12Substantial Advances in Understanding of Weather
Systems and Basic Processes.
13But 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.
14Warning Signs
- The skill of the GFS, the main U.S. global
weather prediction model, lags that of others
(e.g., ECMWF).
15500 mb Height--24h
16The 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.
17Warning 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?)

21Warning Signs
- Although weather prediction is essentially
probabilistic, the community has held to a
deterministic paradigm, failing to provide our
users with critical probabilistic information.
22A 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.
23Exact Forecasts Out Several Days at Every
Location!
24Starving 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)
25The 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.
26Iconology
And what does probability of precipitation really
mean? A large proportion of the population
doesnt really know.
27Short-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.

32Increasing 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
Penn. Senator Santorum (a.k.a., the Senator from
Accuweather)

35And Other Tensions
- NCAR and NCEP over the development of a new
national mesoscale model (WRF)
36Inefficient 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.
37Lack 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!
38Too 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.
39The 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.
40The 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
41These Issues Have Developed at the Same Time as
the U.S. Meteorological Community Has Experienced
Great Structural Changes
42Structural 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.
43The 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.
44Still 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)
45A Number of Groups Have Realized We Have a Problem
46Pielke 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.
47National 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.
48NRC 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)
49Weather Coalition Private Sector/University
Lobbying Group for the Enterprise
50New AMS Commission on the Weather Enterprise
51Community Meeting on the Weather Enterprise (July
2005)
52How Do We Fix the Problem?
53Some Concrete Suggestions
54Reduce 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.
55The 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?
56One Approach Expand the Role of the
Developmental Test Center
57The 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.
58Major 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.
59Our Past
Our Future!
60The fault, dear Brutus, is not in our stars, but
in ourselves
61The End
62The 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.
63Northwest 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
64The 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.
