*WIND2

Data format:

An arbitrary number of lines with up to 19 values each.
Lines may be continued using the & character

TWIND(1) TETC(1,1),VWIND(1,1) TETC(1,NZWIND),(VWIND(1,NZWIND) ... TWIND(NTWIND) TETC(NTWIND,1),VWIND(NTWIND,1) TETC(NTWIND,NZWIND),VWIND(NTWIND,NZWIND)

Status : Optional

Purpose : Defines a time dependent WIND profile with variable heading

Limitations : If keyword *WINDLEVEL does not precede this one, NZWIND will be assumed to be equal to 1 so the WIND is constant down the whole depth of water. |

Details :

Parameter	Description
TWIND(i)	Time
TETC(i,j)	WIND heading at time TWIND(i) and level ZWIND(j) in degrees from the positive x-direction (anticlockwise is positive)
VWIND(i,j)	WIND speed at level ZWIND(j) and time TWIND(i)
NTWIND	Number of given times (Max. is 20)

Note

TWIND(i) must be given in increasing order
TWIND(1) must be equal to 0
If NTWIND is equal to 1, the WIND is time independent
The WIND is linearly interpolated in time, depth and heading
If necessary the EOL symbol & may be used to write the values on several lines.

Examples :

a)

*WIND2
0 &
180 1.34 180 0.9 180 0.69 180 0.62 180 0.49

The WIND is heading at 180 degrees, opposite to the x-direction and decreases with depth but is constant in time

b)

*WIND2
0. &
180 1.34 180 0.9 180 0.69 180 0.62 180 .49 &
10. 170 1.34 170 0.9 170 0.69 170 0.62 170 .49 &
20. 160 1.34 160 0.9 160 0.69 160 0.62 160 .49

The WIND is a non uniform WIND changing its heading with time.
