Why has Venice, known as the "Water City", been troubled by low water levels in recent years?

Venice, known as the "Water City", has been troubled by low water levels in recent years because of: 01. The influence of high pressure over the Adriatic Sea. 02. More cold weather. 03. Tunisia itself has an underdeveloped water system.

01. Venice, the famous water city, now has no water. The water level in Venice was 70 centimeters lower than usual, causing traffic jams in the city's canals and making them unable to operate. Without water, traditional sea vessels can only be stranded, but it is also inconvenient for people to walk because it is full of silt and the exposed river bed is very ugly.

The Adriatic Sea is part of the Mediterranean Sea. It not only belongs to Italy, but also has a great impact on Italy's weather. Because there is a lot of high pressure over the Adriatic Sea, the air will unconsciously flow toward the interior of Italy. Therefore, under the influence of high air pressure, the sinking air will naturally force the temperature to rise and the humidity to decrease, making it difficult to form windy and rainy weather. So Tunisia has less and less water.

02. High pressure and low pressure at sea always exist. Especially in summer and winter, uneven heating of the ocean and land will in turn form high and low pressure at sea. And because Italy is surrounded by the sea on three sides, it is greatly affected by the marine climate. Even though the Alps to the north block some of the cold winter winds, there has been more cold weather recently. Italy has a subtropical Mediterranean climate, and the south of Italy is more susceptible to cold weather.

The cold air is strong and there are more low-temperature weather, which will greatly reduce the precipitation.

03. The water system in Tonis is actually not underdeveloped. If there is no precipitation brought by sea air currents, it can only rely on the largest river, the Mejerda River. The water volume of the Mejerda River in winter is 1500-2500 cubic meters/second, and in summer it directly changes to 4 cubic meters/second. The amount of external water was not enough, and the water flow in the river itself was low, which once caused the river bed to dry up. In recent years, it has been troubled by low water levels.
