How to draw tidal waves?

The wave painting method of tide watching is as follows:

1. Draw a wavy line first.

2. Then draw two lines to form a wave shape.

3. Then draw a half cloud shape with wavy lines, and be careful not to seal it on the left.

Draw a sharp shape on the left and connect it to form a wave.

5. It is also necessary to connect waves with arcs.

6. You need to draw a shorter wave on the right in the same way.

7. finally, color.

The shape of waves

Waves are divided into wind and waves, swells and nearshore waves. The fundamental cause of these three kinds of waves is the waves produced by the action of wind. Surge is a wave produced by the change of topography or wind direction in the open sea. Nearshore waves, offshore waves, or swells that react with the shore after reaching the shore, and then change the wavelength and period.

Wind waves, swells and nearshore waves are several centimeters to more than 20 meters high, up to more than 30 meters. Wind waves are waves produced by wind, and many waves with different heights and lengths can appear at the same time. The wave surface is steep and the wave length is short. There are often waves or foam fragments near the peak, and the propagation direction is consistent with the wind direction.

The longer the wind in the same state acts on the sea surface, the greater the wind waves; The wind and waves will not continue to increase if they reach full growth. The waves formed after the wind and waves leave the wind-blown area are called swells. According to the wave height, the wind and waves are usually divided into 10, and the surge is divided into 5 levels. Level 0 has no waves and surges, and the sea level is like a mirror; Level 5 waves and level 6 waves correspond to level 4 swells, and the wave height is 2-6 meters; Grade 7 wild waves, grade 8 wild waves and grade 9 wild waves correspond to grade 5 huge waves with a wave height of 6. 1m ~ 10m.
