Beaufort, Isère In 2012 the commune had 999 inhabitants. The evolution of the number of inhabitants is known from the population censuses conducted in the commune since 1793. From the 21st century, a census of communes with fewer than 10,000 inhabitants is held every five years, unlike larger communes that have a sample survey every year. Beaufort, Isère Beaufort is a commune in the Isère department in the Auvergne-Rhône-Alpes region of south-eastern France. The inhabitants of the commune are known as "Beaufortois" or "Beaufortoises". Beaufort is located some 50 km north-east of Grenoble and 8 km east of Beaurepaire. Access to the
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.
