The world's oldest mountain observatory is the meteorological observatory at Hohenpeissenberg, situated in the foothills of the Alps about 60 kilometers (37 miles) southwest of Munich.
Meteorological measurements began there in 1781, and the station constantly works on "methods to improve weather forecast and emergency alerts," according to its website. From the start, it was part of a weather observation network including dozens of stations spread out from the Ural Mountains in Russia to North America and from Greenland to the Mediterranean Sea.
While scientists now use algorithms and large amounts of data for weather forecasts, early weather predictions usually relied on persistence, experience and watching wildlife and recurring natural phenomena.
