Summary

Summary

  • April 2007 was an extremely bad month with almost half the number of sailing days than usual

  • Analysis has been done with the best available data and would stand up to independent scrutiny

  • Suitability of Valencia as a sailing venue should not be judged on one extremely rare meteorological event


What makes wind in valencia

What makes wind in Valencia?

  • Gradient Vs Sea breeze

  • Need favorable gradient wind for sea breeze

    • Southerly gradient gives the strongest sea breeze

    • North-easterly gradient gives weakest sea breeze

  • Thermal effect, especially over the mountains

    • Warm over land, cool over sea


Atmospheric block

Atmospheric ‘block’

  • Occurs mainly over Europe in the winter and spring

  • Stable pattern – hard to break

  • Position can change

    • It makes a significant difference to the weather

  • Very hard to predict when the ‘blocks’ form and when they will disappear!
