面对镜头,天气播报员经常用蜡笔或记号笔在气象图上勾画,20世纪70年代,艾伦的天气符号被BBC采用的同时,美国电视台也开始使用它们自己的磁铁天气符号。20世纪80年代,电脑制图的出现带来了更多标准化的、低解析度的天气符号:“只有16种色彩可以上色,”丹佛的气象学家,在“彩图气象系统”公司工作的麦克·尼尔森(Mike Nelson)说,“所以没法太有创意。”
By the late 1980s, computer systems were advanced enough that stations could select their own custom-made graphics. And when weather forecasts made their way to websites and mobile apps, things became even more customized. Around 2000, a government meteorologist in Texas named Dennis Cain made a set of icons from photographs — rainy streets, wind turbines, headlights in the fog — which became the standard images on weather.gov.
到20世纪80年代末,电脑系统有了长足的进步,电视台可以选择自行定制的天气符号。当天气预报出现在网络和移动应用上之后,这些符号就更加个性化了。2000年前后,得克萨斯州一个名叫丹尼斯·凯恩(Dennis Cain)的政府气象学家用照片做了一套符号——下雨的街道、旋风、大雾中的汽车灯光——它们成了weather.gov网站的标准符号。
Like other weather icons, Cain's have fierce adherents. When the National Weather Service said it might swap the photo icons for more conventional figures, it received 18,000 comments in the first few days — most angry. The BBC faced similar outrage when it retired Allen's icons in 2005. Weather symbols "can get very controversial very quickly," says Robert Bunge, who was the director of Internet services for the National Weather Service at the time. "You can get buried in it."
