Anemometer constant torque and responded more quickly to gusts than the four-cup anemometer. The three-cup anemometer was further modified by the Australian Dr. Derek Weston in 1991 to measure both wind direction and wind speed. Weston added a tag to one cup, which causes the cupwheel speed to increase and decrease as the tag moves alternately with and against the wind. Wind direction is calculated from these cyclical changes in cupwheel speed, while wind speed is determined from the average cupwheel speed. Three-cup anemometers are currently used as the industry standard for wind resource assessment studies & practice. One of the
Individual Deprivation Measure action. The IDM can help governments and organisations target poverty more effectively as well as help them measure success or failure, revealing what aspects of poverty are changing, by how much and for whom. The IDM is the first poverty measure in the world based on the views of women and men with lived experience of poverty. The dimensions were informed by how women and men think poverty should be defined and what needs to improve in order to move out of poverty.
