Figure 14. Predicted horizontal-temperature-gradient field model. Horizontal-temperature-gradient 

 contour values are in °C/ft. Horizontal -temperature- gradient contours repeat every A/2 from zero to 

 n wavelengths throughout the model. 



in the wavelength, probably because of the modal distribution of 

 the internal waves. In general, the simplified model provides a 

 valid description of the horizontal -temperature gradients. 



Although the simplified model offers only the order of 

 magnitude of the temperature gradients and the wavelength is 

 restricted to a specified frequency spectrum, it must be noted 

 that this is the first presentation of a formulated horizontal model 

 accounting for first-order changes in the temperature structure 

 in the sea. With further refinement in data-gathering- and - 

 reduction processes, this model should reveal more detail and, 

 possibly, a constant numerical relationship between vertical- and 

 horizontal-temperature gradients in the sea.
