Why is the weather forecast not absolutely accurate?

The weather forecast is only based on the combination of clouds, airflow, air humidity and past experience.

Accuracy is not 100%,

People in China are very clever, and they told people about the weather forecast before they invented it.

"The weather is unpredictable." .

Weather forecast is based on the summary of weather conditions under the same or similar meteorological conditions in the past, plus the current influencing factors, and the probability of possible weather conditions in the future is obtained, which determines that it is impossible to be 100% accurate. In short, due to the limited level of science and technology, meteorologists can only judge the general situation of the weather according to the general direction of the airflow, ignoring the potential small interference factors. You know, there are still many phenomena in nature that are elusive to human beings. Some interference factors that are considered unimportant are likely to be transformed into larger interference factors in an instant, and many times human reactions can't keep up with the changes in nature.

Under certain conditions, no prediction of the future can be 100% accurate unless you are a god.
