METHOD AND APPARATUS FOR FORMING WATER TEMPERATURE PROFILE DATA

PURPOSE:To obtain annexed data conforming to ocean environment by calculating extrapolation data from actually measured data while calculating interpolation data from the past data and a set asymptotic line and calculating the data from a certain to the bottom of the water by the linear connection of both data. CONSTITUTION:Water temp. profile (X-BT) data from the surface of the water to a certain depth and the water temp. profile (H-BT) data from the surface of the water to the bottom of the water calculated in the past are loaded into an interpolator 12 from an input terminal 11 and the H-BT data is also taken in an asymptotic value forming means 13. The means 13 sets an asymptotic value TMN to output the same to an extrapolation function calculation means 15 and an interpolation function calculation means 16 and the interpolator 12 outputs a plurality of depth sampling points containing the upper and lower limit depths ZN, ZT of a region, the X-BT data and the H-BT data to a weighting function calculation means 14 and the means 15, 16 and the means 14, 15, 16 output a weighting function n(Z), an extrapolation function TA(Z) and an interpolation function TB(Z) to a weighting adder 17 respectively and the adder 17 calculates annexed water temp. profile TMRG(Z) to output the same to an output terminal 18.
