Tropical Cyclone (TC) Ita (2014) was a major storm that affected coastal areas of Northeast Queensland. Topographic features along the coastline are known to modify the structure and intensity of such events. This study utilises the Advanced Research version of the Weather Research and Forecasting (WRF-ARW) model to investigate topographic influences during the landfall phase of TC Ita. While the removal of topography over the whole domain steers the modelled TC far away from the landfall point, removing topography from only a smaller area allowed an investigation of the topographic influence on near-surface wind conditions in that area. Flow over the region of removed topography exhibit smaller inland velocity gradients for winds flowing onshore and a sharper acceleration of winds as they moved offshore.
