“…These findings are consistent with previous studies and reports. As discussed in the Introduction, three studies of such events have been carried out over this region [2,23,24]. In all of these, storms producing the adhering solid precipitation tracked to the right of locations, and always to their south and/or east, and consequently produced northerly and/or easterly winds.…”

“…In addition, as evidenced in Figures 10 and 11, directions of these winds often have a northerly or northeasterly component. For perspective, [2] found that the strongest and northerly winds occurred after 20 h of continuous adhering solid precipitation within one very damaging event over…”

“…Many of these impacts are directly related to the associated precipitation, which can vary among, for example, snow, freezing rain, and ice pellets [1]. A particular type of hazardous winter storm produces snow that adheres to surfaces, especially with strong winds [2]. The build-up of snow enhances the weight and drag experienced by structures and vegetation.…”

“…[24] examined several storms that produced adhering snow over Manitoba and pointed out the importance of the region's small topographic features on its spatial distribution. [2] examined an October 2019 event over Manitoba that led to unparalleled damage to electrical utility infrastructure and, in some areas, to more tree damage than from any previously recorded event.…”

“…Consequently, the objective of this study is to examine changes in adhering solid precipitation over this region's land areas in a warmer climate. Note that some events with adhering snow also produce snow pellets and ice pellets at near 0 • C temperatures [2], although, if they occur, these latter precipitation types are usually present in small amounts. Nonetheless, and following [28], the term 'adhering solid precipitation' will be used to cover all these types.…”

Solid precipitation falling near 0 °C, mainly snow, can adhere to surface features and produce major impacts. This study is concerned with characterizing this precipitation over the Canadian Prairie provinces of Manitoba and Saskatchewan in the current (2000–2013) and pseudo-global warming future climate, with an average 5.9 °C temperature increase, through the use of high resolution (4 km) model simulations. On average, simulations in the current climate suggest that this precipitation occurs within 11 events per year, lasting 33.6 h in total and producing 27.5 mm melted equivalent, but there are wide spatial variations that are partly due to enhancements arising from its relatively low terrain. Within the warmer climate, average values generally increase, and spatial patterns shift somewhat. This precipitation consists of four categories covering its occurrence just below and just above a wet-bulb temperature of 0 °C, and with or without liquid precipitation. It generally peaks in March or April, as well as in October, and these peaks move towards mid-winter by approximately one month within the warmer climate. Storms producing this precipitation generally produce winds with a northerly component during or shortly after the precipitation; these winds contribute to further damage. Overall, this study has determined the features of and expected changes to adhering precipitation across this region.
