Severe hailstorms can cause extensive <\/span>economic<\/b> damage to both crops and properties. Report<\/a> by<\/span> Munich RE<\/b>\u00a0<\/b>shows that damage of individual events can exceed billions of dollars as the risk has increased in the past decades. Hail damage to properties, such as cars, roofs and windows, becomes substantial when the diameter of hailstones approaches and exceeds 5 cm. Each year there are a number of such events when hail of this size occurs across Europe and this year, 2018, was no exception.<\/span><\/p>\n

By looking at the ESWD dataset, we found <\/span>26 days<\/b>, when hail exceeded <\/span>5 cm<\/b> and caused significant damage<\/strong> to the properties. The spatial distributions of these major hail events and associated hail sizes can be found in <\/span>in Fig. 1<\/em><\/b>.<\/em> The largest hail size was observed on <\/span>8 June 2018<\/b>, when the town of \u010crnomelj<\/strong>, Slovenia<\/strong> was hit by giant hail up to <\/span>12 cm<\/b> in diameter, destroying hundreds of roofs and cars. The hail swath on that day (<\/span>40 km<\/b>) was much shorter compared to long-lived hailstorms of <\/span>1 May<\/b> in <\/span>Poland<\/b> (<\/span>220 km<\/b>) or the hailstorm of <\/span>30 June<\/b> in <\/span>southern Russia<\/b> (<\/span>200 km<\/b>). <\/span><\/p>\n

These damaging hailstorms occurred in an environment of moderate to <\/span>high CAPE<\/b> and <\/span>bulk 0\u20136 km wind shear exceeding 15 m\/s<\/b>, conditions which favour strong updrafts and well-organized convection, including supercells. <\/span>Our research<\/span><\/a> shows that such conditions may become <\/span>more frequent in the future<\/b>. As we compare with the sounding database developed by <\/span>Pucik et al (2015)<\/span><\/a>, most of these events occurred in typical conditions for damaging hailstorms (Fig. 2<\/em><\/strong>)<\/span>.<\/b> Several of these events formed in rather <\/span>weak<\/b> vertical wind shear (<\/span>i.e., bulk 0-6 km shear ranging from 10 to 15 m\/s<\/b>) but these cases were confined to the proximity of complex orography, where shear could be strongly enhanced locally. <\/span><\/p>\n
