Astronomy:Weather Forecasting
It was known that weather moves in patterns across the sky, but budding weather forecasters faced a major hurdle — they could not see over the horizon, and did not know what weather was on the way. With the invention of the telegraph in the 1830s, it became possible for weather reports to be collected in a variety of locations, and communicated quickly to a central point. And now we have satellites and weather stations to help predict weather correctly.
