How accurate is the 15-day weather forecast?

The accuracy of 15-day weather forecast has always been the focus of public attention. According to a report from the Meteorological Department, the average accuracy of this long-term forecast is about 70%, which means that in the 15-day forecast, the weather conditions on 3 days may not be consistent with reality. The level of accuracy is affected by many factors, including the accuracy of meteorological equipment, the professional skills of forecasters, seasonal changes, meteorological environments and phenomena, etc.

The key factor affecting the accuracy of forecasts is the precision of equipment and technology. If meteorological instruments are not accurate enough, the data collected may be biased. Forecasters' ability to interpret and process data is also crucial, and their professionalism directly affects the accuracy of forecast results. In addition, seasonal differences and complex meteorological phenomena also pose challenges to the accuracy of forecasts.

In order to improve the accuracy of forecasts, meteorological departments need to invest in more advanced technology and equipment, while strengthening personnel training and improving the professional level of forecasters. Cooperation with relevant departments can also broaden data sources and improve the accuracy of forecasts. Weather forecasts not only serve daily life, but are also an important basis for national decision-making, helping to prevent and mitigate the impact of natural disasters and promote development in all fields of society.

There are many ways to obtain accurate weather forecasts, including TV, mobile apps, the Internet, etc., as well as following the official channels of the meteorological department. In general, although there is still room for improvement in the accuracy of 15-day forecasts, technological progress indicates that the accuracy of future forecasts will continue to improve, bringing more convenience to people's lives and social development.
