  1. Middle Latitudes - 30°to 60° Sublime… …ridiculous but why is it so changeable?

  2. Sea Surface Temperatures – January (2008) NH Ice Limits 60 N 30 N

  3. www.youtube.com/watch?v=jup-5Xu1OOU Middle latitudes have interesting weather patterns but are very unpredictable. Making navigation and operations challenging!

  4. How do we predict and plan for weather changes? Jet Stream Warmer Colder Area Area http://www.metoffice.gov.uk/public/weather/marine

  11. Ships use forecasts to determine the most appropriate routes.

  12. Good forecasting and planning allows us to execute the safest and most efficient operations in a naturally dangerous environment. http://www.uk.endress.com/
