Streamlines Colored by Wind Speed

This shows streamline change every hour from August 17, 2018 at 12:00 to August 24, 2018 at 06:00. The color of the line indicates the speed of the wind. The closer the color to red, the greater the wind speed. We referred to the NCL site’s code.

A streamline is a hypothetical curve (gradient flow) which is a continuous line drawn as the tangential vector direction of each point in the fluid coincides with the direction of motion of the fluid. You can see the shape of the fluid flow and the speed of fluids
