The representation of temperature, moisture, pressure, and wind variations on horizontal scales of 10–100 km. The analysis seeks to define mesoscale features of the observed temperature, pressure, moisture, and wind fields that can be related to important local and regional circulations that in turn may have a significant impact on local and regional weather systems. The mesoanalysis differs from the more conventional synoptic-scale representation of the wind and pressure features in that smaller- scale features inherent in the wind, pressure, and moisture fields are retained in the analysis.
