KWO35 (the third character is the letter "O") is a NOAA Weather Radio (NWR) station that serves the greater New York metropolitan area (which comprises New York City and the surrounding counties and municipalities in the Tri-state area), as well as marine interests from Sandy Hook, New Jersey to Fire island, New York (out to 40 miles from the Atlantic coastline), as well as New York Harbor, the western Long Island Sound, and the Long Island South Shore Base, and extending southward from Sandy Hook, to Little Egg Inlet NJ (out to 40 miles from the Atlantic coastline) (see County Cov. section for all marine zones). Programming originates from the National Weather Service weather forecast office (WFO) in Upton, New York (located east of New York City, on the grounds of Brookhaven National Laboratory, in central Suffolk County on eastern Long Island). The transmitter, located in Manhattan, was originally atop 30 Rockefeller Plaza (known then as RCA Building) in Rockefeller Center. It was eventually moved to 200 Park Ave (a.k.a. MetLife Building). In July 2013 interference with Coast Guard radio transmissions became a public safety issue, forcing KWO35 off-the-air for long periods. In March 2014 the transmitter was relocated atop a building near Times Square in an effort to mitigate disruptions in service, with primary and secondary transmitters tested for interference at a new location. A planned new, permanent, and more powerful transmitter was announced (transmitter issues are discussed below). When operational, the station broadcasts 24 hours per day on a frequency of 162.55 MHz (one of seven VHF radio frequencies allocated by the U.S. Government for NWR transmissions, known collectively as "weather band"), with a power output of 1000 (formerly 750) Watts. On modern weather radio receivers it is often marked "Channel 7". KWO35 broadcasts weather and civil hazards information for the following counties within its coverage area: Bronx, Kings, Nassau, New York, Queens, Rockland, Richmond, () Suffolk, and Westchester counties in southeastern New York; Bergen, Essex, Hudson, Hunterdon, Middlesex, Monmouth, Morris, () Ocean, Passaic, Somerset, () Sussex, Union, and () Warren counties in northern and central New Jersey; () Fairfield County in southwestern Connecticut. In addition to broadcasting routine weather and marine forecasts and conditions, the station will also transmit public information statements, short term forecasts, special weather statements, advisories, watches and warnings issued by the WFOs in Upton, New York and Mount Holly, New Jersey when hazardous weather conditions threaten the coverage area. In severe weather situations, the NWR ''Public Alert system'' may be used to activate specially-equipped weather band receivers, using both ''Specific Area Message Encoding'' (SAME) and 1050 Hz alert tones. Radios that are SAME-capable can be configured to sound local alerts only (for specific counties) by programming in the corresponding ''Federal Information Processing Standards'' (FIPS) codes. ==Service (un)reliability, then return== There have been numerous interruptions in service due to the lack of a backup power supply (most notably during the 2003 blackout) and limited redundancy in communications. 〔http://massis.lcs.mit.edu/archives/back.issues/2002.volume.20/vol20.iss301-350〕 〔http://catless.ncl.ac.uk/Risks/24.07.html#subj4〕 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「KWO35」の詳細全文を読む スポンサード リンク
