| Abstract | Cut-of Low (COLs) are often associated with heavy precipitation and strong wind events, but there are still uncertainties on how their identifcation afect the numbers and seasonality. This paper aims to determine the sensitivity of identifying Southern Hemisphere COLs in the ERA-Interim reanalysis to diferent types of identifcation criteria. Upper-level cyclones are initially tracked on the 300 hPa level using relative vorticity and geopotential in order to present diferent perspectives. This reveals signifcant diferences between the numbers and length of the identifed tracks for the two felds. To identify the COLs diferent post-tracking flters are applied which are divided into two steps. Firstly, three flters are considered to separate cut-of lows from open troughs by sampling winds at diferent ofset radial distances from the upper-level cyclonic centres. Secondly, potential vorticity and temperature criteria are imposed to determine how these conditions afect the identifed COLs in terms of numbers, seasonality and intensity. It was found that methods based on multiple criteria restrict the COL identifcation by imposing specifc characteristics, while methods based on simpler schemes (e.g. using only winds) can detect larger samples of COLs observed visually in the geopotential maps. Although it is difcult to say which method is more accurate in identifying COLs, because of the subjective aspect of observers assessment, a scheme using only winds should be more representative of reality as this simply imposes on the detection system a cyclonic circulation appearance regardless of the physical and dynamical characteristics. Therefore, this type of method could be considered as a standard method for identifying COLs that can be used for either operational or research purposes. |
