Waves called periodic fluctuations surface seas or oceans. Today, let's see stunning images of waves photographer Ryan Pernofski.
Depending on the causes of the movement, different waves of wind, tidal (tides), pressure (seiche or standing waves) and seismic (tsunami).
The waves are characterized by a height equal to the vertical distance between the wave crest and sole length - the horizontal distance between two adjacent ridges, and the propagation velocity period.
In the wind wave period lasts about 30 seconds, from the barometric and seismic - from several minutes to several hours. In tidal period is measured in hours.
The reservoirs are the most common wind waves. They are formed and developed through the wind energy transferred water due to friction, and by the pressure air flow to the slopes of the wave crests.
The waves are always there in the open ocean and can have a variety of sizes, reaching lengths of up to 400 m, a height of 12-13 meters and the propagation velocity of 14-15 m / s.
The maximum recorded height of wind waves is 25-26 meters, although it is possible the existence and the higher waves, simply do not know about.
In the initial stage of development of the wind waves running in parallel rows, which are then split into separate combs. Small waves depth limit growth.
If the wind that caused the excitement subsides, the wind waves are converted into t. N. swell. It often occurs simultaneously with vetrovymivolnami, it does not always coincide with them in the direction and height.
. In the surf zone observed r. N. surf runout - periodic ups water level when approaching the group of high waves. The lifting height is typically from 10 cm to 2 meters.
