Short Description of Functionality
The program LZKAF computes several characteristic numbers out of wind data as well as wave data. The data must be given as time-series (in universal direct access data format). The results of LZKAF may be visualised/displayed with the graphical postprocessor HVIEW2D.
Within the period of data analysis the following characteristic numbers can be (optionally) calculated:
- Analysis of wind speed time series data:
- Analysis of significant wave height time series data:
Input-Files
- general input data (filetype lzkaf.dat)
- time series of meteorological data (files of type dirz.bin.r, dirz.bin.i, and dirz.bin)
- grid for 2D/3D-data (filetype gitter05.dat/bin)
Output-Files
- results of data analyses for the overall domain (files of type dirz.bin.R, dirz.bin.I, and dirz.bin)
- results of data analyses for sectors (files of type dirz.bin.R, dirz.bin.I, and dirz.bin)
- informative printer file (filetype Lzkaf.sdr)
- (optional) trace of program execution (filetype Lzkaf.trc)
Methodology
This program is able to generate statistics for wind speed as well as wave height time series data. LZKAF determines the frequency distribution of wind velocity or wave height for different intervals of wind velocity / wave height and different directional sectors of wind / wave direction. The number of intervals and directional sectors as well as the value of their upper and lower limits can be defined by the user.
Beyond that, additional characteristic numbers, indedependant of direction (e.g. time of occurrence, maxmimum values, duration of high values, ...) can be computed too.
