What kind of strange weather is Haizi How is it different from a mirage?
According to the statistics of the world's marine historical materials, the turn of spring and summer is the frequent occurrence period of "mirage". Marine markets often appear in the oceans and coastal areas of the world. Peng Cai in China and Yokohama in Japan belong to mirage-prone areas. At the turn of spring and summer from 65438 to 0988, due to the abnormal weather and sea conditions, many sea wonders appeared in the waters near miaodao islands opposite Peng Caige. Some newspapers, radio stations and TV stations reported the wonders of a mirage. After detailed comparative analysis by scientists, it is identified that the various wonders that appeared this year are not really "mirage", but another kind of sea scenery wonder-Haizi. The difference between "mirage" and "Haizi" is that one is far and one is near, and the other is virtual and real. The London scenery thousands of miles away appears over the desert or the East China Sea, which is a "mirage". It is Haizi who reproduces the scenery of the island on the island. The formation principle of mirage and Haizi landscape is essentially different. When the scenery in different places is refracted by sunlight to the high altitude with thin air, it just creates a suitable angle, and then it is refracted back to the low altitude through the transmission of air layers with different densities, and the calm sea surface becomes the ground receiving station of "sea city". Therefore, a mirage is a virtual image from different places. The scenery of Haizi is taken from a local entity on the sea. When there is a big difference between the water temperature and the air temperature, and the inversion of the air layer on the sea surface is strong, a dense "crystal air layer" is generated on the low-altitude sea surface, and then it is refracted by sunlight to form Haizi. In order to further illustrate the difference between a mirage and Haizi, scientists made a detailed analysis of the wonderful island in the afternoon of1June 65438+June 65438+July 07, 988. That afternoon, the weather was clear, the wind direction was northeast, the wind force was 2-3, the air pressure was10/5.5 mbar, the temperature was 24.4℃, the sea surface temperature was 17℃, the visibility was high, and the difference between water temperature and air temperature was 7℃, which provided the background conditions for the formation of Haizi. At the same time, because the waters around miaodao islands coincide with the "advection fog" flowing through it, this light fog belt is intermittent and the flow speed is slow. When Haizi appeared, looking north from the observation point centered on Penglai Pavilion, you can see that there are more than 10 islands arranged horizontally on the sea surface from Daheishan Island in the west to Dazhushan Island in the east for nearly a hundred miles. These images are constantly deformed under the influence of fog flow. Although its landscape is peculiar and extraordinary, it is also the landscape of this hundreds of miles long island, which is no different. Especially the eight-story silver fan mansion on the island, chimneys, tower cranes and other things are very clear, and people on the island know at a glance that it is the scenery of the county where they live. So this is clearly the deformation and displacement of local things, and it is the standard spectacle of Haizi. Scientists believe that all these facts, together with the refraction caused by the earth's rotation and revolution, were carried out in a short time. Therefore, most of the wonders of mirage are fleeting, and the sea view of Temple Island has been displayed for 4 hours and 40 minutes. Therefore, it is believed that this is a scene created by Haizi with the help of "advection fog". Stone Sea, Haizi and advection fog are three natural landscapes on the sea, which can give people illusory and confusing beauty enjoyment.
