The mechanism of the formation of floods
« on: April 21, 2018, 05:16:40 AM »
The waters of the lakes, seas and oceans of the northern hemisphere rotate counterclockwise, and the waters of the southern hemisphere rotate clockwise, forming cyclonic gyres.
The main cause of rotation of gyres are local winds, flowing into the seas and oceans of the river and the deflecting force of Coriolis.
https://en.m.wikipedia.org/wiki/Ocean_gyre

And the higher the speed of the winds, the higher the rotational speed of the gyres, thereby increasing the centrifugal force of the gyres and, as a result, the water level of the seas and oceans increases.
And the lower the rotation speed of the gyres, the lower the water level of the seas and oceans.

The speed of currents along the perimeter of the seas and oceans is not the same everywhere and depends on the depth of the coast.
In the shallow part of the seas and oceans, the flow moves fast, and in the deep water part of the seas and oceans the flow moves slowly.

Seasonal increase in the water level is observed not along the entire coast of the seas and oceans, but only on those coasts where a high angular velocity of currents and, as a result, a high centrifugal force of water. (Centrifugal force F = mv2 / r).
On straight coasts where currents do not have an angular velocity, the water level does not rise.

The waters of the Gulf of Finland rotate counterclockwise, forming a cycle in the form of an ellipse.
And when the seasonal storm westerly winds and the deep Neva River unleash the gyre of more than 7 km / h, the centrifugal gyre of the gyre increases, making the water level on the east coast of the Gulf of Finland more than 3 meters.
A similar pattern of seasonal increase in water levels is observed in all lakes, seas and oceans.

The average depth of the Gulf of Finland is about 50 meters, on the east coast about 5 meters, in the west of the bay about 100 meters. For this reason, on the east coast of the Gulf of Finland, the linear and angular velocity of the currents is much higher.
As far as the depth of the coast decreases, the speed of the currents increases.

In the Gulf of Finland, the seasonal increase in water levels has two peaks; in August-September and in December-January and in time coincide with the season of westerly winds and the high water of the Neva River.
The speed of the current in the Gulf of Finland exceeds 7 km / hour, and the maximum speed of the current on Earth reaches 30 km / hour, the wind speed is more than 100 km / hour.
If the storm wind moves in the direction of the current for several days, then the speed of the current increases several times.
The speed of the current depends on the wind speed, the duration of the wind and the height of the waves.
With an increase in wave heights, the windage of the waves increases and, as a result, the angle of attack of the wind increases.

The waters of the North Sea rotate counterclockwise, forming a huge circulation.
And when seasonal storm winds unleash the cycle, up to 20 km / h (on the southern coast), the centrifugal force of the cycle increases, so that on the southern coast of the North Sea the water level rises more than 5 meters.
(The storm surge is more than 2.5 meters, the centrifugal surge is more than 1 meter and the tides are more than 5 meters).

The waters of the Caspian Sea rotate counterclockwise, forming a circulation in the form of an ellipse.
And when the deep-flowing Volga River spins the circulation more than 10 km / h, the centrifugal power of the circulation increases, so that on the northern coast of the Caspian Sea the water level rises more than 1 meter.
Centrifugal surge is an invisible water block at the mouth of the river.

The average depth of the Caspian Sea is about 200 meters, on the north coast about 5 meters, on the south coast about 500m.
For this reason, on the northern coast of the Caspian Sea, the linear and angular velocity of the currents is much higher.
In the Caspian Sea, the peak of the seasonal water level increase is observed in June-August and coincides in time with the flood of the Volga River.
During a drought over the Volga River basin, the water level in the north of the Caspian does not rise.

In the Bay of Bengal, in the season of monsoon winds and floods of the Ganges River, the speed of rotation increases over 10 km / h, due to which the seasonal rise in water levels exceeds 15 meters.
(The storm surge is more than 2.5 meters, the centrifugal surge is more than 1.5 meters and the tides are more than 10 meters).

The seasonal increase in the level of the Black Sea (up to 40 cm) is most pronounced in the southeastern part of the sea, where in summer the angular velocity of the currents along the coast reaches its maximum value.

The height of the floods depends not so much on the speed and direction of the wind, but on the speed of rotation of the cycle, due to which centrifugal surge and abnormally high tides are formed.
For this reason, on different coasts with the same wind speed, the height of floods varies.
In St. Petersburg, small floods occur during the calm and with the east wind.
Storm surge of high altitude in the Northern Dvina River can be formed under the influence of the north wind.

If during a storm the deep rivers that flow into the bay do not create a whirlpool or the storm wind moves against the whirlwind, then the flood does not form and is easy to predict.

The rotational speed of the gyre in the Gulf of Finland can be significantly reduced if the flow of the Neva River is directed against the currents of the Gulf of Finland, with the help of the St. Petersburg Flood Protection Complex.
To do this, 1-5 days before the flood, you need to close the flood gates of the northern branch of the dam.
(The gateway can not be closed).
And the flood gates of the southern branch of the dike close before the flood.

At the same time, a fully enclosed dam creates ideal conditions for the formation of a diurnal tidal wave, whose amplitude depends on the depth of the coast and the speed of the current along the dam.
In the Gulf of Finland, the storm surge height reaches 1.5 meters, the centrifugal surge 0.5 meters, and the daily tides are 2 meters.
The reason for the lowering of the water level in the Gulf of Finland before the flood is the formation of a tidal hump in the throat of the Gulf of Finland.

The assumption that the cause of the seasonal increase in the water level can be the pressure of the atmosphere, the flow of the rivers, the temperature difference and the salinity of the water do not hold water, these factors may raise the water level by several cm, but not more.
The presented theory can be easily verified by relating the speed of the current along the coast with the level of the seas and oceans.
(Based on a map of depths and currents, seas and oceans).

Dear Climatologists!
I propose to use the theory presented for weather forecasting in seas and oceans.

Yes floods are caused by .... rain

Some floods are caused by dam failures, or storm surges.

:) Like the insurance agent will say, when is a flood not a flood?

It is not a flood when you try to make a claim, despite having overland water coverage.
