- Abstract
Integrated water vapour transport (IVT) from 1000 to 300hPa in the North Atlantic region 1200 utc 21 September 2021 obtained from a Weather Research and Forecasting (WRF) model run initialised with Global Forecast System (GFS) operational analysis data showing an "atmospheric river" associated with an explosively deepening cyclone which produced extreme winds over Iceland. In this particular case, features of a sting jet cyclone can be identified in satellite imagery around the time of the extreme wind gusts recorded over Iceland (Figures 2 and 3). According to local sources,[1] it was the deepest low pressure system to traverse Iceland during September since 2004.
