“…Snow et al (1980) used laboratory pressure measurements as an additional method of inferring the continuum of swirlratio-dependent vortex structures (Fig. 2) More recent laboratory simulations of tornado-like vortices examined the pressure and force distribution on the individual faces of a cubical model (e.g., Mishra et al 2008;Sengupta et al 2008). These studies indicate that wind loads produced by tornadoes greatly exceed the Snow et al (1980) and Church and Snow (1993). loads produced by equivalent straight-line boundary layer wind profiles, including those of microbursts.…”

“…Actually, the evolutionary spectral (EvSp) analysis may be understood as a natural extension of the spectral analysis, since the former approach should necessarily tend to the latter one over large timescales, provided the intensity envelope remains constant in time. The evolutionary approach remains an elegant formulation of transient phenomena, for which evolutionary models are available, as for earthquakes or downbursts [68,33,10,11,56,73]. However, it requires to work in both time and frequency domains, contrary to the classical spectral analysis.…”

“…According to [33], such an event normally occurs during thunderstorms. Some pertinent theories have been developed in the last decade to apply more realistic models of transient wind velocity [68,11,56,73]. For downbursts, Holmes et al [33] propose an empirical model based on the translation velocity of the storm and the radial velocity of the air [10].…”

“…The effect of straight line winds on structures has been studied extensively and has led to the development of the current design provisions [14]. However, research has been less robust in terms of understanding the effects of tornadoes on structures with only a limited number of studies conducted on this topic [13,[15][16][17]. Many of these studies present a combination of theoretical and experimental work with the main purpose of comparing the effects of tornadoes versus straight line winds.…”
