Storm Data and Unusual Weather Phenomena(SD) is a monthlyNOAApublication with comprehensive listings and detailed summaries ofsevere weatheroccurrences in the United States. Included is information ontornadoes,highwindevents,hail,lightning,floodsandflash floods,tropical cyclones(hurricanes),ice storms,snow,extreme temperatures such asheat wavesandcold waves,droughts,andwildfires.Photographs of weather and attendant damage are used as much as possible. Maps of significant weather are also included.[1]

Background

[edit]

Storm Datawas started by the Weather Bureau, predecessor to theNational Weather Service(NWS), in 1959. It is updated continuously on a monthly basis with a lag of a few months from the present. This delay is because the data is compiled and verified by local NWS offices and sent to theNational Centers for Environmental Information(NCEI) which does further refinements and publishesStorm Datain reports covering the entire country. The local NWS offices initially gather the data, starting when a severe weather event unfolds and continuing until sufficient information is obtained. The initial data, considered preliminary, is sent in real-time to theStorm Prediction Center(SPC) which does limitedquality controlas new information becomes available and enters it into its (and its predecessor the National Severe Storms Forecast Center) Storm Events Database that begins in 1950. Original sources of the data include but are not limited to local law enforcement, local, state, and federalemergency management,storm spotterandstorm chaserreports, the news media, insurance industry data, NWS damage surveys, and reports from the general public.[1]

SPC is interested in tornado,convective wind,and hail data. The tornado portion of the database, the National Tornado Database, is one of three authoritative tornado databases. Another is the DAPPL (short for Damage Area Per Path Length) database that was headed byTed Fujitaat theUniversity of Chicagoand concerns the period from 1916 to 1992. The most comprehensive historical database was compiled byTom Grazulisof the Tornado Project and exhaustively covers knownsignificanttornadoes for the period from 1680 to 1995. Both the Storms Event Database andStorm Dataare official records. The database and the publication are from the same source but the database is more easily searchable. Delayed reports are added to both the database as well as the publication as new information becomes available in the "Late Reports and Corrections" section.

Until 2012Storm Datawas available to anyone but for a charge. Now it is a free publication downloadable from theNCEI website.

Format

[edit]

Storm Datapublishes chronological tabulations, narratives, and images for a calendar month, as well as updates to previous publications. The format has undergone various changes throughout publication history but consists of reports separated by state subdivided by regions within a state. Type of occurrence, location (including municipality and county as well as estimatedlatitudeandlongitude), date and time, magnitude of event (i.e.wind speed,Fujita scalerating,Saffir-Simpson Hurricane Scalerating, hail size,storm surgeor rivercrestheight, etc.), fatalities and injuries, monetary damages of property and agricultural crops, and descriptions are included. For tornadoes, Fujita scale orEnhanced Fujita scalerating is included as well as path length in miles and path width in yards. Average path width is listed from 1950 to 1994 and maximum path width is listed from 1995 to present.[2]For fatalities, demographic information such as age and sex are gathered when possible as is the type of location (frame house, mobile home, apartment, outside, vehicle, church, school or other public building, etc.) and/or activity (boating, camping, playing sports, golfing, swimming, bathing, telephoning, construction work, etc.) at time of death.[3]

Significantwaterspouts,funnel cloudsightings, densefog,densesmoke,dust storms,dust devils,debris flows(such as landslides),avalanches,tsunamiand other surf and tide events,volcanic ash,as well as other extreme or unusual weather may also be listed. Annual summaries of selected event types are listed in the December issue for older years and in a separate issue for recent years.[4]
