Sea Surface Symptoms
Sea Surface is Calm
Microwaves are like fish scales, without waves
Small waves, short waves, obvious waveform, smooth but unbroken crests Small waves increase, crests begin to break; foam is bright, with occasional white waves and small waves, and the wavelength becomes longer; white waves appear in groups, with a more obvious long wave shape; many white waves are formed, and many splashes are avoided
Mild waves begin to form; there are large white foams everywhere on the crests, and sometimes there are splashes
Mild waves, breaking waves into white foam
Medium waves, with a longer wavelength, waves The edge of the peak begins to break into flying foam pieces, and the white foam is distributed in obvious strips along the wind direction
Raging waves, the white foam is densely striped along the wind direction, and the wave crest begins to roll; the flying foam can affect the horizontal visibility
Raging waves, the wave crest rolls with long rain; the white foam appears in pieces, and the wind direction is white; the sea surface is more turbulent, there is a sense of vibration, and the horizontal visibility is affected. Abnormally raging waves (small and medium-sized ships may be temporarily hidden in the back waves); the sea surface is completely covered by white foam pieces blown out along the wind direction; the waves are broken into foam everywhere; the horizontal visibility is affected
Raging waves, white waves and flying foam appear in the air, seriously affecting visibility. The wave level should comply with the provisions of GB/T12763.2. See Table 7 for wave levels.
