Except for a slight dis- crepancy in surface temperature, the agreement between the predicted and observed temperature distribution must be considered good. If the depth of the thermocline as predicted above would remain con- stant for a reasonable period of time, it could be concluded that a possible method of predicting the thermal struc- ture had been developed. However, another factor remains which requires investigation. It is noted that the thermocline oscillates in a periodic manner which In no way can be attri- buted to the effect of meteorological variables. It was considered that this problem must be considered before adequate means of predicting the thermal 31
