The importance of convective gusts

Surface wind measurements in three Gulf Coast hurricanes of 2005

“…It has been suggested that organized storm features aloft can contribute to or possibly modulate surface level wind characteristics owing to their convective nature (Bradbury et al, 1994;Wurman and Winslow, 1998). Based on 15-min turbulence intensities for each of the towers that experienced an eyewall passage, it appears that the turbulence intensities were not affected by the passage of the hurricane eye.…”

A comparative study of field measurements of the turbulence characteristics of typhoon and hurricane winds

“…As upper level disturbances descend downwards, sudden changes in the wind speed and direction along the radial axis of the storm are experienced at the ground level. The downward transport of convective elements and horizontal momentum in higher level by downdraughts and boundary layer rolls also magnifies the wind speed and the variance of fluctuations in the surface (Powell et al, 1991Bradbury et al, 1994;Wurman and Winslow, 1998;Sparks and Huang, 2001;Vickery and Skerlj, 2005;Li et al, 2012aLi et al, , 2014. In light of the dominant features that are different from the extratropical storms, there is a need for better understanding of the turbulent wind characteristics and the flow structure in tropical cyclones.…”

Convective and non-convective wind gusts in Poland, 2001-2015

“…Therefore, in this study the authors decided to use only 9 stations, which are quite evenly spaced over polish territory and represent similar measuring conditions. additionally, wind gust occurrence was analysed separately for the convective and non-convective generative types, which involve different mechanisms that shape the dynamics of these phenomena (Bradbury et al 1994;nakamura et al 1996;Brasseur 2001;Jungo et al 2002;Hofherr, kunz 2010;smith et al 2012).…”
