Abstract: Over the past two decades, wind engineering has focused on non-synoptic wind storms, which exhibit greater spatio-temporal complexity than synoptic scale winds. Here we focus on the modelling of downburst velocity fields in relation to the way these models can be used to determine structural responses to downburst winds. Two approaches have been defined in relation to the Main Wind Force Resisting Systems (MWFRS): (i) the Gust Front Factor (GFF) from Professor Ashan Kareem’s group at Notre Dame University in USA and (ii) the Thunderstorm Response Spectrum Technique (TRST) from the late Professor Giovanni Solari’s team at the University of Genova in Italy. Both methods decompose the downburst mean wind field into a vertical profile and a time variation. Here we focus on the modelling of downburst velocity fields in terms of spatial and time characterizations including the effects of translation, atmospheric boundary layer (ABL) superposition and surface effects.
