Radar Migration September 1, 2016

Posted on Sep 1, 2016

Happy September! Kick yours off with a great day of birding tomorrow and hopefully Saturday as the birds head out on the northerly flow behind the finally departed front. Once we get to Sunday the weather gets intriguing with Tropical Storm Hermine making a run to the Northeast and likely impacting conditions throughout the region. Remember that when looking at this radar capture the darker the blue, the more birds in the air. Green is even more intense and heavy migration. The birds appear to be basically centered around radar stations because the radar beam rises through the atmosphere as it leaves the origin and captures anything aloft mostly in a circular area surrounding it. In reality we can surmise the birds fill the sky essentially – some may be just above or then below and out of reach of the beam. The intensity can still be helpful to note which areas have the most and the direction they appear to be moving when watching multiple frames.
