Weather data comes in a variety of forms
from a number of sources. The data can be obtained from
human reports, in situ instruments, or remote sensors.
Clearly, meteorologists at the National Weather Service, as
well as those at the various private companies, comprise a
significant portion of the users of weather data. However,
for nearly every facet of our population, weather data has a
critical role in decision making. Forecasters use meteorological data to
support a number of programs including public, aviation,
fire and marine. Forecasters preparing public products
routinely monitor temperature data to produce 1 to 7 day
forecasts of temperature. These same values are also used
for verification of their forecasts. Aviation forecasters
keep a keen eye on surface observations for wind shear,
weather or restrictions to visibility that could adversely
affect take-offs and landings. Additionally, conditions
aloft must be monitored to watch for areas of icing or
turbulence. Forecasters support fire weather programs by
watching not only the more common elements of temperature
and wind, but also relative humidity because it can have a
critical impact on the behavior of fires.
For forecasters involved in short term
warning operations, meteorological data is exceptionally
important. Data associated with events that can result in
loss of life and destruction of property such as severe
storms, hurricanes, and extreme winter storms, must be
carefully monitored in order to issue warnings, which are
timely and accurate.
Similarly, to researchers within the field
of meteorology, weather data is an integral component of
their work. Long records of data are used to compile
climatologies. Changes noted within the climatological
records are used to examine climate variability and research
the notion of climate change. For modelers, those who work
on numerical weather prediction, the data are important for
model initialization and also for verification.
However, nearly every member of the
population uses weather data on a regular basis. By thinking
of how weather can affect your travel, activity, and
business decisions, the list of uses and users becomes
longer. And while making a complete list of users and uses
would take more space than is available here, a diverse
range is described here.
Public utility companies need to monitor
extremes in weather to ensure they are prepared to deliver
sufficient electricity or gas to the population.
All areas of the military carefully watch
weather observations as weather can severely impact military
operations as well as their supporting personnel and
equipment.
Those monitoring and predicting air quality
use a variety of weather sources, including upper air
soundings, to watch for conditions resulting in periods of
poor air quality.
Emergency managers monitor weather
conditions to “gear up” for significant weather events.
Many aspects of the weather are critical to
the agriculture community. Farmers must monitor
observations before deciding to plant, irrigate, make hay,
or apply insecticides or fertilizers.
The transportation industry makes a number
of their decisions based on weather. Road and rail
conditions must be monitored for safe travel. Maintenance
workers monitor the data to keep the roads and rail lines
clear. Some high profile vehicles are dangerous to operate
under conditions of strong wind. Some cargo is highly
susceptible to extreme temperatures. Cargo ships could
experience delays or accidents due to areas of large waves.
Travelers do not want to be delayed or stranded. Air traffic
managers must closely monitor changing conditions to
maintain safe conditions and keep delays to a minimum. This
is especially true at larger airports where small changes in
weather can produce substantial impacts.
Many retail operations have seen great
success or dismal returns based on their stock. Retailers
have periods during which they will have an onslaught of
business such as plywood prior to hurricane landfall or
groceries the day before a winter storm.
Commodity traders make a number of decisions
based on weather data. A freeze in Florida could likely
affect the price of citrus or crops.
Constructions workers carefully observe
data, looking for periods to pour concrete or operate a
crane.
Fire fighters watch for changes in the
weather that could affect the growth and spread of a fire,
or the behavior of a hazardous materials spill.
Many specialties in the field of engineering
regularly rely on weather data, and climatologies derived
from the data. Hydrological engineers monitor stream flow,
snow depth and precipitation data. Civil engineers and
architects rely on temperature, precipitation and wind
extremes when designing and building highways, bridges and
buildings. Engineers designing solar or wind energy sources
rely on weather data for site selections.
Weather data supports a wide range of
scientific fields. Entomologists can anticipate sudden
increases or decreases of certain insects based on weather
data. Animal scientists know that certain weather regimes
can have adverse effects on animal populations. Astronomers
and radio specialists plan many of their activities based on
the condition of the atmosphere. Those in the health and
medical field educate patients with respiratory illnesses to
check weather as various medical conditions can be
influenced by changes in any one of several weather
elements.
Marine weather data supports a wide range of
customers from the interests of recreational sailors and
boaters to the interests of commercial fishing companies and
cruise lines.
Are you preparing for a recreational or
sporting activity? Responsible hunters, golfers, hikers,
skiers know to check weather conditions before starting out.
For professional athletes, those maintaining their playing
fields check weather data prior to mowing or covering the
field. And field or track conditions determine the type of
shoe an athlete wears or the tire mounted on a racecar.
Forensic specialists often request official
records of weather data. Weather observations may be used to
determine the cause of an accident, the damage to a
residence or the conditions of a crime scene.
Even though we have not covered all the
uses of weather data, it’s obvious that weather data
influences a wide range of decisions we make for everything
from business to pleasure. The impact on the nation is
virtually incalculable, whether one is considering monetary
benefits or the emotional well being of our people. The
trend proves that weather data will not only remain an
important factor in the decisions we make, but will continue
to increase importance in the years ahead.
