Description: Climatology data | Version: 4.9.0 | Updated: 10.03.09 | |

An arbitrary number of header lines can be added at the top of the file. WindSim interprets particular keywords terminated with a colon in column 20. Some of the keywords are followed by mandatory input, others are optional.
After the header information, follows the scaled frequency distribution grouped according to wind direction and speed. The distribution is scaled to unity, meaning that frequency distribution sums up to give 1. An arbitrary number of wind directions or sectors can be used. Sector 1 is centred around 0 °, and the following sectors are equally distributed. The speed intervals are given with both minimum and maximum limits, allowing an unequal distribution. There are maximum limits for the number of sectors and speed intervals, these limits might vary in different WindSim versions, see the Tools->WindSim limits menu item.
