A vast number of wonders appear in the waters of Qingdao. What is the reason for the formation of this wonder?

There are vast wonders in the Qingdao sea area. Its appearance is mainly due to the dramatic temperature difference between the sea temperature and the air temperature. When dry and cold air blows from the land to the warm and calm sea surface, the sea water evaporates or The volatilization phenomenon intensifies, and the generated water vapor quickly condenses into ice crystals in the cold air, and is then blown into the air by the strong cold wind, forming a "Hai Hao" spectacle of vast smoke waves and floating fairy air. ?

The strong cold air arrived, and the island city instantly fell into the ice cellar. It is understood that the lowest temperature in the urban area on the morning of January 7 was -15.9℃. As of 15:30 pm, the highest daytime temperature on the 7th was -10.6℃ in the urban area, and the highest temperature in other districts and cities was -9.4℃ in the West Coast New District. On that day, a rare "Haihao" spectacle appeared on the sea level along the coast of the island city, adding a magnificent scenery to the island city in winter.

These have broken the lowest temperature extremes at the Qingdao National Basic Weather Station since 1961. In addition to the Qingdao Station, the Huangdao National Meteorological Observatory recorded a minimum temperature of -17.3°C, which also broke the lowest temperature extreme at this station since 1961. Wear more clothes when you go out, your face feels like a knife!? The cold wave is well-deserved, it’s too cold! Early on the morning of the 7th, this cold wave hit Weibo and WeChat Moments. Although the reporter was well prepared and put on thick clothes, he was still instantly frozen by the cold wind as soon as he went out. Within a short while, even the hot breath exhaled from his nostrils turned into ice. As a native of Qingdao, this is the first time this reporter has encountered cold air of this level.

On January 8, the lowest temperature in urban and coastal areas was -14℃~-13℃, and the lowest temperature in inland areas was around -15℃. On the 8th, the highest temperature in the city during the day was -6℃~ -5℃.

On January 9, the minimum temperature in urban and coastal areas was -10℃～-8℃, and the minimum temperature in inland areas was -12℃～-11℃. During the day on the 9th, the minimum temperature in urban and coastal areas was The maximum temperature is around 0℃, and the maximum temperature in inland areas is around -2℃.

On January 10, the lowest temperature in urban and coastal areas was -8℃～-6℃, the lowest temperature in inland areas was around -11℃, and the highest temperature in the city during the day on the 10th was 1℃～2 ℃.

It is very rare for such a spectacular and sustained "Haihao" phenomenon to occur in Qingdao. This phenomenon generally occurs in high-latitude sea areas such as the Sea of ??Japan. ?It’s not that water boils because it heats up, but the difference between sea and air temperatures in thermodynamics and the high wind speed in dynamics, which together cause strong evaporation or volatilization of sea water, as well as the rapid condensation of water vapor and the scattering of ice crystals. . This rapid condensation and dispersion of water vapor is the same principle as splashing hot water in extremely cold places. This phenomenon is particularly majestic and spectacular, and there is an endless stream of local citizens.
