The 2023 national spring progress map is released, let's see where spring is coming

Yesterday (February 24) was the second day of the "August 9th" and the wild geese returned, and spring was in the air. At present, many places in the south are blooming, and the frozen rivers in the north are beginning to melt. However, cold air still frequently affects our country, and many netizens complain that their dressing rhythm has been disrupted. China Weather Network has launched a national spring progress map to see where the footsteps of spring are.

China Weather Network meteorological analyst Shi Yan said that although cold fronts have appeared frequently in my country since February, they are not strong and the temperature in most areas is generally high. Especially in the north, during the intervals of cold fronts, the sun "came on duty" and the temperature rose rapidly. Yesterday afternoon, the temperature in Beijing, Shijiazhuang and other places reached double digits, and the body felt warm.

As the saying goes, "Wild geese come in August and September." At this time of year, spring returns to the earth and life begins to bloom. The geese that migrated south for the winter gradually return to the north. So has spring really arrived in the north? According to the 2023 Spring Progress Map released by China Weather Network, as of now, spring has arrived in southern Zhejiang, southern Jiangxi, southern Hunan, northern Guangxi, southern Guizhou, southeastern Sichuan, and Chongqing. In most areas of Jiangnan and north of it, although spring has begun to bloom, it is still some distance away from real spring.

Generally speaking, in late February, most of my country is still in winter, and in March, spring will rapidly advance northward. The Jiangnan and Jianghuai areas generally enter the meteorological spring in March, while the more northerly areas such as North China and Huanghuai will have to wait until the end of March to early April to welcome the real spring.

Two cold fronts will successively affect my country in the next 10 days, but the intensity is still relatively weak, and the temperature in most areas will rise in fluctuations. Shi Yan introduced that during the interval of cold fronts, most of the central and eastern parts of China will feel warm, but because the real spring has not yet arrived, the temperature in many places in the north will fluctuate. For example, the highest temperature in Shenyang on February 25 was 4℃, and it will rise to 12℃ on the 27th, but it will drop to 4℃ on March 1st. The temperature is like a roller coaster, so don't rush to put away your thick clothes.

China Weather Network reminds that it is already spring in southern China. The temperature difference between day and night in many places in Guangdong and Guangxi can reach more than 10℃. The public still needs to "cover up" appropriately when traveling, adopt a strategy of wearing thin clothes on the top and thick clothes on the bottom, and pay attention to keeping the legs and feet warm. In the Jiangnan and Jianghuai areas, spring is also approaching, but it will still be affected by the cold air from the south. The warmth of spring is intermittent, so it is better to adopt the onion-style dressing method when traveling. In the areas north of the Yangtze River, although there is spring, it is still far from real spring, and it will take some time for winter clothes to be offline.

Note: The spring entry standard is based on the People's Republic of China Meteorological Industry Standard "Climate Season Division". The 5-day sliding mean temperature is calculated based on the temperature sequence of the year to form a sliding mean temperature sequence. When the sliding mean temperature sequence is greater than or equal to 10℃ for 5 consecutive days, the first date in the corresponding temperature sequence of the year that is greater than or equal to 10℃ is used as the starting date of spring. If the initially judged starting date is more than 15 days earlier than usual, a secondary judgment of the starting date is required.
