Cold, Hard Data
Photograph by Jay Dickman
Mount Washington in New Hampshire is said to have the worst weather on Earth, but that's partly because the observatory on the summit documents it all—high winds, sub-zero temperatures, and lots of snow, measured with a precipitation can that is lugged inside every six hours. All the data is transmitted to the National Weather Service, which gathers observations from a global network of surface stations, ships, weather buoys, balloons, aircraft, and satellites. Meteorologists input this mountain of data into supercomputers that model the behavior of weather systems with greater accuracy than ever before: Today's 72-hour forecast is as reliable as the 36-hour forecast was 25 years ago.
