Steamed bread is cloudy or sunny.

The proverb "cloud of steamed bread" describes a common cloud shape on a sunny day, which is characterized by its shape like steamed bread and usually appears in a clear sky.

Let's learn about the steamed bread cloud. This kind of cloud is round or oval in shape, with clear outline and thin cloud, which usually appears in the sky. On sunny days, the appearance of steamed bread clouds means that there is less water vapor in the sky and the air is dry, which makes it difficult to form precipitation.

Why are steamed bread clouds related to sunny days? This is because the appearance of steamed bread clouds often means less water vapor in the atmosphere and dry air. Under this condition, water vapor is not easy to condense into water droplets or ice crystals, so it will not form precipitation. Therefore, when steamed bread clouds appear in the sky, people can usually expect the next weather to be sunny.

Rumor is only an observation and summary of experience, and it cannot predict the weather completely and accurately. In practical application, we also need to combine other meteorological information, such as temperature, humidity and wind direction, to judge the weather situation more accurately.

The reason why the weather forecast is more accurate than the weather proverb;

1, scientific basis and technical support: weather forecasting is based on the theoretical knowledge of meteorology, atmospheric physics and other disciplines, and uses modern meteorological observation equipment and computer simulation technology to monitor and predict atmospheric changes in real time.

In contrast, meteorological proverbs are mainly the laws summarized by the ancients according to their long-term practical experience. Although many proverbs have certain scientific truth, they lack strict scientific verification and theoretical support. With the development of science and technology, the weather forecasting methods are constantly improved, and the accuracy is greatly improved.

2. Data collection and processing: Weather forecast depends on meteorological observation data from all over the world, including ground meteorological observation, satellite remote sensing, radar detection and other means. These observation data can reflect the atmospheric conditions comprehensively and in real time, and provide accurate basic information for weather forecast. However, meteorological proverbs often judge weather changes only by local meteorological phenomena, and data collection and processing are relatively simple, so it is difficult to achieve the accuracy of weather forecast.

3. Time limit and scope of forecast: Weather forecast can provide forecast results on different time scales (such as short-term, medium-term and long-term) and spatial scales (such as global, regional and urban) as required. This enables weather forecasting to meet the needs of different fields, such as agricultural production, transportation and disaster warning. However, meteorological proverbs can only predict the weather changes in a short time, and they are mainly aimed at a specific area, with limited time and scope.
