deepening"A decrease in the central pressure of a pressure system as depicted on a constant- height chart, or an analogous decrease in height on a constant-pressure chart; the opposite of filling.
DEEPENING Used in describing the history of a low pressure system or an area of cyclonic circulation, it means a decrease in the central pressure of the system.
Deepening
A decrease in the central pressure of a surface low pressure system. The storm is intensifying.

DEEPENING- The intensification of a low pressure system (in particular the lowering of central surface pressure).
deepening—A decrease in the central pressure of a pressure system; usually applied to a low rather than to a high, although technically, it is acceptable in either sense.
Rapid Deepening: A decrease in the minimum sea-level pressure of a tropical cyclone of 1.75 mb/hr or 42 mb for 24 hours.
Deepening: In synoptic meteorology, it means to reduce the pressure in the center of a cyclone in time.
Dew: Water droplets condensed over the grass or any other surface next to the soil.
DEEPENING - Term applied to the pressure drop associated with an intensifying low pressure system.
DPNG - Deepening. Usually in reference to a low pressure intensifying.
RAOBRadiosonde Observation (Upper-Air Observation)Rapid DeepeningA decrease in the minimum sea-level pressure of a tropical cyclone of 1.
Simultaneously, the deepening of the winter upper-level trough (typically found over the eastern US) produced heavier than normal rains in the southern states (blue shading).
ChannelizationIn hydrologic terms, the modification of a natural river channel; may include deepening, widening, or straightening.
Fill DamIn hydrologic terms, any dam constructed of excavated natural materials or of industrial wastesFillingThe opposite of deepening. A general increase in the central pressure of a low pressure system.
Filling An increase in the central pressure of a pressure system; opposite of a deepening. More commonly applied to a low rather than a high.
The storm begins as a tropical depression, as anticlockwise circulation begins to develop around a rainy, deepening low-pressure area. When the winds exceed 33 kt, the tropical depression is promoted to tropical storm and is given a name.
Intensification or "deepening" of the extratropical cyclone progresses slowly. Often, the sea-level pressure in the low-pressure cell fails to drop below 1000 millibars (1000 hectopascals) (hPa) (SI).
Channelization The modification of a natural river channel; may include deepening, widening, or straightening.
Dart Leader: An electrical charged ionized channel which dart from the thunderstorm cloud to the
ground after the Stepped Leader has estabilished contact with the ground.
Deepening:When the central pressure of a cyclone drops.

entrainment rate - The rate at which entrainment proceeds. In the absence of advection effects, the entrainment rate is equal to the rate of deepening of the mixed layer.
However, over warm tropical Atlantic waters they often become intensified by latent heat. If there is enough 'fuel', i.e. sea surface water warmer then 26°C, the trough will be deepening becoming more organized forming a tropical storm and maybe a ...
Although it usually describes the action of a pressure system on a constant pressure chart, it also means a surface low is decreasing in cyclonic circulation and losing its characteristics. The opposite of deepening.
