What is the scientific basis for forecasting sunny and rainy days?

Weather forecast He actually uses modern science and technology to predict the atmospheric conditions of the earth somewhere in the future, and because prehistoric people have begun to predict the weather, they have arranged their work and life accordingly, such as agricultural production and military operations. Until today, weather forecasting is mainly used to collect a large number of data, such as temperature, humidity, wind direction, wind speed, air pressure and so on. , and then use the current understanding of the atmospheric process, in short, is to determine the future air changes.

Moreover, due to the chaos of the atmospheric process, and today's science has not finally got a thorough understanding of the atmospheric process, the weather forecast is always wrong, and it is not 100% accurate. Probably recently, we should all know that there are many factors affecting the occurrence of high temperature weather. For example, around 20 16 years ago, because of the influence of super El Nino, the hot weather was called the hottest year in history.

Moreover, 20 16 is the hottest year since the instrument was recorded, and the global ocean and land surface temperature has broken the record of 14 months. Although affected by super El Nino, the reason behind it is global warming, which leads to frequent extreme weather. Secondly, in the near future of 20 16, 20 19 was the second hottest year since musical instruments were recorded, because by the end of 20 19, the global average temperature had increased by 1. 1 Celsius compared with that before industrialization.

According to the forecast of the World Meteorological Organization, there may be a record high temperature in 2020, because Seymour Island near the Antarctic Peninsula broke the record on February 9, 2020. It has been recorded that there has been a high temperature of 20.75℃ since the highest temperature was measured. Moreover, since the meteorological record, 65438+ 10 in 2020 is still the hottest 65438+ 10.

What is the scientific basis for forecasting sunny and rainy days? Let's call it a day.
