13
But Even With These Advances We Have Accomplished
Far Less Than Our Potential and in a Number of
Areas the U.S. Have Lost World Leadership
  • This talk will suggest that our progress has been
    undermined by the inability of the major sectors
    of the weather prediction community to work
    together effectively.

14
Warning Signs
  • The skill of the GFS, the main U.S. global
    weather prediction model, lags that of others
    (e.g., ECMWF).

500 mb Height--24h
16
The U.S. Weather Research Programwhose goal was
to coordinate and support the nations weather
research--is essentially dead, ended by a lack of
funding, vision, and interest.
17
Warning Signs
  • Major deficiencies exist in key forecast model
    parameterizations (e.g., planetary boundary
    layer, microphysics) and there is minimal
    community coordination and joint research to deal
    with them.
  • Disturbingly, the intellectual resources needed
    to deal with such major problems are declining.
    (How many PBL researchers are in our department
    now versus 30 years ago?)

21
Warning Signs
  • Although weather prediction is essentially
    probabilistic, the community has held to a
    deterministic paradigm, failing to provide our
    users with critical probabilistic information.

22
A new forecast preparation/dissemination approach
(IFPS) was developed by the NWSthat is
completely deterministic and which burdens
forecasters with producing single renditions of
reality every six hours for seven days.
23
Exact Forecasts Out Several Days at Every
Location!
24
Starving Probabilistic Prediction
  • U.S. efforts to create short-term, mesoscale
    ensembles have been underfunded and inadequate.
  • Virtually no post-processing of ensembles to
    produce reliable probabilistic forecasts (pdfs)

25
The Communication Deficit
  • There has been virtually no research on how to
    best communicate weather information.
  • Current icons are inconsistent and often
    irrational.
  • Icons and other approaches are used with little
    understanding of how people interpret them.

26
Iconology
And what does probability of precipitation really
mean? A large proportion of the population
doesnt really know.
27
Short-Term Forecasting Our Greatest Failing
  • With improving radar, mesonets, short-term NWP,
    and physical understanding, meteorologists know a
    great deal of what is happening now and during
    the next few hours.that is not communicated.
  • Example radar and MM5 indicate a profound
    rain-shadow that will persist for the remainder
    of the day. NWS and media provide forecast of
    scattered showers
  • There has never been as much discrepancy between
    what meteorologists know and what information the
    public gets.

Increasing Tensions Among the Weather Enterprise
  • Tensions have developed among the community,
    particularly at the interface between the private
    and governmental sectors.
  • The private sector feels that the NWS is invading
    their territory with Internet and wireless
    delivery, and is providing custom forecasts to
    potential clients.
  • A group of private sector companies convinced
    Senator Rick Santorum to introduce legislation
    that would limit the NWS to warnings and
    collecting observations/NWP

Accuweather)

35
And Other Tensions
  • NCAR and NCEP over the development of a new
    national mesoscale model (WRF)

36
Inefficient and Poorly Organized Research
Structure in NOAA
  • The government research laboratories that are
    tasked to supply new scientific and technical
    advances for the NWS are OUTSIDE of the
    organization, under NOAAs Office of Atmospheric
    and Oceanographic Research
  • Without direct management by the user agency
    and with research tasks balkanized over many
    labs, the research agenda has been inefficient,
    developing technologies that are unneeded or
    redundant, and not dealing with acute problems.

37
Lack of Critical Mass Too Many Weather
Prediction Models
  • NWS NCEP Eta, GFS, Regional Spectral, WRF-NMM
  • Navy COAMPS, NOGAPS, NORAPS
  • NCAR MM5, WRF-ARW
  • Oklahoma ARPS
  • Colorado RAMS
  • MESO Inc MASS model
  • and several more!

38
Too Many Models
  • Some competition is good, and we dont want to
    put all our eggs in one basket, but we have
    clearly divided the community between too many
    modeling systems for our own good.
  • The NWS and universities have generally used
    different models. Eta has been the main
    mesoscale model for the NWS, MM5 (and now WRF)
    for the academic community. A real problem for
    the transfer of research results to operations.

39
The WRF Model Saga
Same Pronunciation
  • The WRF (Weather Research and Forecasting) model
    was conceived as a way to bring the academic and
    operational communities together under one model
    infrastructure for mesoscale prediction.
  • Plug compatible physics would be easy to switch
    and test.
  • Completely new model with better, numerics, clean
    code and easily parallelized.

40
The Reality
  • The NWS and NCAR went in separate directions with
    different dynamic cores.
  • NWS NMM core
  • NCAR/Universities ARW core
  • The plug compatible physics that would allow
    various cores to use the same physics has not
    panned out.
  • The infrastructurethe software framework that it
    all works in has proven difficult to modify and
    understand.
  • Decision making has been limited to NCAR and a
    few Federal agencies.
  • NWS and NCAR going separate ways on data
    assimilation

41
These Issues Have Developed at the Same Time as
the U.S. Meteorological Community Has Experienced
Great Structural Changes
42
Structural Changes
  • The private sector has grown rapidly and stands
    as an equal to the government and academic
    sectors.
  • The National Weather Service is now a much
    smaller piece of the pie.
  • The boundaries between the sectors have become
    more diffuse.

