If X is an instance of water wave and The waveHeight of X Y., then there exist Z, W,, , V and U such that Y is a member of Z and W is an instance of water area and X is located at W and V is an instance of unit of length and significantWaveHeight in W during the time of existence of X is U V(s). and equal U and 4.0 and The StandardDeviationFn of Z
