
At least three decadal climate
variability (DCV) phenomena -- the
Pacific Decadal Oscillation, the
tropical Atlantic sea-surface
temperature (SST) gradient
oscillation, and the west Pacific Warm
Pool SST variability -- significantly
impact the hydro-meteorology of the
Missouri River Basin.
From 2008-2010, the team assessed
the effects of these long-term sea
surface temperature phenomena on
water supplies and crop yields in the
Basin, along with the perceptions of
stakeholders about their DCV
information needs and the potential
applications of DCV outlooks in the
basinâs water and agriculture sectors.
Financial assistance for the study was
provided by the Sectoral Applications
Research Program, Climate Program
Office , U.S. Department of
Commerce, National Oceanic and
Atmospheric Administration.

Gathering input from 90 representatives from agriculture, water and electric power utility,
transportation, natural resources and government sectors
Modeling Results:
Association of positive and negative phases of DCV phenomena with
streamflow in three sub-basins in the northern Missouri River Basin.
EPIC simulation of DCV impact
on spring wheat yields in the MRB
HUMUS-SWAT simulation of DCV
impact on water yield in the basin
Potential Applications of DCV Outlooks:
Agriculture: Guidance for future crop selection and cattle stocking rates,
appropriate land-use, irrigation development, pesticide and fertilizer
applications, and insurance coverage
Municipal water: Guidance for water infrastructure investments, water
uses and pricing, land use planning, and flood protection
River Management: Guidance for reservoir operations, barge
transportation viability, recreation and fisheries management
Energy (hydropower, coal, and nuclear): Guidance for infrastructure
development, fuel purchases, marketing, and effluent requirements
Summary of Findings:
⢠Substantial associations between hydro-meteorological anomalies
and PDO, TAG, and WPWP DCV patterns in the basin
⢠Need for climate and societal impacts information about decadal
droughts and wet periods
⢠Users beginning to think how they would use decadal climate and
impacts information, even the current phases of major DCV phenomena
⢠Many potential barriers to producing and using decadal climate outlooks,
but users eager to work with climate scientists
⢠Missouri River Basin a very important and âfertileâ region to sow seeds
of climate services, but sustained efforts required to build credibility
of climate science and scientists

14. Predictability and Prediction of Decadal Climate and its Societal
Impacts in the Missouri River Basin: A Regional Study Integrating
Earth System, Hydrologic, Agricultural, Economic and Land Use
Models
⢠2011-2014
⢠Center for Research on the Changing Earth System, Texas A&M University
Specific Objectives:
(1) assess simulations and hindcasts of two decadal climate variability (DCV) phenomena (PDO
and TAG) and their effects on the Basin's hydro-meteorology by global EaSMs (GEaSMs)
(2) downscale simulated and hindcast data from relatively coarse resolution GEaSMs to
relatively high resolution as input to water and crop yield models
(3) quantify decadal predictability of water and crop yields in the Basin, using downscaled
GEaSM data and HM observations-based DCV scenarios in HUMUS-SWAT model
(4) quantify value of adaptive actions given decadal predictions of water and crop yields in
terms of potential economic and other impacts, using FASOM and RIVERSIM models
(5) develop an experimental decadal climate and impacts prediction system for the Basin using
hydrologic, crop, and economic models; and downscaled data from GEaSMs, along with
DCV scenarios based on observed HM data; and assess their effectiveness via interactions
with stakeholders and policymakers.

with most junior water rights
25. Concluding thoughtsâŚ
⢠Our assessments are largely project-based; few basin-wide
⢠Several studies qualitative / some quantitative (or both)
⢠Progression toward more quantitative/integrated assessments
⢠Integration can be challenging
⢠Integrating models and perspectives
⢠obtaining data; identifying meaingful vulnerability metrics
⢠Some local resistance to climate change funding and
adaptation (e.g. grant proposals and farmer/advisor survey)
