nephoscope
Noun: A nephoscope is a scientific instrument designed for observing and measuring clouds. Its primary function is to determine the altitude, direction, and speed at which clouds are moving across the sky.
The word nephoscope is a technical term used almost exclusively in meteorology (the science of weather) and atmospheric sciences. It refers to the specific instrument itself. * The meteorologist used a nephoscope to track the storm system's approach. * Early weather stations were often equipped with a nephoscope for basic cloud observation.
- Instrument Classification: A nephoscope is categorized as a type of ceilometer (a device for measuring cloud height), though it is a more direct, optical instrument compared to modern laser-based devices.
- Historical Context: While crucial in the early development of synoptic meteorology (weather forecasting using simultaneous observations), the classic nephoscope has been largely superseded by satellite imagery, radar, and automated sensors.
- Nephology (n): The branch of meteorology concerned with the study of clouds.
- Nephogram (n): A photograph or chart of clouds.
- Ceilometer (n): A modern device that measures cloud height, often using a laser or other light source.
- Cloud-measuring instrument: A descriptive synonym.
- Cloud tracker: A simpler, non-technical term for its function.
The word nephoscope has only one specific meaning related to meteorological instrumentation. It does not have other common definitions.
There are no common idioms or phrasal verbs associated with the highly technical word nephoscope.
- a measuring instrument that uses a grid for measuring the altitude, direction, and velocity of movement of clouds
