As living standards continue to improve, people's attention to weather is increasing. However, to better use weather forecasts to guide daily life, it is necessary to understand the weather forecast release rules of the meteorological station.
The content of the forecast varies depending on the time the forecast is made. According to regulations by the meteorological department, the start and end times for weather forecasts are based on 8:00 AM and 8:00 PM. For example, urban weather forecasts, which people care about the most, are usually released twice daily at 5:00 AM and 5:00 PM. Therefore, the 24-hour forecast released at 5:00 AM refers to the weather forecast from 8:00 AM that day to 8:00 AM the next day, with the forecast language being "today during the day to tonight". The 24-hour forecast released at 5:00 PM refers to the weather forecast from 8:00 PM that day to 8:00 PM the next day, with the forecast language being "tonight to tomorrow".
Since under normal circumstances, the highest temperature of the day occurs in the afternoon, and the lowest temperature occurs in the morning (before sunrise), the order of releasing the highest and lowest temperatures differs depending on the release time. In the 5:00 AM forecast, the highest temperature is for the daytime temperature of the same day, and the lowest temperature is for the early morning temperature of the next day. In the 5:00 PM forecast, the lowest temperature is for the early morning temperature of the next day, and the highest temperature is for the daytime temperature of the next day.
For example, at 5:00 PM on November 20th, the 24-hour forecast for Jinan City was "Jinan, partly cloudy turning to clear, 8℃-14℃", meaning "from the night of the 20th to the day of the 21st (from 8:00 PM on the 20th to 8:00 PM on the 21st), the weather in Jinan will be partly cloudy turning to clear, with the lowest temperature at 8℃ in the early morning of the 21st, and the highest temperature at 14℃ during the day on the 21st." On November 21st at 5:00 AM, the 24-hour forecast for Jinan City was "Jinan, clear, 15℃-6℃", referring to "from the day of the 21st to the night (from 8:00 AM on the 21st to 8:00 AM on the 22nd), the weather in Jinan will be clear, with the highest temperature at 15℃ during the day on the 21st, and the lowest temperature at 6℃ in the early morning on the 22nd."
