The "water city" Venice is no longer beautiful. What causes the water city to be short of water?

The water level of the ancient Italian city of Venice, known as the "Water City", has dropped significantly, causing a rare water shortage. Many inland rivers have dried up and become muddy. The main local means of transportation is gondolas. ?One after another stranded on the shore. The water level of the river in Venice, Italy has dropped significantly, and the river bed has dried up. Netizens can't help but sigh that the "water city" has dried up! Hu Xiao, chief analyst of China Weather Network, said that there are three reasons for the exposed dry riverbed in Venice, which are the result of the combined effects of marine activities, weather, and climate change.

According to @CCTV.com, the water level in the ancient Italian city of Venice has dropped significantly recently, and a rare water shortage has occurred. Many inland rivers have dried up, and the main local means of transportation? Gondolas? have been stranded on the shore. On the other hand, the current average water level in Venice's inland rivers is -0.35 meters above sea level. Water City? Why is Venice experiencing drought? Hu Xiao, chief meteorological analyst of China Weather Network, said that first of all, in terms of weather situation, since March, a huge warm high pressure has controlled the entire Italy. Under the influence of high pressure, low water levels are prone to occur. Generally, one atmospheric pressure affects 1 centimeter of sea level. Continuous high pressure causes the pressure of the atmosphere on the sea level to increase, and the sea level decreases accordingly.

Since the beginning of this year, precipitation in Europe has shown a pattern of more in the east and less in the west. Italy, located in central and southern Europe, has received less precipitation. For Venice, February is the month with the least precipitation in the whole year. This year, the situation is very rare. The local precipitation in February this year was only 3.4 millimeters, which is unusually less than the 50 millimeters in February. , which also leads to insufficient river recharge. The most important factor is the tide. Venice is located by the sea (the Adriatic Sea), and its water level is greatly affected by the tides. When the sea level rises, the water level is high; when the sea level falls, the water level is low. This has been fully reflected in several droughts and floods, and only then did the Moses Plan (building dams on lagoons to block ocean tides) come into operation in 2018. Around the first and fifteenth day of the lunar calendar, the tidal activity is most obvious, and the tidal level difference is also the largest at this time. As can be seen from the two tide timetables below, compared with February 28 (the sixteenth day of the lunar calendar) and February 19 (the seventh day of the lunar calendar), the tidal difference is obviously larger, and the water level during the low tide period is also lower. Without the supply of sea water, Shuicheng will inevitably cry out for thirst. The crisis has affected residents' travel and Venice's thriving tourism industry.
