Short Description of Functionality

A time series of physical vector data (amount and direction) will be analysed to get the relative frequencies of occurrences. These frequencies of occurrences will be plotted in a wind rose diagram.
Example Wind data in 2001, measured at isle Borkum visualization of frequencies of occurrences of wind data measured at isle Borkum in 2001. The frequencies of wind velocities will be separated to 16 direction classes (north (N), north-north-east (NNO), north-east (NO), ...) The wind velocity classes are colour coded: blue colours represent low wind velocities, green colours mid wind velocities and red colours high wind velocities. All wind velocity classes together are mapping the Beaufort scale. The analysis of the time series is divided into 4 phases each lasting 3 month: January to march, april to june, july to september and october to december.

Input-Files

1. General input file (file type rose.dat)
2. Time series of the physical vector data (amount and direction) (file type boewrt.dat)
3. Layout information (file type format.lay)

Output-Files

1. graphical output to the screen
2. plot metafile(s) (GKSM or CGM) and scale info file(s) (rose???.gksm.scale or rose???.cgm.scale) for later calculation of geo-referenced coordinates
3. GKS-Logfile (filetype gkslog.dat)

Notice: This file is used to record all interactive user input for a complete ROSE application run. This file can be used at a later stage to rerun the whole session in exactly the same way.

Methodology

• Step 1: Selection of the physical vector data
• Step 2: Reading of the time series
• Step 3: Selection of the time window inside the time series
• Step 4: Computation of the relative frequencies of occurrences
• Step 5: Visualization of the relative frequencies
