Cover Story: On 23/12/2009, windstorm Xola hit mainland Portugal, and brought damaging winds. Xola featured a prominent cloud head and a split cold front structure. Radar observations revealed banding and other features consistent with slantwise convection in the cloud head tip. At the tip end, a low-level jet streak was identified with maximum Doppler winds exceeding 55 ms−1 at just 400 m height, reflecting the presence of a Sting Jet. In southern mainland Portugal, the downburst winds, associated with a mesovortex, caused extensive damages in power towers. This mesovortex was embedded in a bow echo line, triggered by an upper cold front. View this paper
