Gale force for coastal areas, between and . The definition is very non-standard. A common alternative definition of the maximum is . The most common way of measuring wind force is with the Beaufort scale which defines a gale as wind from to . It is an empirical measure for describing wind speed based mainly on observed sea conditions. On the original 1810 Beaufort wind force scale, there were four different "gale" designations whereas generally today there are two gale forces, 8 and 9, and a near gale 7: The word "gale" is derived from the older "gail", but its origin
Wind lens Wind lens The wind lens is a modification on the wind turbine created by Professor Ohya from the Kyushu University as an attempt to be more efficient in production of electricity and less invasive to both humans and nature. While still in progress, the wind lens has a few changes in design which have led to impacts on how wind energy can be used and harnessed while changing how it impacts the world around us. As the normal wind turbine does, the wind lens harnesses the energy of the wind but has a few modifications in order to increase efficiency