43
The Boundaries Are Fading
  • All sectors now do NWP
  • All sectors disseminate information to the public
  • (even the universities through their web pages
    and involvement with the mediae.g., Penn. State
    produced weather page in the NY Times)
  • All sectors are involved in data collection.
  • Such overlap is really a very healthy
    development, promoting creativity and
    cross-fertilization, assuming it does not lead to
    conflict and tensions.

44
Still a Giant
  • We (the U.S.) still have many things going for
    us
  • The worlds largest meteorological academic
    community.
  • The largest and most successful private sector
    community.
  • The largest governmental research community.
  • Demonstrated great creativity.
  • But we have not effectively combined our
    resourcesboth intellectual and financialto make
    the rapid progress of which we are capable.
  • Often overseas competitors take our technologies
    and beat us to operational implementation (e.g.,
    4DVAR)

45
A Number of Groups Have Realized We Have a Problem
46
Pielke and Carbone 2002
  • The goals of the weather prediction enterprise
    are unlikely to be reached if the community
    proceeds in a balkanized fashion that has
    characterized it in the past.
  • No organization or entity has embraced the
    collective measure of responsibility for
    improving forecast processes.

47
National Research Council 1998 Report on the
Future of the Atmospheric Sciences
  • Today, there is reason for considerable concern
    about planning for atmospheric research. No one
    sets the priorities no one fashions the agenda.
    Thus, BASC believe that a national research
    environment requires a strong disciplinary
    planning mechanism. ... all partners in the
    atmospheric enterprise in government, in
    universities, and in a variety of commercial
    undertakings must join together as an effective
    team focused on the future.

48
NRC FairWeather Report (2003)
  • Suggests that the various components of the
    Weather Enterprise needs to work together more
    effectively.
  • Provides some potential approaches (e.g., AMS set
    up a neutral arbiter)

49
Weather Coalition Private Sector/University
Lobbying Group for the Enterprise

New AMS Commission on the Weather Enterprise
51
Community Meeting on the Weather Enterprise (July
2005)
52
How Do We Fix the Problem?
53
Some Concrete Suggestions
54
Reduce Tensions
  • NWS should establish an advisory committee that
    is widely representative of the weather community
    and users
  • NWS should amend its partnership policy not to
    support forecast products for specific industries
    or individuals unless dictated by law.
  • The private sector must acknowledge the NWS needs
    to use modern communication technologies.
  • The AMS Commission must expand its role to
    provide venues to discuss Weather Enterprise
    issues.

55
The Community Must Develop Better Mechanisms for
Organizing and Coordinating Development and
Research for Operational and User Needs.
  • What are the deficiencies of the current
    observing, modeling and data assimilation systems
    and how will the resources, both financial and
    personnel, be found to deal with them?
  • How can duplication of effort be reduced?

56
One Approach Expand the Role of the
Developmental Test Center
57
The DTC
  • The DTC was set up as a facility where the
    numerical weather prediction research and
    operational communities will interact to
    accelerate testing and evaluation of new models
    and techniques both to improve the technology and
    for operational implementation.
  • Supported by a number of groups (NCAR, Air Force,
    NOAA, Navy) and is seen as a relatively neutral
    entity.
  • Underfunded now, but could serve as the nucleus
    of a true community effort.

58
Major Components
  • Establish an oversight board representative of
    the entire community.
  • Would hold workshops on important mesoscale
    modeling topics
  • Would establish active working groups on model
    physics, data assimilation, etc. that would
    prioritize and coordinate U.S. efforts.

59
Our Past
Our Future!

The fault, dear Brutus, is not in our stars, but
in ourselves
61
The End
62
The Northwest Example
  • In the Pacific Northwest, a wide-ranging group of
    Federal, state and local agencies, academic
    institutions, and private sector entities have
    combined resources to build a regional weather
    prediction system, using both high resolution
    modeling (down to 4-km grid spacing) and
    mesoscale ensembles.

63
Northwest Modeling Consortium
  • National Weather Service
  • University of Washington
  • USDA Forest Service
  • Port of Seattle
  • United States Navy
  • U.S. Environmental Protection Agency
  • Washington State Department of Ecology
  • Puget Sound Clean Air Agency
  • Washington State Department of Natural Resources
  • Washington State Department of Transportation
  •  Seattle City Light
  • KING TV

64
The Northwest
  • Resources are pooled and decisions are made as a
    group.
  • It took a few years of intense discussion for the
    various sectors to understand and trust each
    other, but this was achieved with very positive
    results.
  • Working together the group has also created a
    wide range of innovative applications in
    Transportation Weather, Hydrology, Air Quality
    Forecasting, and other areas.
