What is it called when it rains on a sunny day?

Rain on a sunny day is called solar rain.

In meteorology, the phenomenon that the sun and rain appear simultaneously is called solar rain. Solar rain usually appears in summer. There are many reasons for its formation, some of which are caused by dark clouds in the distance being blown to another place by strong winds. Some clouds with different charges collide with each other under the action of the solar wind, resulting in excessive water vapor content in the air in some areas and rapid evaporation of water vapor by solar radiation.

Besides, the weather suddenly changed and it began to rain. The rain in the sky has not yet fallen, and the clouds have disappeared, so it looks sunny, but in fact it is raining again. The duration of solar rain is short and the amount is not large. "It rains on a sunny day, planting yellow seedlings and eating white rice." It refers to solar rain, which is considered as a good omen for sheep harvest when sowing seedlings.

Introduction of magical weather landscape:

1, Yuzan

Rain flag is a meteorological phenomenon, which mostly occurs in strong convective weather. It is a streak-like overhang formed at the bottom of the cloud by the continuous evaporation and disappearance of raindrops during the falling process. Because the striped raindrops or ice crystals hanging at the bottom of the cloud float with the cloud and look like flags, it is named. However, because the air is dry, rain and snow evaporate in the air before landing, thus forming the phenomenon of air precipitation. So in dry and warm places, such as some arid areas in northwest and north China, there are more opportunities to see rain banners.

2. Downburst

Downburst is a weather phenomenon that often occurs in the strong convective summer season, and it is a local strong downdraft, which is mostly generated and developed in strong thunderstorm clouds. When it happens, it usually appears as a strong airflow rushing from the sky to the ground. After touching the ground, the airflow will spread in all directions, but generally it mainly spreads in the direction of thunderstorm clouds, producing strong winds parallel to the ground, and the closer to the ground, the greater the wind speed.
