Venice, the "water city", is no longer beautiful. What caused the water shortage in Shuicheng?

Known? Shuicheng? The water level in Venice, the ancient city of Italy, dropped sharply, and there was a rare phenomenon of water shortage. Many inland rivers are dry and muddy, and the local main means of transportation? Gondola ship? Stranded on the shore. The water level of the river in Venice, Italy has dropped sharply, and the riverbed has dried up. Netizens can't help but sigh? Shuicheng? I can't believe it! Hu Xiao, chief analyst of China Weather Network, said that there are three reasons for the exposure of Venetian dry riverbed, which are the superposition of marine activities, weather and climate change.

According to @ CCTV. The water level in Venice, the ancient city of Italy, has dropped sharply recently, and there has been a rare phenomenon of water shortage. Many inland rivers have dried up, and the main local means of transportation? Gondola ship? Stranded on the shore, the current average water level of Venice inland river is -0.35 meters above sea level.

Shuicheng? Why is Venice dry? Hu Xiao, chief meteorologist of China Weather Network, said, first of all, judging from the weather situation, a huge warm high pressure has controlled the whole Italy since March, and under the influence of high pressure, it is easy to have a low water level. Generally, an atmospheric pressure affects the sea level 1 cm, and the continuous high pressure causes the atmospheric pressure on the sea level to increase, and the sea level will decrease accordingly.

Since the beginning of this year, the precipitation in Europe has shown a pattern of less in the east and more in the west, and the precipitation in Italy, which is located in central and southern Europe, is even less. For Venice, February is the month with the least precipitation in the whole year, but this year's situation is very rare. The local precipitation in February this year was only 3.4 mm, which was unusually small compared with 50 mm in February all the year round, which also led to insufficient river recharge. The most important factor is the tide. Venice is near the sea (Adriatic Sea), and the water level is greatly affected by the tides. When the sea level rises, the water level will be high, and when the sea level falls, the water level will be low. This was fully reflected in several droughts and floods, and it was not until 20 18 that Moses plan was implemented (damming the lagoon to keep out the tide). Around the first and fifteenth day of the lunar calendar, the tidal activity is the most obvious period, and the tidal level difference is also the biggest. As can be seen from the following two tidal schedules, compared with February 28th (the 16th day of the first lunar month) and February 19 (the 7th day of the seventh lunar month), the obvious tidal range is larger, and the water level in the low tide period is lower. Sea water supply is insufficient, Shuicheng? This is inevitable, too thirsty? Yes This crisis has affected residents' travel and Venice's prosperous tourism.
