Force Ten (song) worked with Rush on their song "Tom Sawyer", had sent Neil Peart some lyrics for the song, and Peart would add more verses to it. Lyrically, the song describes the "storms of life," making a reference to a very high level of the Beaufort scale ("force ten" is defined as a 'storm', being near the scale's maximum of 12) as an analogy, according to the book "Rush and Philosophy: Heart and Mind United". Musically, "Force Ten" is composed in A minor, with changes into A major scale occurring in the song. The song is set in common time at a
Saffir–Simpson scale low-cost housing in hurricane-prone areas. While conducting the study, Saffir realized there was no simple scale for describing the likely effects of a hurricane. Mirroring the utility of the Richter magnitude scale for describing earthquakes, he devised a 1–5 scale based on wind speed that showed expected damage to structures. Saffir gave the scale to the NHC, and Simpson added the effects of storm surge and flooding. In 2009, the NHC made moves to eliminate pressure and storm surge ranges from the categories, transforming it into a pure wind scale, called the Saffir–Simpson Hurricane Wind Scale (Experimental) [SSHWS]. The new
