Besides northwest rain, what special weather is there in Taiwan Province Province?

Taiwan Province Province has many special weather conditions due to geographical location, topography, latitude and other reasons. Please give an example for reference ~

Fire wind, sunset wind, flaming mountain, crazy dog wave, etc ~

1. Foehn (also known as Foehn), Taitung is located on the leeward side of the west wind, and the air in South China is humid, stretching for more than 3,000 meters in the north-south direction of Taiwan Province Province.

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

Over mountains and mountains, through adiabatic compression process, abnormal temperature rise occurs, forming the so-called fire wind.

2. Downhill wind ~ dive along the slope.

The high mountains in Taiwan Province Province extend from north to south to the peninsula, and the south of Fangshan Mountain is relatively low, all of which are below 1 000m.

Due to the thick easterly layer, it can cross the southern end of alpine mountains and descend along the slope on the west side of the valley, in Fangshan, Fenggang and Hengchun.

Causing a strong downhill wind, which is called downhill wind locally. During the downhill wind, the temperature in Changchun not only did not rise, but fell.

It is completely different from the cause of fire and wind.

3. The boundary between the flaming mountain and the sunny rain.

The Sanyi area of Miaoli is often shrouded in mist. However, as soon as we crossed the flaming mountain and descended to Daanxi Bridge, the sun suddenly appeared and the blue sky appeared in front of us.

The weather is so different just across a mountain. It is because the northeast monsoon of cold and humid air in winter is influenced by the northeast of Taiwan Province Province.

The mountains above 2000 meters above sea level are blocked by snow-capped mountains, and the area around Flame Mountain (about 600 meters above sea level) is a spent force.

Unless the northeast monsoon is extremely deep, generally due to the topographic effect, low-level clouds and topographic precipitation are generated on the windward side, which is not easy to be affected by mountains.

Taichung area. Therefore, the Flame Mountain has become a natural dividing line, and the natural scenes in the south and north directions of the mountain are different.

4. Crazy dog waves ~ sudden

Sudden waves often appear along the northern coast of Taiwan Province Province before the cold wave in winter, the prevailing monsoon in northeast China or the arrival of typhoon in summer.

There were three big waves at a time, lasting about 2 or 3 minutes, and then calmed down. After a while, the waves suddenly rose again, like a mad dog.

Therefore, local fishermen call it "crazy dog waves".

Because this phenomenon happened unexpectedly, there was no obvious warning in advance, and inexperienced people were fishing at the seaside. When this sudden wave hits,

Often swallowed up by huge waves because they can't escape. There is a theory that the cause of mad dog wave is related to the long wave excited by air pressure.

Long waves travel fast and reach the coast. As the bottom of the coast becomes shallow, the amplitude of wave height doubles. However, the real reason remains to be further studied.
