CHAPTER 5
WEATHER FORECASTING
Weather Forecast

A prediction of weather conditions
expected at a place, within an area,
or along a route for a specified time
or during a specified period
The civilian weather agency is the
National Weather Service.
National Weather Service

An agency of the National Oceanic
and Atmospheric Administration
responsible for meteorological
observations, weather forecasts,
storm, and flood warnings, etc.
The National Oceanic and Atmospheric
Administration (NOAA) is part of the
Department of Commerce.
National Oceanic and
Atmospheric Administration

A division of the Department of
Commerce, created in 1970, that
conducts research on the world’s
oceans and atmosphere
The National Weather Service is
composed of a headquarters at Camp
Springs, Maryland, six national support
centers, and six regional headquarters.
The six regional headquarters support
field activities throughout the United
States, Puerto Rico, and on some of the
islands of the Pacific Ocean.

The National Weather Service also
receives weather data from some
12,000 substations, most of which
are manned by volunteers.
Chief among the six national support
centers is the National Centers for
Environmental Prediction.
The National Centers for Environmental
Prediction are a group of nine specialized
centers that focus on one aspect of the
overall national warning and forecasting
process. They include:

• Aviation Weather Center, Kansas City, MO
• Climate Prediction Center at the NWS
  headquarters, Camp Springs, MD
• Space Environment Center, Boulder, CO
• Storm Prediction Center, Norman, OK
• Tropical Prediction Center (also known as
  the National Hurricane Center), Miami, FL
The National Weather
                   Service:

                   • Employs several
                     thousand people
                   • Operates 400 weather
                     facilities in the U.S.
                   • Operates 13 weather
                     facilities overseas

                   • Has weather facilities
      Service        on 21 ships
 Tallahassee, FL
Each day, the National
             Weather Service processes:


• 12,000 synoptic reports and 25,000
  hourly reports from surface
  observation stations
• 1,400 reports from ships
• 1,500 atmospheric soundings
• 2,500 reports from aircraft
• Cloud and temperature data from
  weather satellites
Synoptic

Pertaining to or constituting a
synopsis; affording or taking a
general view of the principal
parts of a subject
The National Weather Service provides
weather information to newspapers,
radio and television stations, and other
media for the general public.
The National Weather Service makes studies of
climate and conducts basic and applied research
to improve future forecasts and services, and to
advance the science of meteorology itself.
Much of the National Weather Service's
day-to-day activity is geared to the service of
aviation. Several High Altitude Forecast
Centers have been set up to forecast high-
altitude conditions for commercial airlines.

NOAA, is within what U.S. department?

Each of the services maintains its own
weather agency. The Navy Weather
Service is part of the Navy Meteorology
and Oceanography Command.
Navy Meteorology and
    Oceanography Command

U.S. Navy command whose mission is to
collect, interpret and apply global
meteorological and oceanographic data
and information for safety at sea, strategic
and tactical warfare and weapons
system design, development and
deployment
The U.S. Navy is an active participant in
the World Meteorological Organization.
World Meteorological Organization

Coordinates weather data collection
and analysis by more than 178 member
nations and territories; based in
Geneva, Switzerland
Navy weather units are maintained:

• With all major aviation units
• With certain major combatant and
  auxiliary vessels, and flagships
• At most naval shore activities
Trained enlisted aerographer's mates
and meteorological officers are
assigned to weather units.
On ships that do
not carry
aerographers and
meteorologists,
weather
observations
and reporting are
carried out by the
ship's navigator,
assisted by
trained
quartermasters.
The Naval Meteorology and Oceanography
Centers (NMOCs) use basic information
acquired from various sources, compile
it into weather broadcasts and warnings,
and transmit it to operating forces within
their area of responsibility.
The NMOCs are located at:
• Pearl Harbor, Hawaii
• San Diego, California
• Norfolk, Virginia
• Yokosuka, Japan
• Rota, Spain
• Bahrain in the Persian Gulf


The Fleet Numerical
Meteorology and
Oceanography Center
is located in Monterey,
California.

The National Weather Service publishes
many kinds of weather forecasts:




           • 24-hour detailed forecasts
           • 5-day forecasts
The National Weather Service publishes
many kinds of weather forecasts:




• 30-day general outlooks
The National Weather Service publishes
many kinds of weather forecasts:




• 12-hour aviation forecasts
• Special bulletins, weather maps, and
  storm and frost warnings
Newspapers, TV, and radio weather
reports rely on many of the National
Weather Service forecasts.
Complete weather reports are given
to pilots. They also receive in-flight
updates of weather information.
There are two kinds of weather
reporting, local and long-range
forecasting.
The long-range study is more concerned
with an overall view of the climate and
with predictions a year or more in the
future. Almanacs provide long-range
weather predictions.
Almanac

A publication containing astronomical
or meteorological information
Local weather is predicted up to a month
or so in advance. The accuracy of these
predictions is dependent upon timely
readings taken at many reporting
stations. It is not an exact science.
Weather Reporting Stations, Weather
Ships, Balloons, and Weather Satellites
Elements of the Navy Meteorology and
Oceanography Command prepare
several types of forecasts:
• Area
• Local
• Route
• Flight
• Terminal
• Storm Warnings
• Special Warnings
Major units afloat and ashore prepare
area forecasts. They provide:

• Synopsis of weather conditions

• Report of all pressure systems and
  associated weather, including position,
  intensity, direction of movement
Ships and stations plan and use local
forecasts.
They provide:

• Brief summary of synoptic pressure
  situation, fronts, severe weather, fog

• Normally 36-hour predictions

• Specific details affecting operations
  such as flying conditions, ceilings
The route forecast refers to weather
conditions along a specific route.
The flight forecast pertains to the
weather conditions on successive
stages of a flight.
The terminal forecast concerns itself
with the landing and takeoff conditions
at fields en route.
Storm warnings are included in
scheduled broadcasts to both the fleet
and merchant marine. Thunderstorms,
tornadoes, local windstorms, and major
cyclonic storms are reported.
Special warnings are issued for
hurricanes.

cameras that transmit pictures of cloud
formations by day or night. Other sensors
relate surface temperatures, fronts,
storms, snow, sea ice, and cloud heights.
