It snows in Africa, but seldom in Cameroon near the equator. What is the reason for this scene?

1. The reason why it snows in Cameroon near the equator may be that the global climate has changed greatly in recent years. As far as snowfall is concerned, its formation is closely related to low temperature. Water from the ground and ocean will become steam and rise into the air when heated, and then these steam will become rain or snow (or hail) when it meets cold air. Whether it is rain or snow (or hail), it belongs to precipitation, but the former is liquid and the latter is solid. Generally speaking, the water vapor in the air will only return to the ground in the form of solid precipitation when the temperature is low, which is why most snowfall weather occurs in winter.

Second, due to environmental pollution, the global climate has also changed greatly in recent years, and some extreme abnormal weather has begun to appear. Snowfall in Cameroon is one of them. Cameroon is located in central and western Africa. Because Africa straddles the equator, the overall climate is very hot and dry, so people also call it "tropical continent". Cameroon's geographical position is very close to the equator, so the climate of this country is mainly tropical, and the average annual temperature is generally maintained at around 24℃. As far as the temperature is concerned, it is difficult to form snowfall in Cameroon. But not long ago, news of snowfall came from Cameroon.

3. It is reported that the place where Cameroon welcomes snowfall is Bana, Haute Encan province in the west. Not only has it snowed here, but the amount of snow is not small, because as can be seen from the relevant videos, there is snow on the roads in this area. Barna residents are also very excited after seeing the snowfall. Many people ran into the snow and began to play with it. Interestingly, a Cameroonian man was still wearing a vest and slippers when playing with snow. It is estimated that these Cameroonians should be as excited as southerners in China when they see the snowfall. Although this snowfall has brought a lot of joy to Cameroonians, it has also aroused public concern about global climate change.

Fourthly, in Cameroon near the equator, it is undoubtedly very rare to see snowfall. But now this rare weather has appeared, and the appearance of this weather is definitely inextricably linked with global climate change in recent years. At the same time, the appearance of this rare weather in turn shows to mankind that the global climate is undergoing drastic changes. In fact, this snowfall not only brought joy to Cameroon, but also caused losses to many local crops. In addition, the local traffic has also been greatly affected.

If it wants to snow, there must be water vapor first. In terms of climate, Cameroon's rainforests are full of water vapor. Moreover, the temperature should be low enough, and it is entirely possible to form snowflakes at high altitude. But in the process of falling, with the decrease of height, the temperature will generally rise. For tropical Cameroon, the surface temperature is not lower than 20℃ all the year round, and there is no temperature condition for snowfall at all.
