''Weather Machine'' is a lumino-kinetic bronze sculpture and columnar machine that serves as a weather beacon, displaying a weather prediction each day at noon. Designed and constructed by Omen Design Group Inc., the approximately tall sculpture was installed in 1988 in the northwest corner of Pioneer Courthouse Square in Portland, Oregon, in the United States. Two thousand people attended its dedication, which was broadcast live nationally from the square by ''Today'' weatherman Willard Scott. The machine cost $60,000. During its daily two-minute sequence, which includes a trumpet fanfare, mist, and flashing lights, the machine displays one of three metal symbols as a prediction of the weather for the following 24-hour period: a sun for clear and sunny weather, a blue heron for drizzle and transitional weather, or a dragon and mist for rainy or stormy weather. The sculpture includes two bronze wind scoops and displays the temperature via vertical colored lights along its stem. The air quality index is also displayed by a light system below the stainless steel globe. Weather predictions are made based on information obtained by employees of Pioneer Courthouse Square from the National Weather Service and the Department of Environmental Quality. Considered a tourist attraction, ''Weather Machine'' has been called "bizarre", "playful", "unique", and "wacky", and has been compared to a giant scepter. ==Description and history== ''Weather Machine'' is a lumino-kinetic bronze sculpture that serves as a weather beacon, designed and constructed by Omen Design Group Inc. Contributors included Jere and Ray Grimm, Dick Ponzi, who won a 40-entry international competition to design the machine for Pioneer Courthouse Square (1984), and Roger Patrick Sheppard. The group described their efforts as "collaborative", but Sheppard considered Ponzi the "maestro" of the project.〔 Ponzi did the engineering and hydraulics, and the machine was assembled at his vineyard near Beaverton.〔 The sculpture was inspired by Portland-born-and-based writer Terence O'Donnell, who suffered from osteomyelitis during his childhood,〔 and his "funny Irish jig". ''Weather Machine'', which took five years to plan and build〔 and cost $60,000, was installed in the square in August 1988. ''Today'' weatherman Willard Scott broadcast live from the square to dedicate the sculpture on its August 24 opening. Two thousand people were present as early as 4 a.m. for the dedication.〔 Financial contributors included Pete and Mary Mark, the AT&T Foundation, Alyce R. Cheatham, Alexandra MacColl, E. Kimbark MacColl, Meier & Frank, the Oregon Department of Environmental Quality, David Pugh and Standard Insurance Company.〔 Information about the donors was included on a plaque added to the sculpture's stem in the weeks following the dedication. Each day at noon, the columnar machine performs a two-minute sequence that begins with a trumpet fanfare of the opening bars of Aaron Copland's ''Fanfare for the Common Man'', and produces mist and flashing lights. It eventually reveals one of three metal symbols: a stylized golden sun ("helia") for clear and sunny weather, a blue heron (Portland's official bird)〔 for drizzle and transitional weather, or mist and a "fierce, open-mouthed" dragon for heavy rain or stormy weather.〔〔 The fanciful symbols change at the same time every day, representing weather predictions for the following 24-hour period. "Helia", described as "gleaming",〔 was designed by Jere Grimm; her design would later be applied to one of her husband's pots, exhibited in 1989. The trumpets are allowed to play at noon due to a waiver of Portland's noise ordinance for that time period.〔 Ray Grimm constructed the blue heron symbol, and the group collaborated on the dragon symbol based on his drawings.〔 In order for the machine to display an accurate weather prediction, as reported by ''The Oregonian'' in 1988, employees of Pioneer Courthouse Square contacted the National Weather Service each morning at 10:30 a.m. for the forecast, and then entered information into the machine's computer, located behind a nearby door.〔 The machine, whose height is reported to be between ,〔〔〔 includes two bronze wind scoops that turn in opposite directions.〔〔 It also indicates the temperature (when 20 °F or above)〔 via vertical colored lights along the sculpture's stem.〔〔〔 Measured by an internal gauge, the machine displays blue lights for below freezing, white lights for above freezing and red lights to mark every ten degrees (°F).〔 Referring to an additional light system (below the stainless steel globe) that indicates air quality, ''The Oregonian'' reported in 1988 that a green light indicates good air quality, amber reflects "semismoggy"〔 air and a red light indicates poor air quality.〔 However, in 1998 one writer for ''The Oregonian'' warned: "you don't want to breathe so much when the white light is on".〔 Pioneer Courthouse Square employees enter air quality information into the machine's computer following routine checks with the Department of Environmental Quality.〔 In addition to its pre-dawn dedication on national television, ''Weather Machine'' had a public dedication at noon on August 24, attended by Mayor Bud Clark and other city officials.〔〔 On that day, the machine displayed the sun symbol and a green light for good air quality, and indicated a temperature of . Following the fanfare, known officially as "Fanfare for Weather Machine with Four Trumpets", jazz singer Shirley Nanette led the crowd in a rendition of "You Are My Sunshine".〔 Portland had good weather in the days following its dedication, preventing visitors from seeing all three symbols for an extended length of time (though all three symbols are displayed briefly during the daily two-minute sequence). This prompted the executive director of Pioneer Courthouse Square to consider altering the machine's schedule so that the public would have a chance to see all three symbols.〔 The sculpture maintained good health until winter 1995, when its mechanical performance temporarily began deviating from noon and the temperature gauge had difficulties working properly. In 2012, the machine malfunctioned and stopped operating for about a week.〔 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「Weather Machine」の詳細全文を読む スポンサード リンク
