It is mainly caused by location, topography, winter and summer monsoon, typhoon and other factors. Huoshaoliao is located on a hillside 420 meters above sea level at the northeast end of Taiwan Province mountain range, facing the sea. In summer and autumn, the humid summer monsoon and typhoon blowing from the southeast sea are lifted by the terrain when landing, and the precipitation is abundant; Winter is influenced by the northeast monsoon.

Because the northeast monsoon passes through the vast ocean, especially after passing through the warm water surface of Kuroshio, the water vapor increases sharply, and when the airflow reaches Huoshaoliao, it is lifted by the terrain and forms a lot of precipitation. According to statistics, from June 1 1 to March of the following year, the winter precipitation in Huoshaoliao accounts for half of the total annual precipitation. Because there is a lot of precipitation in both winter and summer, burning the fire has become the "rain pole" in China.

Characteristics of burning materials

Every year, typhoons in summer and autumn, northeast monsoon in winter and southeast monsoon in summer will form topographic precipitation here. Another kind of fire is the only way of summer monsoon, which is deeply influenced by summer monsoon.

Therefore, the northeast monsoon from September to March every year carries a lot of water vapor south, where it is intercepted by the terrain to form dense rainfall; Every summer and autumn, the instantaneous rainfall of typhoons is even more amazing, so it is called the rainstorm center of Taiwan Province and the area with the largest annual rainfall in China. Now Huoshaoliao is in danger of being submerged by the planned Pingxi Reservoir.
