Image 3: 3-day ash dispersal simulation for Eyjafjallajokull for actual eruption date of April 14, 2010. The plume initially moves towards the north-east eastward and then towards the south-west. From the initial movement, we can see the westerlies that define the mid-latitude regions. The westard.
