I will simulate the ash dispersal from Eyjafjallajokull using HYSPLIT. By simulating the ash dispersal during different times in the year I hope to determine the ash dispersal variation given different atmospheric circulation patterns.

HYSPLIT Simulations for Eyjafjallajokull (Varying Eruption Date)
April 14-16, 2010
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 and then towards the south-west. From the initial movement, we can see the westerlies that define the mid-latitude regions. The two layers closest to the Earth's surface spread the furthest.
