Valley winds, sunny faces and convergence

0 viewsOct 7, 2026

How the mountains work through the day: slopes that face the sun, valley winds and convergence, with the Enns valley as the example. And the landable fields you plan the flight around.

What you learn

  • Pick the slope the sun is working on at each time of day
  • Use the valley wind, and spot the slopes it makes work
  • Find convergence where two flows meet over a range
  • Plan the flight from field to field with a 20:1 margin
