A large volcano recently erupted in Iceland and repercussions are being felt throughout much of Europe. The ash is so thick in much of Europe that many flights have been canceled. More cancellations are likely since there is little end in sight. The volcano continues to send plumes of ash high in the atmosphere and is likely to do so for the next few weeks or longer. At this point the main impact is economic due to the travel problems. Much of Europe is feeling the impact of the volcanic since the upper level winds carrying the ash is from northwest to southeast. The trajectory of the wind flow is likely to persist for the next two days. Eventually, ash is expected to spread all the way from the North Pole to the Equator, although it will not be nearly as thick as it is now. We could see some beautiful sunrises and sunsets later in the spring and summer as a result of the ash particles and their reflection from the sun.
