In the early days of the telegraph, station operators began sharing the local weather with each other. As the practice became more widespread, people started to realize that what happened in one location translated to later events in another location. Modern weather forecasting and the concept of weather systems were born.
The operators had discovered something both interesting and paradoxical, the writer Andrew Blum observes in his book The Weather Machine. The telegraph had collapsed time but, in doing so, it had somehow simultaneously created more of it. Now people could see what the future held before it happened; they could know that a storm was on its way hours before the rain started falling or the clouds appeared in the sky. This new, real-time information also did something else, Blum points out. It allowed weather to be visualized as a system, transforming static, localized pieces of data into one large and ever-shifting whole.
