PRESSURE TENDENCY The pressure characteristic and amount of pressure change during a specified time period, usually the three hour period preceding the observation.
PRESSURE TENDENCY: (BAROMETRIC TENDENCY) The change in barometric pressure within a specified period of time (typically 3 hours for meteorological observations).
pressure tendency—See barometric tendency.
prevailing easterlies—The broad current or pattern of persistent easterly winds in the Tropics and in polar regions.
