Modern forecast of weather forecast

Modern weather forecast has five components:

1. Collect data

Using weather balloons, meteorologists can also collect air temperature, humidity and wind force. Weather balloons can rise all the way to the tropopause.

3. Weather radar can provide information about precipitation area and intensity. Doppler radar can also measure wind speed and direction.

4. Data weather forecast

Digital weather forecast uses computers to simulate the atmosphere. Based on the results of data assimilation, it calculates the changes of the atmosphere with time according to the results of physics and fluid mechanics. Because the equations of fluid mechanics are very complicated, digital weather forecast can only be carried out by supercomputers. The output calculated by this model is the basis of weather forecast.

In the past, meteorologists had to do their own processing work, but today's weather forecast over 24 hours mainly uses a variety of different models to synthesize the results. Meteorologists must also analyze the predicted model data so that end users can understand it. In addition, the resolution of weather forecast models is generally not particularly high. Local meteorologists must also consider the influence of the region through local experience to make the local weather forecast more accurate. However, with the continuous refinement of the weather forecast model, this workload is getting smaller and smaller.

For end users, the display of weather forecast is the most important in the whole process. Only by knowing what information the end user needs and how to convey it to the end user easily can this task be completed.
