Naud, C.M., J.E. Martin, P. Ghosh, G.S. Elsaesser, and D.J. Posselt, 2023: Automated identification of occluded sectors in midlatitude cyclones: Method and some climatological applications. Q. J. Roy. Meteorol. Soc., 149, no. 754, 1990-2010, doi:10.1002/qj.4491.

A novel automated scheme for identifying occluded mid-latitude cyclones from gridded data sets is described and employed to construct a limited climatology of such storms as well as composites of their thermodynamic and kinematic structures. The climatology (2006-2017) is derived from the MERRA-2 reanalysis and reveals differences in the distribution of occlusions between the hemispheres. Northern Hemisphere occlusions are most frequent in winter (DJF) and are found poleward of the mean tropopause-level jets in both the Atlantic and Pacific basins. In the Southern Hemisphere, however, occlusions are most frequent during autumn (MAM) and are almost never found equatorward of 40°S.
