Wind power is the predominant new renewable source of power. Due to the growth in the height of the turbines, recent studies pointed out that the logarithmic law describing the vertical wind profile presents limitations. At the same time, the success of wind power means that wind turbines are increasingly put in sites with complex terrain and offshore. Integration of large amounts of wind energy into the grid is another current challenge. Therefore, we propose the following list of topics:

* Wind conditions (both resources and loads) on short and long time scales for wind power development.

* Wind conditions in complex terrain (mountains, forests and coastal).

* Forecasts of wind power for the next minutes or next days, in general and for extreme events.

* Wake effects, especially for large wind farms and offshore.

* Effects of large-scale integration.

* Local, regional and global impacts of wind farms.

* Dedicated wind measurement techniques (SODARS, LIDARS, UAVs etc.).
