Winter cold and dry, snowflakes fluttering, covering the whole earth, as if into a snow-covered world.

There are differences, meteorological data processing and forecasting results are different, model algorithms are different, data sources are also different,

The data collected by surface weather stations, while providing detailed surface meteorological information, are limited by the number and distribution of observation points, Sometimes unable to fully reflect the state of the atmosphere, meteorological satellites can cover a wider area, capturing the dynamics of clouds and air currents. However, the observations are also affected by factors such as atmospheric transparency.

Delays in data transmission and processing can also lead to forecast inaccuracies, and data from ground weather stations need to be transmitted to the data processing centre through the ground network. Meteorological satellite data need to be transmitted through satellite communication system, this process may have a certain time difference.

In order to reduce the forecast error and improve the forecast accuracy, it is necessary to consider all kinds of factors when using different data sources.

Differences between weather prediction models and data sources

Weather forecasting agencies rely on different models and algorithms.

Even for the same weather phenomenon, different regions may present very different predictions.

Subtle differences in the model algorithm may also lead to significant changes in the forecast.

The short-term forecast covers 1 to 3 days, the medium-term forecast ranges from 4 to 7 days, and the long-term forecast extends to more than 7 days.

Each time scale has its own unique prediction method and accuracy.

The short-term forecast relies on high-resolution models, the medium-term forecast combines numerical simulation and statistical methods, and the long-term forecast relies more on climate models.

Time scale and uncertainty of weather forecast

The short-term forecast is relatively accurate, but the uncertainty increases with the increase of forecast time.

In the short term, weather models can capture subtle changes in the atmosphere to provide more accurate weather information.

Over time, the complexity of climate patterns makes predictions less accurate.

Long-term forecasts are often faced with great uncertainty, which makes it difficult for people to make accurate judgments about future weather conditions.

Timeliness, fast-paced life so that some people can not wait too long for the update cycle, they are eager for real-time weather forecast.

The intertwined needs of different users make the presentation of forecast results diversified.

Section 5 Users' Demand and Expectation for Weather Forecast

Users crave accurate weather information, and they expect to know the exact weather conditions at their destination before they go out.

In travel planning, users need long-term weather forecasts to determine the best travel time.

For agricultural users, refined crop growth cycle forecast is very important.

For outdoor enthusiasts, the weather forecast should provide detailed wind, humidity and other indicators.

Weather forecasting requires the collection of meteorological data, such as temperature, humidity, wind speed, pressure, etc., because these data are the basis of weather forecasting models. Only with these comprehensive data can forecasters accurately judge the changes in the atmosphere and predict the weather conditions for some time to come.Meteorological satellites and ground weather stations have their own advantages in providing data. Ground weather stations can collect detailed data on the surface and near the surface. Such as temperature, humidity, wind direction and wind speed, but limited by the number and distribution of observation points, meteorological satellites can cover a wider area, The dynamics of clouds and air currents are captured, but the observations are influenced by factors such as atmospheric transparency.Weather forecasts vary from region to region, mainly due to differences in topography, climatic conditions, data sources and forecasting models. Topographic and climatic conditions will affect atmospheric movement, and then affect weather changes. The differences between data sources and prediction models will also lead to poor prediction results.Long-term weather forecasts are more uncertain than short-term weather forecasts because of the complexity and unpredictability of the atmospheric system. Weather models struggle to capture subtle changes in the atmosphere, The complexity of climate models can also lead to uncertainty in long-term forecasts.
