It snows in the Sahara and the desert is covered with snow. Why is the local weather so abnormal? Recently, there was another snowstorm in the Sahara desert, which is the biggest snow in local memory ... The thickest snow in the desert is waist deep, and the snow is close to one meter ... Can you imagine that this snow-covered land is actually Africa ... It rarely snows in the Sahara desert, mainly because of local climate factors, not the early warning of climate change. When the temperature suddenly drops to MINUS 2 degrees, rare snowflakes float. This is because after a century of precipitation, the desert is slowly changing. Meteorologist Eric Lester said that although it rarely snows in this area, it is not completely impossible. Snow fell in the Sahara desert, reaching a record high temperature of 58℃. Wu Xiuchen, a teacher from the School of Resources of Beijing Normal University, told the Changjiang Daily reporter: Snowfall in the desert exists, but it is extremely rare. "Snowfall in the Sahara is even rarer. Violent westerly wind fluctuations let us see snow in the hottest place in the world! "

In fact, it has snowed in the Sahara desert in the past. 1February, 979, the first snow in the Sahara lasted only half an hour. 20 16 12 19, the Sahara desert photographed by a photographer snowed all day. 202 1 1 18 In this year, the temperature in the Sahara desert plummeted and it snowed again. Therefore, the snow scene in Sahara is mainly due to long-term local climate change and low temperature formation, rather than the overall climate change warning, so there is no need to panic. The weather is a bit abnormal this year. At the hottest time in Australia, the United States was in the coldest ocean current in history, and even the Sahara desert was snowing heavily. This kind of global extreme weather has hardly happened in modern times, and the global environment may have deteriorated extremely. This extreme weather reminds us to be kind to the environment, otherwise the environment will be rewarded by unbearable disasters, and it is urgent to protect the environment.
