How to play the wind volume symbol and what is the wind power symbol?

There are several symbols, generally two, one is a dynamic blade rotation icon, and the other is a static stepped icon! The faster it turns, the more fan blades it displays, the more fan blades it displays, the greater the air volume! Static stepped icons: The more stairs, the greater the air volume.

Turn on the air conditioner switch, and the current display is the sun mode, which represents indoor heating. It is generally used much in winter. Press the Mode key to convert to a triangular tip symbol.

Generally, it is used when the temperature difference between day and night is large, and the air conditioner automatically adjusts according to the indoor temperature. If the temperature is high, it will be cooled, and if the temperature is low, it will be heated. It's more convenient.

Note that the temperature key cannot be set in this state. The temperature key on the right is blank. Press the "Mode" key to convert to a snowflake symbol.

Direct refrigeration. Use in conjunction with the temperature key.

Press the "Mode" key to convert to a water drop symbol. If it means that the room is hot and humid, it can be dehumidified. And the work is not continuous, only dehumidifying, and the fan does not rotate.

Press the "Mode" key to convert to a fan symbol. The air conditioning fan works, mainly to ventilate the room the next day after no ventilation overnight. Press the "Mode" key to transform into a pentagram symbol.

Set the time period, after which the air conditioner will automatically turn off. Note: Some air conditioners have a five-pointed star mode.

There are generally two representations of the air volume unit symbol: CFM (cubic feet per minute) and m3 min (cubic meters per minute).

The wind symbol is a wind vane pole with tail feathers, as shown below.

Wind has both magnitude and direction, so wind forecasting includes both wind speed and direction. The magnitude of the wind speed is often expressed in terms of the number of winds. The level of wind is determined based on the degree of influence of the wind on objects on the ground.

In terms of meteorology, it is generally divided into 13 levels according to the magnitude of the wind (17 levels for some typhoons):

In weather forecasting, it is common to hear terms such as "north wind force 4 to 5", in which case the wind refers to the average wind force; If you hear a phrase such as "gust of 7", the gust refers to the wind speed fluctuates, and the wind force at this time refers to the wind force when it is large.

Wind rating. The greater the pressure difference between two adjacent places, the faster the air flow and the greater the wind speed, the greater the wind force. Therefore, the magnitude of the wind is usually expressed in terms of wind force. The unit of wind speed is expressed in how many meters per second or how many kilometers per hour.

When issuing weather forecasts, most of them use wind ratings.

More than 200 years ago, there were no instruments to measure the magnitude of the wind, and there were no uniform regulations, and each country expressed it according to its own method. At that time, there was a man named Beaufort in England, who carefully observed the situation of various objects on land and sea in winds of different sizes, and accumulated 50 years of experience before dividing the wind into 13 grades, also known as Beaufort in 1805.

Later, after research and supplementation, the original description was explained more clearly, and the speed of each wind was added, which became the "jargon" for predicting wind power.

Wind direction and magnitude in weather symbols: represented by wind arrows, consisting of wind stalks and plumes.

Wind Direction Straw: Indicates the direction of the wind to cover the karma, and there are 8 Fangye Travel Prefecture locations.

Wind plume: A dash and a triangle indicate the force of a gale wind, perpendicular to the right of the end of the wind direction pole (Northern Hemisphere).

Level 1--2: 1 vertical bar and 1 horizontal.

Level 3--4: 1 vertical bar and 2 horizontal.

Level 5--6: 1 vertical bar and 3 horizontal.

Levels 7--8: 1 vertical bar and 4 horizontal.

Level 8 and above: 1 vertical bar 1 triangle Like a small flag wind rating table.

The following figure shows the table of wind rating symbols:

From left to right, the corresponding grades are: No Wind, 2-3, 3-4, 4-5, 5-6, 6-7, 7-8, 8-9, 9-10, 10-11, 11-12.

Wind direction and level in weather symbols: Represented by wind arrows, formed by wind direction stalks and wind feather trap group rulers.

Wind Direction Stalk: Indicates the karmic direction of the wind, and there are 8 directions for fierce behavior.

Wind plume: Indicates the strength of a strong wind by a dash and a triangle, perpendicular to the right side of the end of the wind direction rod (Northern Hemisphere) 1--2: 1 vertical bar 1 horizontal.

Level 3--4: 1 vertical bar and 2 horizontal.

Level 5--6: 1 vertical bar and 3 horizontal.

Levels 7--8: 1 vertical bar and 4 horizontal.

Level 8 and above: 1 vertical bar 1 triangle Like a small flag.
