In addition to northwest rain, what other special weather conditions does Taiwan have?

Due to its geographical location, terrain, latitude and other special climatic conditions, Taiwan has many special weather conditions. Here are a few for reference~

Fire wind, mountain wind, flaming mountain, mad dog Waves and so on~

1. Fire wind (also called foehn wind), Taitung is located on the leeward side of the westerly wind, and the humid air in South China encounters Taiwan's north-south direction of more than 3,000 meters

Alpine mountains are forced to rise. Due to the cooling effect of expansion, the water vapor contained in them condenses into clouds or rain and falls on the windward side, leaving dry air.

Crossing the mountains and descending, through the process of adiabatic compression, Produces abnormal warming, forming what is commonly known as fire wind.

2. Downhill wind ~ subduction along the slope.

Taiwan's alpine mountains extend from north to south to the Hengchun Peninsula. The terrain to the south of Fangshan Mountain is low, with the average height mostly below 1,000 meters.

Due to the thick easterly wind layer, it is not blocked by the terrain. It is possible to cross the southern end of the alpine mountains and rush down along the slope of the west side of the valley. Fangshan, Fenggang, Hengchun, etc.,

cause strong downhill winds, which are locally called downhill winds. During the occurrence of downhill winds, the temperature in Hengchun not only did not rise, but actually dropped.< /p>

It is completely different from the cause of fire wind.

3. Flame Mountain ~ the boundary between cloudy and sunny.

The Sanyi area of ​​Miaoli is often filled with clouds and fog, but once the flames pass Mountain, go downhill to Da'an River Bridge, the sun suddenly appears, and the blue sky appears in front of you.

There is such a big difference in weather just across a mountain. This is due to the northeast monsoon carrying cold and humid air in winter. , in the northeastern part of Taiwan, it is blocked by alpine mountains and snow-capped mountains with a height of more than 2,000 meters.

Unless The northeast monsoon is particularly deep. Generally, due to topography, low-level clouds and orographic rain are produced on the windward side, which are difficult to pass over the mountains and affect the Taichung area. Therefore, the Flame Mountain has become a natural boundary, between the south of the mountain and the north of the mountain. The natural scene is very different.

4. Crazy dog ​​waves~suddenly

Before the winter cold wave passes, the northeast monsoon prevails, or the summer typhoon comes, sudden waves often occur along the northern coast of Taiwan.

Three big waves appeared in succession each time, lasting about 2 or 3 minutes, and then calmed down. After a while, the waves suddenly rose again, like a mad dog,

So local fishermen said It's called a "mad dog wave".

Because this phenomenon occurs very suddenly without any obvious warning in advance, inexperienced people fishing on the beach are hit by this sudden wave.

They are often swallowed by huge waves because they cannot escape. One theory is that the cause of crazy dog ​​waves is related to long waves triggered by air pressure.

Long waves propagate quickly and reach the coast, because the seabed along the coast becomes shallower. This doubles the wave height and amplitude. But its real cause still needs to be studied in depth.
