Title: National Hurricane Conference Navy Priorities and Initiatives for Tropical Cyclone Research


1
National Hurricane ConferenceNavy Priorities
and Initiatives for Tropical Cyclone Research
  • Robert S. Winokur
  • Technical Director
  • Oceanographer of the Navy
  • March 2008

2
Key Discussion Points for Today
  • Implications of new Maritime Strategy
  • Africa Partnership Station
  • Initiatives and priorities related to Tropical
    Cyclone Research
  • RTPs
  • NPOESS
  • NUOPC

3
Maritime Strategy Oct 2007A Cooperative
Strategy for 21st Century Seapower
  • Six key tasks or strategic imperatives
  • Regionally concentrated, forward-deployed task
    forces to limit regional conflict
  • Deter major power war
  • Win our Nations wars as part of a joint campaign
  • Contribute to homeland defense in depth
  • Foster and sustain cooperative relationships with
    more international partners
  • Prevent or mitigate disruptions or crises

4
Maritime Strategy Implications for Naval
Oceanography
  • Warfighting readiness
  • Environmental support globally
  • Leverage RD initiatives to ensure warfighting
    benefits
  • Manage risk and understand uncertainty of
    predictions
  • Partnership building
  • National and international relationships to
    advance common national interests and global
    maritime security
  • Humanitarian assistance and disaster response
  • Rapid and sustained non-combatant evacuations
  • Potential impacts of climate change on
  • natural disasters, social instability and
    regional crises

5
Africa Partnership Station
  • One of a series to build maritime safety and
    security in Africa
  • Focus on Gulf of Guinea
  • Aligned with broad international and US
  • non-military objectives
  • NOAA involvement
  • Fisheries, meteorology, hydrography
  • NOAA Pirata buoy
  • HSV Swift, USS FT. McHenry
  • Training for nine African nations

6
Rapid Transition Process (RTP)
  • Meeting the challenge of timely integration and
    transition from Research (6.2) to Operations
    (6.4)
  • Oceanographer of the Navy / Office of Naval
    Research / Commander Naval METOC Command
  • / Program Executive Office
  • Rapid 3-4 year transition
  • Consistent with CNO Strategic Plan
  • Good Science Clear Impact Navy Relevance

7
RTPs Applied to Tropical Cyclones
  • DIRECT
  • FY 2001 Improvements to Tropical Cyclone Model
    Forecasts
  • FY 2002 Modeling Tropical Cyclone Structure and
    Track
  • INDIRECT
  • FY 2006 4DVAR for Global Atmospheric Weather
    Prediction
  • FY 2007 Quantifying Uncertainty through Global
    and Mesoscale Models
  • FY 2008 High Resolution NOGAPS

8
4DVAR for Global Atmospheric Weather Prediction
  • 4D assimilation provides a continuous picture of
    the atmosphere over the observation time
  • Provides a consistent framework for observations
    of cloud, precipitation, water vapor, ozone and
    aerosols affecting model temperature, humidity
    and wind fields
  • Particularly relevant in data rich NPOESS era

9
Quantifying Uncertainty through Global and
Mesoscale Models
  • Global - mesoscale ensemble forecasting system
  • Provide high-fidelity, dynamically consistent
    probabilistic forecasts and estimates of
    uncertainty
  • Direct support to Tactical decision Aids (TDA)
  • Indirect but important enhancement to TC
    forecasts

10
High Resolution NOGAPS
  • Navy Operational Global Atmospheric Prediction
    System
  • Increased resolution will improve capability to
    assimilate observations and predict finer scale
    features such as TCs
  • Proposed development
  • - 27 km horizontal resolution (current 50 km)
  • - 60 vertical levels (current 30 levels)
  • - semi-Lagrangian moisture advection

11
NPOESS
  • NPOESS Next-Generation Sensors and applications
    to Tropical Cyclone research, modeling, and
    predictability
  • Includes associated algorithm development at Navy
    Centrals (FNMOC and NAVOCEANO), and Ground
    Segments/ IDPS (Interface Data Processing
    Segment)
  • IDPS Installs at FNMOC Monterey and NAVOCEANO
    (completed by November 2012), improving time
    latency and direct ingest into 4DVAR NOGAPS
  • METOP, NPP Exploitation

Improving Quality, Quantity, and Time Latency of
Remotely Sensed Data Critical to improved
diagnosis of intensity change, location of TC
Center, and better track/landfall forecasts.
12
NPOESS Sensors
  • NPOESS Sensors with TC Applications for USN
    include
  • Improved Imaging (VIIRS, MIS)
  • Improved retrievals and soundings (CrIS/ATMS),
    with more channels and higher vertical resolution
  • Hyperspectral capability (CrIS)
  • Possibility of passive ocean surface wind vectors
  • Improved hurricane ocean heat content products
    (NAVO)
  • NRL Monterey Marine Meteorology Tropical Cyclone
    Web Page (http//www.nrlmry.navy.mil/tc_pages/tc_h
    ome.html)
  • Host imagery products
  • Currently includes WINDSAT, AMSU, AMSR
  • Will likely include METOP, NPP, NPOESS derived
    products

(large antenna), then resolution at all
frequencies is improved over SSMI Compare 37GHz
images to the right, note improved resolution,
and thus enhanced TC Structure, with WINDSAT

National Unified Operational Prediction
CapabilityPartnership (NUOPC)
  • Established to enable a Tri-Agency joint global
    atmospheric ensemble forecast system,
  • Integration of on-going efforts coordinated by a
    tri-agency management organization

16
NUOPC Vision (2015)
  • Tri-Agency partnership to address common
    operational global NWP needs
  • National NWP system with interoperable components
    built on common standards and framework (ESMF)
  • Managed operational ensemble diversity
  • Joint ensemble
  • Most probable forecast -- e.g. high impact
    weather
  • Mission Specific ensemble products
  • National global NWP research agenda to accelerate
    science and technology infusion

17
The NUOPC Partnership
  • Coordinated technology development for future
    systems
  • Interoperable model architecture to allow for
    exchange of technology at the component level
  • Common Developmental test structure with
    available tools, support and access to data, data
    assimilation and developmental models (DTC or
    VTC)
  • Prioritization of common operational needs
  • Aligned transition processes
  • Joint ensemble system with managed diversity
  • Share operational computing costs
  • Maintain capability of each agency to meet Agency
    unique operational requirements through driving
    downstream applications
  • Significant acceleration in operational
    performance
  • Project Manager responsible to Tri-Agency
    Executive Steering Group

18
Role of the Meteorological Community
  • Participation in committees defining NUOPC
    concepts and plans
  • Common Model Architecture Committee
  • Technology Transition Processes Committee
  • Unified Ensemble Operations Committee
    (Information Assurance Panel)
  • Support national research and development Agenda
    RD community involvement
  • Support developmental standards and
  • contribute to research needs of the
  • operational community.

19
Where We Are Today
  • Two-year Phase I approved by Agency Principals
  • Full operational capability by 2015 with early
    IOC for select phases
  • Memorandum of Agreement drafted
  • Initial implementation plan and concept of
    operations developed
  • Interim Project Manager selected
  • Committee process approved
  • Requesting nominations for interim committees
  • Town hall session at AMS
  • Scheduling a follow on outreach meeting with
    other Federal agencies (FAA, NASA, NSF, etc.) to
    provide update and reaffirm support

20
In SummaryNavy Remains Committed
  • New Maritime Strategy Cooperative relationships
    and humanitarian assistance
  • Parntnership building
  • Joint programs NUOPC
  • Transition from research to operations RTPS
