Movie of Pacific Surface Winds
This animation shows ocean surface wind speeds and directions over the Pacific as measured by the NSCAT scatterometer on September 20, 1996. Here, wind speed is depicted by the color of the ocean background: blue for low winds, red for moderate winds, and yellow for high winds. The movement of the white arrows shows the direction of the wind at about 00:00 GMT. The underlying wind field was constructed from eight orbits worth of NSCAT data by using a successive correction interpolation scheme. Noteworthy features manifested in this scene include: typhoons Violet and Tom in the North-Western Pacific near Japan, the trade winds and inter-tropical convergence zone near the equator, and strong winter storm activity in the Southern Hemisphere.
