Weather forecast. Method.
At present, the weather forecasting methods used by meteorological observatories can be roughly divided into three categories, namely, weather map method, numerical forecasting method and mathematical forecasting method. The weather map method and numerical prediction method are mainly used for short-term forecasting, and in recent years, they have also been extended to medium-term forecasting. Mathematical statistical forecasting is mainly used for long-term forecasting, and has also developed into short-term forecasting in recent years.
In practice, the three methods are combined with each other and complement each other.

Weather forecasting is mainly the use of high technology to collect a large amount of data (temperature, humidity, wind direction and wind speed and pressure, etc.) and then use the 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 finally have a thorough understanding of atmospheric processes, for this reason there are always some errors in weather forecasting, **TV tomorrow** is mainly short-term weather forecasts.

When we were on the weather forecast program of ** TV station, we watched the host of the program tell the weather in the next two days in a few words, which seemed relaxed. In fact, this program of just a few minutes embodies the labor and painstaking efforts of tens of thousands of meteorological workers in China, and even meteorological workers around the world.
Meteorological experts said that the data observed by weather stations is the basis of weather forecasting, and the more weather stations, the more accurate the forecast. To this end, thousands of weather stations have been set up around the world, equipped with various weather radars, and a number of meteorological satellites have been deployed in space to form a global atmospheric monitoring network. This monitoring network conducts simultaneous observations at the specified time every day, from the ground to the high altitude, from the land to the sea, to observe atmospheric changes in all directions and at multiple levels, and quickly collects the observation data to the national meteorological centers of various countries, and then to the rest of the world.
The computer of the meteorological observatory processes and calculates the collected data to obtain weather maps, numerical forecast maps and other products to provide forecasters with forecast basis.
There are many ways to forecast the weather, and there are two of the most commonly used. One is the traditional method of meteorology, which is to fill in the meteorological data at the same time and at the same level on a special map, which is called a weather map. By analyzing various meteorological elements on the weather map, forecasters can understand the distribution and structure of the current weather system (such as typhoons, fronts, etc.), judge the relationship between the weather system and specific weather (such as rain, wind, fog, etc.) and its future evolution, so as to make weather forecasts in various places.
Nowadays, weather maps are drawn and analyzed by computers. The other is the numerical prediction method, which has been gradually developed with the advancement of computer technology, and the weather forecasts it makes are "calculated" by computers. Since the motion of the atmosphere follows some known laws of physics, according to these laws, the state of atmospheric motion can be written as a set of partial differential equations, and as long as the initial value (the current state of the atmosphere) is given, the variable values of the system of equations over time can be solved, and the future state of the atmosphere can be obtained from this.
The process of solving equations is extremely complex, requiring the processing of large amounts of meteorological data in a defined amount of time, and even the most simplified atmospheric equations must be computed on high-speed computers.
Whether it is a meteorological method, a numerical prediction method, or other forecasting methods, there are certain limitations, and the forecast conclusions are not the same, which requires forecasters to conduct comprehensive analysis and judgment of various forecast results. At this time, the theoretical knowledge, accumulated experience and corresponding wisdom of the forecaster are extremely important. Therefore, when the weather conditions are more complicated or before the arrival of disastrous weather, forecasting experts should hold weather consultations, and even exchange views with experts from other places and foreign countries, and on the basis of expressing their own opinions and fully discussing them, they will come up with more reliable forecasting opinions.
After the forecaster makes the forecast, he sends it to the TV program production unit for production in time, which is the chic and confident of the program host to "point out the country".

Weather Forecast: A pre-estimate and forecast of weather changes in a certain period of time in the future. Weather forecasting is an important means for meteorological work to serve the national economy and national defense construction. Weather forecasts are divided according to the forecast range, including regional weather forecasts and local weather forecasts.
According to the needs of the service users, there are daily public weather forecasts and professional weather forecasts. There are short-, medium-, and long-term weather forecasts, depending on the length of the time. Meteorological observatories release weather forecasts in a timely and accurate manner through various channels, especially disastrous weather forecasts, which play an important role in protecting people's lives and property and promoting economic development.
Weather forecasting technology was initially developed rapidly with the development of the telegraph.
By the beginning of the 50s of this century, weather forecasting had been based on the principles of meteorology. With the development of computing technology and detection technology, in addition to the conventional weather map method combined with mathematical statistical methods to make forecasts, meteorological radar and satellite detection data are also applied to forecasting services, and numerical prediction methods are developed. This method predicts the physical processes of the atmosphere by determining the conservation principle of atmospheric mass, energy and momentum, which significantly improves the quality of weather forecasting and promotes the objective and quantitative weather forecasting.

There are several ways to forecast the weather:
1. Meteorological observations:
Real-time monitoring and measurement of atmospheric parameters, including temperature, humidity, air pressure, wind direction and wind speed, etc., through meteorological observation stations, meteorological satellites, gas ballast scattering radar and other equipment, so as to provide weather data to improve future weather conditions.
2. Numerical weather forecasting:
Numerical models are used to simulate and calculate the physical and chemical processes of the atmosphere, and the weather conditions in the next few hours to days. Numerical weather prediction is based on observations of the initial state and numerical solutions to physical equations in the atmosphere, which can provide weather forecasts over a longer period of time.
3. Statistical forecasting:
Analyze and extrapolate the probabilities and trends of future weather based on historical weather data and statistical methods. Statistical forecasting can infer the likelihood of future weather development by comparing the occurrence of similar weather events in history.
4. Weather radar and satellite imagery:
Weather radar and satellite imagery can be used to observe and monitor a wide range of weather systems and precipitation. These images can provide information about rainfall, cloud maps, wind farms, and more, helping with weather changes and trends.
5. Meteorological early warning system:
By monitoring meteorological conditions and issuing alerts, people are alerted to possible weather conditions such as heavy rain, typhoons, tornadoes, etc. The meteorological early warning system can give early warning to protect people's lives and property. <>
