I was looking at the NOAA hysplit model – this is a model that can backtrack the route an airmass came from. I chose to look at the 14th December as this brought strong winds to the UK and a rapid temp drop. At 1,500 metres the air comes from Baffin Island. At 500 metres the air comes from fram strait (between Greenland and Svalbard) At 100 metres the air comes from near Nuuk. Why is this air split up like this coming from different locations far apart? submitted by /u/Some-Air1274 |
