How to calculate the wave height in weather forecast?

Weather forecast is a necessity for everyone's life, and it is particularly important whether traveling abroad or staying at home. However, the weather forecast that people usually pay attention to is not complete, and they only pay attention to whether the weather is sunny or whether the wind is strong. Few people have a high relationship with the waves. Many people may feel that it has little to do with themselves, but it is particularly important for coastal residents, and a careless loss will come.

First, the calculation of wind power In fact, the calculation of wave height in weather forecast belongs to the State Oceanic Administration, and it is normal for many people not to understand it. Generally speaking, the calculation of wave height needs to be based on the wind force, that is to say, the wave height is calculated according to the scouring force of wind force on the sea surface, but the accuracy of this algorithm is not high, because there are many factors affecting wind force, so it is impossible to check them one by one.

Second, the wind and wave model Therefore, smart scientists have got a set of wind and wave models on the basis of years of accumulation. This third generation wind wave model eliminates many errors and takes many detours. With the continuous progress of science and technology, the data is more and more supportive, and this process also needs to eliminate the interaction between atmosphere and water flow. At this time, we need to understand that each model has its own target point and cannot be generalized.

Third, the average algorithm is compared with domestic and foreign countries. The highest value of 33 times is selected from 100 wave and recorded, and then the average value is taken. This method is more applicable in some coastal countries. Finding a system value is not as good as finding the wave height, just recording the change of the wave, and it doesn't need to be too accurate.

Many people can be forgiven for not caring about the wave height. Others think that the wave height is not a weather forecast and must be corrected. The wave height belongs to the weather forecast. Although it looks inconspicuous, it should not be underestimated. If you learn to calculate the wave height in your life, those who rely on fishery hygiene should gain a lot and avoid some unnecessary losses, right?
