First, the weather forecast is in a basically accurate state.
Personally, I think the weather forecast is actually quite accurate, because in most cases, I don't have much error after seeing the weather for the next day the day before.
Many people will complain that the weather forecast is not accurate, in fact, I can understand it better, because the weather forecast is only an approximate range, which city he expects to rain, but each area of each city is very wide, so there will still be some differences between each region. I'm a person who is used to reading the weather forecast, and I will predict what the weather will be like tomorrow tonight, and then I will dress according to the weather conditions, and it will not make much difference under normal circumstances.
Second, the weather forecast is actually very difficult.
Weather forecasting is a very complex system, and if there is a slight error in the calculation, then it will be very different, and there is a lot of data in our calculation scheme that is not accurate enough.
Because we humans do not have a complete grasp of the laws of atmospheric motion, it is difficult to calculate its accuracy. Another aspect is that the topography of each region is not the same, so the weather will still have a certain impact on the topography, which will bring different weather in each region, and it is not accurate; Another aspect is that China currently lacks some talents in monitoring and early warning capabilities, and some weather forecasters.
It's overly dependent on numbers, so it's hard to get accurate weather.
3. Weather forecasts are also to help people understand the weather.
Personally, I think that the weather forecast is to help people understand the weather conditions, so that it is more convenient for people to farm or dress and travel according to the weather.
Although there is still a certain difference in the accuracy of the weather forecast, we can basically understand his weather situation slowly, so the current weather forecast is enough for our daily needs, and it does not affect us to go out or farm. Therefore, I still have a more understanding attitude towards the inaccuracy of the weather forecast.
-
In fact, most of the weather forecasts are relatively accurate, but the weather is affected by many factors, and it may be difficult to get, so we can't think too much about this matter because of our own subjective assumptions, maybe we are not engaged in this work, and they have also put a lot of effort into it.
-
To be honest, I think the weather forecast is really inaccurate. It is said that the difficulty is very high, and it is only scored 5 stars. It is released through meteorological observations, data collection, comprehensive analysis, forecast consultations and forecasting products.
-
Accurately, there is a great difficulty behind the weather forecast, because the weather station needs to accurately analyze the weather, to see when it rains and when it is windy.
-
Weather forecasts are **weather, there is no complete accuracy and there is no eternal accuracy. Weather forecasting should be analyzed and calculated through meteorological satellite images in combination with the atmospheric environment, temperature, humidity, precipitation area, and precipitation factors. So the difficulty is quite high!
-
I think the weather forecast is very accurate now, look at the weather forecast, if it is cloudy and light rain in the afternoon, when the sun is shining in the morning, I think the weather forecast may be wrong, but it rains lightly in the afternoon. Now the technology of weather forecasting has basically matured, thanks to the hard work of scientific and technological workers.
-
Relatively accurate, the difficulty is very great, although the technology is very developed now, but also need to be assisted manually, they must be accurate and accurate, in order to provide convenience for people's lives.
-
It is also relatively accurate, and at the same time it is particularly difficult, to observe the phenomenon of the weather, but also to integrate meteorological data, but also to summarize.
-
Accurately, because there is a lot of difficulty behind them. Data observation is also very rigorous.
-
Nine out of ten are not allowed, competing for eyes to report nonsense.
-
In today's era, science and technology are so developed, the weather forecast is still backward, and it can only be accurate on the same day.
-
How developed science is, weather forecasts are inaccurate,
-
Sunny, cloudy, and cloudy days account for 98%, rainy days, and snow days account for about 90%, and the probability of bad weather such as fog, hail, and sandstorms is very small, so the proportion is high。The temperature and wind are generally very accurate, and the weather forecast is only predicted in advance, and in general the accuracy is still very high. Weather forecasting or meteorological forecasting is the use of modern science and technology to determine the state of the Earth's atmosphere at a certain location in the future.
Weather forecasting is mainly used to collect large amounts of data (temperature, humidity, wind direction and speed, air pressure, etc.) and then use current knowledge of atmospheric processes (meteorology) to determine future air changes. Due to the confusion of atmospheric processes and the fact that science today does not ultimately have a thorough understanding of atmospheric processes, there is always a certain amount of error in weather forecasting.
Forecasting process
The most traditional data is data on air pressure, air temperature, wind speed, wind direction, humidity, etc., collected on the ground or at sea through professionals, hobbyists, automatic weather stations or buoys. The World Meteorological Organization coordinates the timing of these data collections and sets standards. These measurements are measured once per hour (METAR) or every six hours.
Data from meteorological satellites is becoming increasingly important. Meteorological satellites can collect data from all over the world. Their visible light** helps meteorologists to see how clouds are developing.
Their infrared data can be used to collect temperatures on the ground and at the top of the clouds. By monitoring the development of the cloud, you can collect wind speed and direction at the edge of the cloud. However, because the accuracy and resolution of meteorological satellites are not good enough, ground-based data is still very important.
-
The accuracy of forecasting cannot be generalized, otherwise it is unscientific.
1) There are great differences in the forecasting ability of different weather elements, for example, for the forecast of sunny and rainy, precipitation, temperature, hail and other elements, because the temperature is a continuously changing element, the forecast always has an error of 3 to 4, which is difficult to report accurately.
2) The weather forecast is also divided into places, such as the winter in Beijing, if the forecast of sunny days every day, the accuracy rate may reach 90%, and the south of China will not be so high.
3) For the forecast of medium- and long-term (3 7 days) weather phenomena, especially the forecast of weather conditions, the accuracy of numerical prediction is much higher than that of the forecaster's subjective judgment. However, when the time limit is extended to 15 days, or even 30 days, it is difficult for numerical predictions to have practical value.
-
The accuracy is about 80 percent. Because of natural factors. It's always changing. Sometimes it may not be accurate.
-
It should be 90 percent white! After all, there are unforeseen circumstances, and it is already very accurate to use high technology to achieve this level!
-
It's very not, just take it as a joke.
Do you know how the so-called "probability of precipitation" in weather forecasts is calculated?
For example, there are 10 employees at a certain weather station, and the director of the station says: "I think it will rain tomorrow and raise my hand."
Assuming 3 people raise their hands, the probability of precipitation tomorrow is 30%.
-
Now the weather station is advanced, unlike before, looking at the clouds to know the weather! It should be above 90 percent.
-
This is because the weather is changeable, and the staff has a heavy workload, which is prone to mistakes.
-
Mainly because the clouds move very irregularly, so it is impossible to make a weather forecast as accurately.
-
The weather forecast on your phone is not very punctual, and if you want to get a very accurate weather forecast, you need to check the special weather forecast**. Weather forecasts are based on satellite cloud imagery.
-
Hello, the accuracy rate of the weather forecast is above 80%. **The forecast of the meteorological station is more accurate within three days, and the forecast of the local meteorological station is more accurate within two days. Under normal circumstances, the accuracy rate is 95% in 24 hours, about 90% in 48 hours, and about 60% in weather forecasts within 96 hours.
