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 and the wind speeds associated with the damage listed aren't rigorously verified. The Enhanced Fujita Scale was formulated due to research which suggested that the wind speeds required to inflict damage by intense tornadoes on the Fujita scale are greatly overestimated. A process of expert elicitation with top engineers and meteorologists resulted in the EF scale wind speeds, however, these are biased to United States construction practices. The EF scale also improved damage parameter descriptions. The original scale as derived by Fujita was a theoretical 13-level scale (F0–F12) designed to smoothly connect the Beaufort scale and the Mach number scale.
