Key discussion points for today
Key Discussion Points for Today

  • Implications of new Maritime Strategy

    • Africa Partnership Station

  • Initiatives and priorities related to Tropical Cyclone Research

    • RTPs

    • NPOESS

    • NUOPC

Maritime strategy oct 2007 a cooperative strategy for 21 st century seapower
Maritime Strategy Oct 2007“A 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 Nation’s 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

Maritime strategy implications for naval oceanography
Maritime Strategy – Implications for Naval Oceanography

  • Warfighting readiness:

    • Environmental support globally

    • Leverage R&D 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

Africa partnership station
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

Rapid transition process rtp
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

Rtps applied to tropical cyclones
RTPs Applied to Tropical Cyclones


  • FY 2001: Improvements to Tropical Cyclone Model Forecasts

  • FY 2002: Modeling Tropical Cyclone Structure and Track


  • FY 2006: 4DVAR for Global Atmospheric Weather Prediction

  • FY 2007: Quantifying Uncertainty through Global and Mesoscale Models

  • FY 2008: High Resolution NOGAPS

4dvar for global atmospheric weather prediction
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

Quantifying uncertainty through global and mesoscale models
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

High resolution nogaps
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


  • 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.

Npoess sensors
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 (

    • Host imagery products

    • Currently includes WINDSAT, AMSU, AMSR

    • Will likely include METOP, NPP, NPOESS derived products

NPOESS Sensors: TC Structure

SSM/I 37 GHz H-Pol


If based on WINDSAT design (large antenna), then resolution at all frequencies is improved over


Compare 37GHz images to the right, note improved resolution, and thus enhanced TC Structure, with WINDSAT 37GHz

Note structure of spiral bands, inner core, and double eye wall

National unified operational prediction capability partnership nuopc


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
