Reasons for the formation of Lushan cloud

The main reasons for the formation of Lushan cloud are as follows:

1. Topographic factors: Lushan Mountain has complex topography, undulating mountains and staggered peaks and valleys, forming rich topographic relief. This kind of topographic relief makes the air around the mountain form the superposition and convergence of airflow during the lifting process, thus generating clouds.

2. Water supply: Lushan Mountain is located in the south of the Yangtze River, with humid climate and abundant precipitation. This humid climate makes the water around the mountain fully supplied, and water is one of the important conditions for cloud formation.

3. Man-made interference: As a famous tourist attraction, Lushan Mountain attracts a large number of tourists. The activities of tourists and the waste gas and water vapor produced by a large number of tourists will have an impact on the surrounding climate conditions. For example, the smoke generated by tourists' activities and burning will provide condensation nuclei for clouds, which are easier to form.

4. Meteorological conditions: Meteorological conditions such as airflow, temperature and humidity around Lushan Mountain will also affect the formation of clouds. For example, under certain weather conditions, the rotation and uplift of airflow will form clouds.

To sum up, there are many reasons for the formation of Lushan fog, including topographic factors, water sources, human interference, meteorological conditions and so on. The combination of these factors makes Lushan a foggy place.
