In the past few days, the temperature in various parts of the mainland has soared, and the theme of the weather is a big warmth. Unlike what everyone thinks, this time the warm-up north comes first. Since late February, the temperature in extremely cold Eastern Siberia has suddenly skyrocketed, rising by 30 degrees in some areas in one day. Subsequently, on February 27, the northeast of the mainland also warmed up sharply, Mohe returned to above zero after 108 days, and Qitaihe, Xinlin and other places broke the highest record in February.

To what extent this wave of warming in the north is rampant, that is, the powerful wave of 228 cold air, can not stop the warming momentum in the west, the impact is almost limited to the northeast Inner Mongolia and the eastern coast, on the morning of March 3, the Yangtze River Delta large-scale sub-zero is the swan song of the impact of 228 cold air on the mainland.

After 228 cold air, the heating mass began to release itself without a bottom line, and the temperature of the whole country soared like a wild horse. On March 3, temperatures in 11 provincial capitals or municipalities across the country hit a new high for the year, including Beijing, Zhengzhou, Shijiazhuang, Xi'an, and 10 degrees for the first time this year, and Hohhot for the first time. On March 4, the warming was even stronger, with 16 provincial capital-level cities across the country experiencing the highest temperature in the year, including Jinan, Chengdu, Nanjing exceeding 20 degrees for the first time, and Changchun exceeding 10 degrees for the first time; Not only the temperature in the north remains high, but the Yangtze River basin has also joined the ranks of record highs.

This next wave of strong warming will continue throughout early March, and most of the country will be sunny and dry, with a huge temperature difference between day and night, except for the rainy southwest. Especially in North China and the Central Plains, temperatures will reach their highest point on March 9-10, when temperatures in Hebei, Shandong and Henan may hit the highest records in the first half of the year, and Shijiazhuang may even experience the earliest 30 degrees in history.

Spring in the meteorological sense will also quickly advance from Jiangnan to North and Northwest China, Hangzhou has entered spring, Shanghai has recently entered spring without suspense, Beijing and Shijiazhuang are expected to hit the earliest spring record in history. In the afternoon of sunshine, it is possible to taste early in the south and north at the end of early March and experience the feeling of summer.

But there are three things that need to be reminded of everyone. First, although the temperature is rising rapidly during the day, but the night has not kept up with the warming rhythm, the temperature difference in the north is generally 15-20 degrees, or even more than 20 degrees, such as Heilongjiang Huzhong 3-day temperature difference as high as 30.7 degrees, Yinchuan 4-day temperature difference of more than 20 degrees. In addition to the southwest, the temperature difference in most of the south is also 10-15 degrees. In such weather, it is very easy to catch a cold. In addition, the "spring dryness" in this big warm-up is quite serious, on the afternoon of the 3rd, the relative humidity of Beijing Shijiazhuang Zhengzhou Yinchuan is less than 10%, Nanjing Wuhan is less than 30%, Qinghai Duran is only 3%, static electricity crackles, and there is almost no drop of water in the air. Such dry weather will also make the mucous membranes of the respiratory tract more fragile, giving various viruses an opportunity to catch a cold.

Third, and very familiar to everyone, after an unusually warm scene, strong cold air will move south in mid-March, which may bring the first cold wave of the spring. Such a big change in warmth and cold is also easy to make people cold. There are three cold prone factors superimposed, the recent cold risk is very large, definitely not less than midwinter, but also please prepare spring, summer, autumn and winter clothes, extremely flexible increase and decrease, protect the respiratory tract, strictly prevent colds.
Just when the temperature on the mainland skyrocketed, the temperature trend in the United States on the other side of the ocean was completely opposite to that of the mainland. Continuous strong cold air and low eddies of the Pacific Ocean swept through most of the United States from west to east, and thick snow covered the desert in Arizona except California. The cold air also collided violently with the warm, humid air of the Gulf of Mexico, and tornado erupted in waves, recording dozens of tornadoes in several states, including Texas and Louisiana. Oklahoma has broken consecutive records for the number of tornadoes in the state in 12, 1, and 2 months.

And in the Southern Hemisphere in late summer, the quiet retreat of the subtropical high triggered a cyclone activity climax. South Pacific sister cyclones Judy and Kevin are moving hand in hand to the southeast, both hitting Vanuatu and its islands with high intensity in just 3 days, causing significant damage. The southern Indian Ocean cyclone Freddy, which has survived for a month, made landfall in Mozambique, stayed for a while, and then suddenly reversed into the sea, and has been revived and is about to strengthen again. Freddy's weak guided air flow will maneuver around the Mozambique Channel for 10 to 20 days, potentially making it the world's longest-lived tropical cyclone on record.
