SUB-SYNOPTIC LOW- A relative small area of surface low pressure. They are also referred to as mesolows.
Sub-synoptic Low - Essentially the same as mesolow.
Suction Vortex (sometimes Suction Spot) - A small but very intense vortex within a tornado circulation. Several suction vortices typically are present in a multiple-vortex tornado.

Synoptic Chart: Chart or map in which selected meteorological elements are represented over a large region at a given moment.
Synoptic scale
A scale of distance used by meteorologists to describe large weather disturbances. Weather systems which span thousands to millions of square miles and which exist for several days are on the "synoptic scale".

A synoptic-scale cloud pattern with a characteristic comma-like shape, often seen on satellite photographs associated with large, intense low-pressure systems.
Comma echo ...
In synoptic meteorology and in weather observing, that portion of the atmosphere that is above the lower troposphere. No distinct lower limit is set but the term can be generally applied to the levels above 850 mb.
Vertical Wind Speed ...
For synoptic and climatological work therefore, a 'standard' exposure is required. That standard is for the wind speed and direction over a level surface to be measured at a height of 10 m above ground level (agl).
(or Sub-synoptic Low) A mesoscale low-pressure centre. Severe weather potential often increases in the area near and just ahead of a mesolow.
Mesolow should not be confused with mesocyclone, which is a storm-scale phenomenon.
