Rare snowfall in Australia. Why is the weather so abnormal this year?

Because the weather will change with the influence of the environment, for example, the reason for snowfall in winter is the change of climate and weather. A cold front is the intersection of cold and warm air masses. If the cold air mass moves to the warm air mass actively, it will form a cold front, and vice versa. In winter, the continental temperature is lower than the ocean temperature, which forms a strong cold high pressure on the land, and the air flow diverges from the high pressure center to the surrounding areas. The air mass moving to low latitudes is essentially cold air, and a cold front is formed when it meets a warm air mass. When a cold front crosses the border, there will be rain (snow), wind and cold. After crossing the border, the temperature and humidity will drop sharply and the air pressure will rise.

In winter, cold air masses move rapidly to the south from different directions, which often leads to disastrous strong winds, cold weather and even cold waves. Specific analysis, some places will get hot, but some places will sometimes get cold. The greenhouse effect does not mean that the temperature has been rising. In Europe, global warming will show that summer is very hot and winter is very cold. The greenhouse effect will reduce the speed of ocean currents. Winter in Europe is getting colder and colder. 165438+1At the end of October, European countries were hit by snowstorms and cold currents. From Britain to Poland, from Germany to Greece, there will be sudden cooling changes in different degrees.

When the northern hemisphere is still suffering from the summer heat, Australia in the southern hemisphere has become? Ice and snow world? . Since August 10 every year, southeast Australia has been hit by cold air, resulting in very rare heavy snow. This heavy snow will excite kangaroos who have never seen snow before. Recently, some netizens photographed a large group of kangaroos jumping in the snow, and the photos looked very happy.

After the video was uploaded to social networks, it immediately became popular. The netizen who sent the video also commented:? After all, you can't see such a snow scene every day in Australia. Indeed, even though Australia is currently in winter, because most of its areas are located in tropical and subtropical regions, the temperature can still be kept above 10 degrees, and it basically doesn't snow, only some high mountain areas in the south will snow. According to the Australian Meteorological Bureau, the snowfall is unusual, and there will be severe weather such as strong winds and heavy rains on the eastern coastline.
