"El Nino" and "La Nina" belong to the natural phenomena of the earth. Why do they appear alternately?

El Nino and La Nina are natural phenomena of the earth. Although in meteorological science, we usually define these two phenomena as "abnormal" events, but these two phenomena are beyond human intervention. Only the earth itself can form these two phenomena and complete their alternation.

Regarding the specific performance of El Nino and La Nina, this topic will not be discussed too much, but only why they appear alternately. Usually, El Nino is always staged first, because El Nino is an abnormal climate phenomenon in the process of atmospheric circulation, and the trade winds lead to drastic changes in seawater temperature in the eastern and western equatorial Pacific, resulting in a strong pressure difference.

Its foundation must be based on the earth's normal circulation and trade winds, otherwise there will be no difference in seawater temperature between the east and the west of the Pacific Ocean. La Nina is a correction of El Ni? o, because when El Ni? o occurs, the climate characteristics of the Pacific Rim continent are contrary to the normal climate cycle of the earth (which can be understood as conflict), so the earth can only recover itself once, and this process of self-recovery is La Nina.

This concept is so general that it may be difficult for most people to understand. Let's change it. We can compare the earth to expressway, and compare the meteorological cycle to a car. Under normal circumstances, the earth's meteorological cycle is like a motor vehicle, driving in an orderly way on the expressway, but when the road is bumpy or the driver accidentally turns the steering wheel, the vehicle will deviate.

The "deviation" here can be understood as El Nino, and the "deviation" must be based on the movement of the vehicle (meteorological cycle). When the vehicle deviates, the driver must correct it by various methods to make the vehicle return to the normal path. This correction process can be understood as La Nina. The difference is that vehicle correction belongs to human manipulation, while meteorological correction belongs to the natural behavior of the earth.

Of course, the earth's meteorological system itself is a very complicated subject. El Nino and La Nina are "abnormal phenomena" in the meteorological system, so the factors involved are very complicated and cannot be explained clearly in a few words. The examples in this paper are just for your understanding. In fact, it is impossible for non-meteorologists to study meteorological systems, even El Nino and La Nina.
