VOA标准英语2009年-Almanac Predicts Colder Than Normal Winter(在线收听) |
By Sarah Williams "We expect heavier than normal snow in the Intermountain region, which is in the vicinity of the Rocky Mountains, and just colder than normal temperatures throughout most of the U.S.," said Janice Stillman, the Almanac's editor. She claims the forecasts made by the Old Farmer's Almanac are 80 percent accurate. To make those predictions, the Almanac has traditionally used a secret formula based on sunspot activity developed in 1792 by its founder, Robert B. Thomas. Today, it also employs what it calls state-of-the-art technology and modern scientific calculations.
Some scientists claim the vagueness of the Almanac's predictions makes it difficult to determine their accuracy. So does the fact that the Almanac's predictions are prepared as much as 18 months in advance. In a concession such challenges, the Almanac stated in its bicentennial edition, "Neither we nor anyone else has as yet gained sufficient insight into the mysteries of the universe to predict weather with anything resembling total accuracy."
