The daily weather forecast is something you think must have always been around, but in fact it wasn’t until the second half of the 19th century that a reasonably accurate forecast could be made. The key requirements were a near-simultaneous view of current weather conditions at multiple geographically separated stations (made possible by the electric telegraph, and presented on a map), together with an understanding of how weather systems move in time and space (an understanding that improved over time based on the ever-growing history of past weather observations to compare against). Surprisingly, given how popular the weather forecast is today, it wasn’t really until the 1910s that the daily weather forecast and map became a feature in most newspapers.
The first chapter of this book was great, showing a weather map prepared in advance of an 1898 storm that swept across New England, and explaining the meteorological information that one could deduce from the map, to show how the storm could have been foreseen and a catastrophic loss of life avoided. But the rest of the book didn’t quite live up to the promise of this initial chapter.
While it covers both, “Air Apparent” spends more time on the evolution of the weather map than on how weather systems work and how weather forecasting has improved. The mapping aspect was less interesting to me, and I’m someone who usually loves maps. The visual differences in weather map presentation are just not all that striking or interesting, and a small, mostly black-and-white volume isn’t the ideal vehicle to show the differences that do exist. The book is also pretty badly dated (published in 1999) in some aspects due to its overly detailed descriptions of specific visualization technologies that have been superceded.
So unless the cartographic aspect is of particular interest to you, this book is pretty niche and there are probably better books out there on weather forecasting.
