What kinds of weather are there in the weather forecast?

1. Cloudy days and cloudy days in weather forecast terminology: The sky conditions are determined by the amount of clouds in the sky and the intensity of sunshine, and can be divided into sunny days, partial cloudy days, cloudy days and cloudy days. Sunny days: the sky is cloudless, or the medium and low clouds are less than 1%, and the high clouds are below 40%. Partly cloudy: there are 1-30% medium-low clouds or 40-50% high clouds in the sky. Cloudy: There are 40%-70% medium-low clouds or 60%- 10% high clouds in the sky. Cloudy day: It is dark, covered with clouds, or slightly cloudy, but it still feels dark. 2. "Turn" and "Arrival" in weather forecast: In traditional forecasting methods, the weather situation is predicted first, and then the weather elements are predicted. "Turn" and "Arrival" are actually the reflection of the weather situation changes on the weather elements. Generally speaking, it turns cloudy: it means that the weather situation will gradually deteriorate in a certain period of time in the future, and the trend is obvious. It shows that the sky changes from dark and full of clouds to clouds gradually rising, the amount of clouds decreases, and the light is transparent, as if it were sunlight or visible sunlight. From cloudy to cloudy: it shows that the weather situation will gradually improve in a certain period of time in the future, and the changing trend is not particularly obvious. The sky is dominated by darkness, mostly covered by clouds, but sometimes the amount of clouds in the sky decreases and the light transmittance is better. The sky is sometimes dark and sometimes bright. References:
