Why doesn't it snow or rain in the northeast for three or nine days?

There is little large-scale rainfall in northeast China in March and September, and the earth's climate is out of control? Analysis: amplify the power of cold wave

65438+1October 13 in the afternoon 13. From the 24-hour temperature change chart, today's strong cold wave has begun to move southward in the central and eastern regions of China. After a sharp cooling in the northwest, today's cooling area has been expanded to Inner Mongolia, Northeast China, North China and other places. Especially in Inner Mongolia, the power of the cold wave has been fully demonstrated here. In many places, there has been a 24-hour, 20-degree "diving" to cool down, which is obviously colder than yesterday.

It rained in the northeast on the first or third day.

For example, in Aershan, Xing 'an League, Inner Mongolia, the monitoring data showed that the highest daytime temperature in Aershan was above zero on June 65438+ 10/2, but in the afternoon of June 65438+13, the temperature in Aershan directly dropped below -20 degrees, which was 20 degrees lower than yesterday.

However, in the northeast plain, the weather here is even weirder before the cold wave moves south-you can see it on the hourly temperature map of 1 this morning. Although it is already early in the morning, most parts of the Northeast Plain remain at zero, and the three provincial capitals of the three northeastern provinces are above zero.

During this period, many Northeasters experienced the first rain in their lives. For example, in Changchun, Jilin Province, precipitation was monitored from 0: 00 am on June 65438+ 10/3, which lasted for four hours. At the same time, the temperature is over 3 degrees, which is a complete rain. This is the first time in the history of meteorological observation in Changchun that it rained on March 9. It's March 9, and it should be ice and snow in the northeast. But it rains at this time, which is quite rare.

Second, the earth's climate is chaotic?

There is no doubt that whether it is zero in the early morning in the northeast or the rare rainfall in March and September, it shows that the degree of warm and humid water vapor in the central and eastern regions of China is quite abnormal, which not only makes the rain and fog hazy in many places in the south, but also makes it flood into the northeast, making the temperature much higher. According to the monitoring data of National Climate Center, during the period of 65438+1October 8-65438+1October 2, the temperature in central and eastern China was obviously higher, and the temperature in Northeast China, Inner Mongolia, northern North China, Jiangnan and other places was higher than 6 degrees in a large range, which is not an exaggeration.

Then some netizens want to ask: Is this the earth's climate chaos? In the short term, the cold wave will go south, and the northeast will experience the most violent cooling after a wide range of abnormally high temperatures. For example, in Changchun, Jilin Province, which seldom rains this morning, the monitoring data show that the temperature has plummeted since the early morning, dropping by about 10 degrees, and the temperature dropped to about -6 degrees this afternoon. In this way, on March 9, this wave of unusually large-scale warm tide in Northeast China came to an end. However, since last autumn, the weather pattern in China has fluctuated in this autumn and winter, which shows that China and even the northern hemisphere are still in an abnormal climate pattern.

Third, it will amplify the power of the cold wave.

It has been mentioned many times in the articles before Zhong Qi 'ai that the strong warm and humid airflow will drive the temperature to be higher, and the temperature will be more intense after the cold wave comes. The same is true in the northeast, where the air has been unusually warm recently. The unusually strong warm and humid air flow will amplify the power of the cold wave. According to the forecast of the Central Meteorological Observatory, after the arrival of the cold wave, the temperature in many places in Northeast China will generally drop by 14- 18 degrees, and the highest cumulative drop may reach 30 degrees.

For example, in Changchun, the official forecast pointed out that after the arrival of the cold wave, the minimum temperature on June 65438+1October 14 will drop to -23 degrees, which is more than 20 degrees lower than that on June 65438+1October/0/2, and the maximum temperature will also drop from 4.5 degrees to-
