By its name, we can understand that it is a very hot wind. It is a phenomenon unique to the mountains, perhaps still unfamiliar to many people in other regions.
Many regions meet hot, windy mountains globally, but the most famous are the Alps in Europe, Mount Lotchi in the Americas, and Caorahu in the former Soviet Union. In days of hot wind in the Alps, the temperature is suddenly higher than 20 ° C, the early spring weather suddenly turns into summer, not only hot but also extremely dry, often causing fires.
It is not responsible for Algeria’s hot monsoon season to implement the regime of light and fire management. The hot wind blows strongly, and the leaves burn dry, the soil is cracked, creating a terrible drought. Sometimes people find it difficult to breathe; their health deteriorates very quickly.
The northern slope of the Anpisx region is the headquarters of the hot wind. Every year, the hot wind takes place over 75 days, the maximum year is 104 days, each wave lasts 8.3 hours, the longest time is 57 hours, if, excluding the stopping time in the middle, the time lasts for nine consecutive days.
Why do hot winds appear in the mountains? The reason is that after the wind overflows the mountain top, the subsidence trend appears. In meteorology, it is known that, when there is a stream of air rising from the ground, for every 1000 m high, the average temperature drops to 6.5 ° C; in contrast, when a gas stream from the top settles. to the ground, every 1000 m low, the average temperature rises 6.5 ° C. That is to say, when the air from the top of the mountain is 4,000-5,000 meters higher than the sea surface, the temperature will rise above 20 ° C, causing the cool climate to heat up suddenly. That is the cause of the hot wind.
The hot wind can sometimes be beneficial for agriculture. Winter snow in the mountains of North America Lotchi very thick, spring thanks to the hot wind, but the snow melts quickly, the ground grows full of green grass, preventing cattle from starving. So the people of that area call the hot wind a snow eater. Light hot winds raise the temperature, allowing corn and fruit to ripen early, so the inhabitants of Caorahu and Tasken in the former Soviet Union called the hot wind the wind of corn and pears. In mid-latitude, Switzerland is a region of strong hot winds, allowing them to plant laurel trees, camellia, and flowerless fruit trees of the sub-tropics. It is also thanks to the merits of the hot wind.
