What is the weather reason for the plane delay?

Due to weather problems such as meteorological thunder, rain and fog, the flight is unseaworthy and the delay is the most, which is a force majeure factor. Many times, it is normal for passengers to see the sunny weather in front of them, but they are told that the flight is delayed due to the weather. Because the weather not only refers to the weather at the destination airport, but also the weather on the route is not seaworthy. There are also flights to a certain place, some can go, some can't go, and passengers are told that it is the weather. What happens is that the standard of take-off and landing is related to the model; In addition, the specific safety standards set by the same aircraft in various airlines are also different, and the captain's decision on the current weather and trends is also different. According to the Civil Aviation Law, "the pilot-in-command has the right to refuse to fly if he finds that the civil aircraft, airport and meteorological conditions do not meet the requirements and cannot guarantee flight safety". Whether he can take off depends on the captain's judgment on the state of the plane, the airport and the weather.
