micrometeorology: meaning, definition, pronunciation and examples

Micrometeorology focuses on the physical processes and dynamics of the atmosphere at a very small scale and over short time periods (minutes to days). Microclimatology is a broader term often concerned with the description and causes of persistent local climate conditions (over seasons or years), though there is significant overlap and the terms are sometimes used interchangeably.

Primarily atmospheric scientists, environmental researchers, agronomists, and some specialists in urban planning, forestry, and renewable energy. It is not a word used by the general public or in everyday weather forecasts.

Yes. The formation of a ground frost on a clear, calm night in a valley bottom, while the surrounding hillsides remain frost-free, is a classic micrometeorological phenomenon driven by cold air drainage and radiative cooling at a very local scale.

Yes. While standard weather stations measure general parameters (temperature, humidity, wind speed/direction), micrometeorological studies often require high-frequency sensors (like sonic anemometers) to capture turbulent eddies, and instruments placed at very specific heights and locations to measure vertical gradients and fluxes (e.g., of heat, water vapour, or CO2).

The branch of meteorology that deals with atmospheric phenomena and processes on a very small scale, typically over distances of less than one kilometre.

Micrometeorology is usually scientific/technical in register.
