The season with the highest frequency of horseshoe vortex clouds.

The season with the highest frequency of horseshoe vortex clouds is summer.

Horseshoe vortex cloud, also known as horseshoe cloud, is a very rare natural phenomenon, which usually lasts only 1-2 minutes and then evaporates and disappears. It is formed by a rotating upward airflow, which can cause clouds to appear horseshoe-shaped. Horseshoe vortex clouds usually appear in thunderstorm weather, especially near supercell thunderstorms.

Summer is the most common season of thunderstorm weather, especially in July and August, which is the peak of horseshoe vortex clouds. This is because in summer, the ground is heated by solar radiation, which leads to the increase of water vapor evaporation in the atmosphere, thus increasing the formation of clouds and precipitation.

In addition, summer is the typhoon season, and the strong winds and heavy rains brought by typhoons also provide favorable conditions for the formation of horseshoe vortex clouds. Horseshoe vortex cloud is not only a rare natural phenomenon, but also a beautiful landscape. Its appearance often indicates that there will be a thunderstorm, so it is called a prelude to a thunderstorm.

Characteristics of horseshoe vortex clouds;

1. Unique shape: horseshoe vortex cloud, also known as crop circle cloud, is characterized by its unique horseshoe or oval shape. This cloud has a clear structure and neat edges, and looks like a huge horseshoe printed in the sky, hence its name.

2. Stable shape: The horseshoe vortex cloud is relatively stable in shape and will not be easily blown away by the wind. This is because the formation of this cloud needs the cooperation of specific weather conditions and wind direction. Once formed, its shape can be maintained for a long time unless these conditions change significantly.

3. Amazing visual effects: Horseshoe-shaped vortex clouds can often produce shocking visual effects because of its rare shape and huge scale. In the clear sky background, such clouds are particularly prominent, and sometimes they are even mistaken for some mysterious natural phenomenon or artificial artistic creation.
