| COMPARISON BETWEEN RECKONING DATA AND GEK DATA |
|
|
| Abstract: |
| Based on "Oceanographic and Meteorological Observations in the China Sea and in the Western Part of the North Pacific Ocean" by Holland Royal Institute and on the "Oceano-graphic Environment" by SHO. Some comparison were made between the surface current from the reckoning data and that from GEK data. The results are as follows: 1. The direction of the current from reckoning data are a little more to the right than to the left whether in winter and summer. 2. Because the reckoning data were effected by seasonal wind, the velocity decreased (increased) in winter (summer). The standard deviation of the velocity is less in winter than in summer, but the criterion deviation of the direction is less in summer than in winter. 3. Effect of seasonal wind in the reckoning data for the East China Sea is remarkable when the direction of the wind and the direction of current coincide, in summer the velocity increases and the direction of current is about 2/3 to the right in Regions Ⅰ-Ⅲ. 4. In Region Ⅱ (Kuroshio) the reckoning data is more reliable than in Region Ⅰ and Ⅲ, but in Region Ⅰ and Ⅲ the standard deviation of velocity is less in winter than in summer, and the criterion deviation of the direction is bigger in summer than in winter. |
