Why is the weather different on both sides of the Flame Mountain?

People who have lived in northern Taiwan Province Province for a long time will notice that the rainy days in winter are particularly long? However, in the south-central region, after entering 10 every year, it is always sunny until the rainy season comes the following year, and it is rare to have a few rainy days.

The weather difference between north and south is in sharp contrast? In winter, people who used to drive on the highway may have an experience. When the car goes from north to south, the sky is always so gloomy, especially in Miaoli area, which is often foggy. How can I tell, through so many clouds? . However, as soon as I crossed the flaming mountain and went down to Da 'anxi Bridge, the warm sunshine suddenly appeared, and another blue sky appeared in front of me, which made people feel cheerful? Why is the weather so different just across a mountain? Because the thickness of the northeast monsoon of cold and humid air in winter is mostly below 2000m, which is influenced by the central mountain range in the northeast of Taiwan Province Province with an altitude of more than 2000m? Blocked by snow-capped mountains, it has become a spent force in the area of Flame Mountain? Unless the northeast monsoon is particularly deep, the low-level clouds and topographic precipitation generated on the windward side are not easy to cross the mountains and affect Taichung area. So the flaming mountain has become a natural dividing line, and the natural scenes in the south and north of the mountain are very different?
