Why are lightning weather prone to occur in mountainous areas?

The mountainous areas prone to lightning weather are mainly large mountainous areas that block atmospheric circulation, that is, windward slopes. After the airflow is blocked by the mountains, it climbs along the terrain, and the temperature drops after rising. The water vapor condenses into clouds, accompanied by lightning and rainfall. Several so-called places with the largest annual precipitation in the world are such topography, such as Kilaupunqi and Willell.

Others, such as mountains blocked by high pressure to the south and mountains with the same airflow, are relatively inconspicuous.
