Niwa scientists have found the Auckland Harbour Bridge itself helped increase wind speeds to a point at that trucks toppled over. Niwa scientists now want to look at whether wind breaks erected on the sides of some bridges overseas would be helpful. Photo: Supplied/ NZTA Part of the bridge had to be closed for repairs for more than two weeks after two trucks fell over in high winds in 2020. The wind gust measured 127km/h at the top of the bridge arch. At the time, Niwa scientists had been operating a weather forecasting model known as the Auckland Model to predict wind shifts in the Hauraki Gulf, so scientists Drs Richard Turner and Stuart Moore and modeller Amir Pirooz wondered how accurately it could also have predicted the high winds on the bridge. ....
Tuesday, 27 April 2021, 9:30 am When high winds on the Auckland Harbour Bridge last September caused two trucks to topple over, one into a load-bearing strut, NIWA scientists began thinking about what role they could play in preventing it from happening again. The incidents were described at the time as being caused by a freak wind gust of about 127km/h measured at the top of the bridge arch, and meant some of the bridge lanes had to be closed for more than two weeks for repairs, resulting in long delays for motorists At the time, NIWA scientists had been operating a high-resolution weather ....
Coincidentally, scientists at the National Institute of Water and Atmospheric Research (NIWA) had been developing a computer model of wind patterns in the harbour as part of Team New Zealand s preparation for their defence of yachting trophy the America s Cup. They combined this Auckland Model with a three-dimensional model of the bridge, looking at how air moves around it - and found the bridge itself causes the wind to speed up. The modelling found speeds at road level and between the struts - one of which was damaged and had to be replaced - are 10 to 15 percent faster than the surrounding wind. While the modelling correctly identified the timing and direction of the gusts that September morning, it actually underestimated just how much faster the wind would get as it hit the bridge. ....
