In studying a synoptic chart,in addition to the main isobarformation, there are other minorfigures delineated. These are,secondary cyclones, V-shaped de-pressions, wedges, cols, and straightisobars. Secondary Cyclones are in-complete cyclones, in which theisobars form only portions of acircle or oval. They are areas oflow pressure, the lowest pressures, as in cyclones, being at the centre, while their movement also resembles that of cyclones. \-shaped Depressions often form the angular interval between adjacent anticyclones, and often have their low pressure in the interior of the V.
