Mean of the daily minimum temperatures observed during a specific calendar month, either for a specific year or over a specific period of years.
Industry:Weather
Mean of the temperatures observed at 24 equidistant times in the course of a continuous 24-hour period (normally the mean solar day from midnight to midnight according to the zonal time of the station).
Industry:Weather
Any chart on which isopleths of the mean value of a given meteorological element are drawn. Compare normal chart.
Industry:Weather
Mean of the daily maximum temperatures observed during a specific calendar month, either for a specific year or over a specific period of years.
Industry:Weather
The difference between the mean temperatures of the warmest and coldest months of the year.
Industry:Weather
The topography of the surface of maximum wind speed. The contours of maximum-wind height form one of the sets of lines on an analyzed maximum- wind and shear chart. See maximum-wind level.

Industry:Weather
An arithmetic average. Types can include mean over an ensemble of experimental realizations, mean over a time period, mean along a line such as a road or flight path, mean in an area such as a farm field, or mean within a volume of air such as can be sampled by a remote sensor. For example, the mean wind speed from anemometer measurements is the speed at a fixed point averaged over a time period such as 10 minutes.
Industry:Weather
The height at which the maximum wind speed occurs, typically within the jet stream, determined in a winds-aloft observation. See maximum-wind and shear chart.
Industry:Weather
A synoptic chart on which are plotted the altitudes of the maximum wind speed, the maximum wind velocity (wind direction optional), plus the velocity of the wind at mandatory levels both above and below the level of maximum wind. These maps can be analyzed for one or more of the quantities plotted.
