Severe convective wind potential for Australia from 1979-2023

This collection contains the historical baseline data for severe \nconvective wind potential from 1979-2023. The data is derived from \nBARRA-R2 reanalysis which has a horizontal resolution of \napproximately 12km. The yearly values are for [1979, 2023].\nLineage: Severe convective wind events are associated with three different \ntypes:\n* strong background winds\n* steep lapse rate\n* high moisture environment\n\nFrom these three types, Brown and Dowdy (2023) found that first \noccurs more frequently during the austral winter while the second \nand third occur more frequently during the austral summer. They \nalso found that all three events are more likely to occur \nbetween 12noon and 6pm.\n\nThis directory contains data on number of days in a year with \nTotal totals in three different ranges.\n\n* Total totals [45, 50) : Thunderstorms possible\n* Total totals [50, 55) : Thunderstorms most likely, possibly severe\n* Total totals [55, 60) : Severe thunderstorms most likely.\n\nTotal totals is one of many indicators used to identify the potential of \nthunderstorm activity. In their recent publications, Brown and Dowdy (2023) have \ndeveloped a more complicated indicator using logistic regression, however, \nhere, Total totals is used, as this relatively simple indicator, and \nperforms quite well (see Brown, A. and Dowdy, A. (2023): https://doi.org/10.1071/ES19052).
