  "term": "Weber-Fechner law",
  "field": "Meteorology and atmospheric science",
  "definition": "A psychological principle stating that the perceived intensity of a stimulus is proportional to the logarithm of its physical intensity. In atmospheric science, it is applied to human perception of weather phenomena, such as the apparent brightness of the sky or the loudness of thunder. The law implies that for a change in a stimulus to be noticeable, the physical intensity must increase by a constant percentage of its current level, not by a constant absolute amount.",
