“…The tracking algorithm described by Hodges (1994) was applied using a methodology based on Hodges et al (2017), who use TRACK to identify tropical cyclones, as well as their antecedent and subsequent phases as tropical lows and tropical depressions. This was deemed appropriate since the southern African tropical lows are similar in spatial extent and magnitude to tropical lows which transition into and out from tropical cyclones.…”

“…In the initial phase of tracking, these minima were linked together using a nearest neighbor method. The accuracy and realism of the tracks are then improved using an optimization scheme which minimizes a cost function of displacement distance and track smoothness based on adaptive constraints following the methodology of Hodges (1999).…”

“…In the intervening years, various tools have been developed to identify and follow atmospheric features in reanalysis data sets as they evolve and move through space. One such tool is Maidment et al (2017) TRACK, which was developed to study extratropical storms tracks (Hodges, 1994(Hodges, , 1999 and has since been applied to tropical cyclones (Hodges et al, 2017) and tropical lows (Hurley & Boos, 2015). Hurley and Boos (2015) found that around 12.5 tropical lows formed each year in southern Africa, but their globally based approach did not provide detail on the nature of tropical lows over southern Africa.…”

Tropical Lows in Southern Africa: Tracks, Rainfall Contributions, and the Role of ENSO

Southern African tropical lows are synoptic‐scale cyclonic vortices that propagate westward across southern Africa in the Austral summer. They strongly influence local rainfall and aggregate in the climatological December, January, and February mean to form the Angola Low. In this study, tropical lows are identified and tracked using an objective feature tracking method. The statistics of tropical low tracks over southern Africa are presented and compared across three reanalysis products. Findings are compared to the literature of tropical low‐pressure areas elsewhere in the world, where it is found that most tracking statistics compare well but that the tendency of tropical lows to become semistationary over Angola is unique to southern Africa. The hypothesis that tropical lows in Angola have a causal relationship with Tropical Temperate Troughs is tested, and a correlation between occurrence frequencies is found at interannual but not daily time scales. Precipitation is attributed to the tropical lows, and it is found that tropical lows are associated with 31% of rainfall across tropical southern Africa, based on gridded precipitation products. The interannual variability of the number of tropical lows that form per year (σ=6 events/year) is linked to El Niño–Southern Oscillation (ENSO) and the tropical easterly jet. The mean latitude of tropical lows is shifted northward during El Niño and southward during La Niña. Much of the interannual precipitation variability maximum in Angola is attributed to rainfall associated with tropical lows. These results provide insights into the southern African response to ENSO and into the mechanisms of rainfall in the southern African tropical edge.

Anshan (Anzan/Anšan) is a geographic name that appears most commonly in the titulary of the Middle Elamite kings – “kings of Susa and Anshan.” Rulers of the early Sukkalmah period also occasionally refer to themselves as kings of Anshan and Susa. Anshan (modern Tal‐e Malyan) was identified on the basis of numerous inscribed brick fragments of king Huteludush Inshushinak (1125–1104 bce ) found on the mound. It lies 500 kilometers southeast of Susa in an upland internal drainage basin of the central Zagros range in the Kur River Basin of Fars Province, Iran. Excavations and survey revealed occupations of the mound in the late fourth through early second millennia bce and during the last centuries of the second millennium bce , the late Middle Elamite period.
