The Wind Off the Small Isles Only two days after arriving there, Cora decides she wants to buy a house. While driving around the island they reach Playa Blanca and Cora sees just the house she is looking for. She sends Perdita to ask who owns it. Perdita, after getting no answer at the front door, meets Michael in the grounds who is supervising building work. There is a mention of Julian Gale from Stewart's earlier novel, "This Rough Magic". The Wind Off the Small Isles The Wind Off the Small Isles is a novella by Mary Stewart, first published in 1968. Unlike her other works,
Fujita scale F1 corresponds to the twelfth level of the Beaufort scale, and F12 corresponds to Mach number 1.0. F0 was placed at a position specifying no damage (approximately the eighth level of the Beaufort scale), in analogy to how the Beaufort's zeroth level specifies little to no wind. From these wind speed numbers, qualitative descriptions of damage were made for each category of the Fujita scale, and then these descriptions were used to classify tornadoes. The diagram on the right illustrates the relationship between the Beaufort, Fujita, and Mach number scales. At the time Fujita derived the scale, little information was
