History of surface weather analysis

The use of weather charts in a modern sense began in the middle portion of the 19th century. Weather map pioneers include William Charles Redfield, William Reid, Elias Loomis,{{cite journal|title=American Pioneers in Meteorology|journal=Monthly Weather Review|date=July 1933|volume=61|issue=7|url=http://docs.lib.noaa.gov/rescue/mwr/061/mwr-061-07-0189.pdf|access-date=10 February 2011|author=Eric R.

The U.S. Army Signal Corps inherited this network between 1870 and 1874 by an act of Congress, and expanded it to the west coast soon afterwards. Three times daily, all stations would telegraph in their observations to the central office which would then plot the information on a map upon which isobars, or lines of equal pressure, would be drawn which would identify centers of high and low pressure, as well as squall lines.NOAA.

At first, all the data on the map was not taken at exactly the same time in the early days of these analyses because of a lack of time standardization. The first attempts at time standardization took hold in the Great Britain by 1855. However, in the United States, standard time did not come to pass until 1883, when time zones started to come into use across America for railroad use. The entire United States did not finally come under the influence of time zones until 1905, when Detroit finally established standard time.WebExhibits.

The earliest surface analyses from the United States featured a map of the continental U.S. with indications of cloud cover and wind direction arranged on an early form of what has become a station model. A general indication of the weather for various cities around the country was also included on the bottom of the map. Within a short time, the Signal Corps added a tables showing eight-hour pressure change, 24-hour temperature change, relative humidity, and 24-hour precipitation. The Signal Office also added a general discussion of synoptic weather features and forecast, before adding isobars and isotherms onto the maps. By the end of 1872, the maps had established the format it would use until the introduction of frontal analysis.NOAA Central Library.

By the 20th century, most of the weather-related functions under the U. S. Signal Corps branched off into a new civilian agency known as the U. S. Weather Bureau, the forerunner of today's National Weather Service.

Internationally, other countries followed the lead of the United States, in regards to taking simultaneous weather observations, starting in 1873.NOAA.

The New York Daily Graphic published weather maps from mid-1879 through the summer of 1882. By 1894, there were four daily newspapers publishing weather maps in Boston, New Orleans, Cincinnati, and San Francisco.{{cite journal|url=https://books.google.com/books?id=r3M2AQAAMAAJ&pg=PA100-IA3|journal=The American Meteorological Journal|volume=11|title=The Newspaper Weather Maps of the United States|author=R.

The use of frontal zones on weather maps did not appear until the introduction of the Norwegian cyclone model in the late 1910s, despite Loomis' earlier attempt at a similar notion in 1841.David M.

An increasing amount of newspapers published weather maps early in the century across the United States, before the fad passed in 1912. While the number of newspapers carrying weather maps decreased beyond 1912, many continued publishing them until interest in flight increased interest in the maps once more in the 1930s.{{cite book|url=https://books.google.com/books?id=8jUimObl_C8C&pg=PA55|title=Ten Geographic Ideas that Changed the World|author=Susan Hanson|page=54|date=1997|isbn=978-0813523576|publisher=Rutgers University Press}} Beginning in 1930, radiofax broadcasts of weather information and forecasts were broadcast for use by ships at sea, emanating from the United States military and the United States Weather Bureau on a cooperative basis.{{cite web|url=http://www.nws.noaa.gov/os/marine/radiofax.htm|date=2013-10-18|access-date=2014-01-18|title=National Weather Service Marine Broadcasts:Radiofax|author=National Weather Service|publisher=National Oceanic and Atmospheric Administration}} Starting in 1935, Weather Bureau/National Weather Service weather maps were published in newspapers via the Associated Press in a slightly processed format as Wirephoto weather maps.{{cite book|url=https://books.google.com/books?id=tx8XR_6IMeAC&pg=PA117|title=Maps with the News: The Development of American Journalistic Cartography|author=Mark Monmonier|page=117|publisher=University of Chicago Press|date=1989|isbn=978-0226534114}}

By 1999, computer systems and software had finally become sophisticated enough to allow for the ability to underlay on the same workstation satellite imagery, radar imagery, and model-derived fields such as atmospheric thickness and frontogenesis in combination with surface observations to make for the best possible surface analysis. In the United States, this development was achieved when Intergraph workstations were replaced by n-AWIPS workstations.Hydrometeorological Prediction Center.

Recent advances in both the fields of meteorology and geographic information systems have made it possible to devise finely tailored products that take us from the traditional weather map into an entirely new realm. Weather information can quickly be matched to relevant geographical detail. For instance, icing conditions can be mapped onto the road network. This will likely continue to lead to changes in the way surface analyses are created and displayed over the next several years.Saseendran S. A., Harenduprakash L., Rathore L. S. and Singh S. V.
