Why are thunder and lightning prone to occur in high mountain areas?

Alpine areas prone to thunder and lightning are mainly large mountains that block atmospheric circulation, that is, windward slopes. The air flow is blocked by the mountains and then climbs along the terrain. After rising, the temperature decreases, and the water vapor in it condenses to form Clouds, accompanied by thunder and lightning and rainfall at the same time, are such terrains in several places with the highest annual rainfall in the world, such as Cherrapunji and Verrier.

Others, such as mountains blocking the southward direction of high pressure and mountains moving in the same direction as the air flow, this phenomenon is relatively less obvious.
