Relating 3 variables in a probability problem

[volantis]

Hey guys, I have a minor problem of combining three related variables in a probability problem. I have tables (probability (%) of occurrences) for wave period and wave height, as well as wave height and wave direction:

			Period (s)
		8	11	14	17
	1	0	4.950879271	0	0
Height (m)	1.5	9.85682482	26.46800515	21.5375503	2.851248953
	2	3.517085027	8.020669512	17.04009314	2.424378587
	2.5	0	0	3.333265252	0

			Height (m)
		1	1.5	2	2.5
	N	0	3.243623218	1.126732276	0
	NNE	0	0	0	0
	NE	0	0	0	0
	ENE	0	0	0	0
	E	0	0	0	0
	ESE	0	0	0	0
Direction	SE	0	0	0	0
	SSE	0	0	0	0
	S	0	5.497087769	2.187186182	0
	SSW	2.118899377	18.41534445	7.903193412	0
	SW	0	3.874271942	1.353685479	0
	WSW	0	2.197228359	0	0
	W	0	2.084755975	0	0
	WNW	0	3.856196023	1.683068889	0
	NW	1.681060454	10.83751757	8.063868247	1.903996787
	NNW	1.45410725	11.22514561	7.527615987	1.765414742

My problem is: I need to obtain the directional probability of occurrence with respect to the wave period.
E.g. I need to know how much (percentage) of the SSW direction, for each listed wave height occurs at each wave period, so that I can then calculate the frequency of waves in each direction over an entire year.
If someone could help me relate the variables it would be greatly appreciated. Let me know if you need additional clarification to the problem.

Cheers
