The grass and trees know that spring will return soon.
All kinds of red and purple fighting fangfei.
Life, spring breeze everywhere.
The grass is green, and the wood is thriving.
Just last Friday we said goodbye to February.
ushered in a thriving March.
March is coming.
Although it is not enough to take off winter clothes and change into spring skirts.
But when everything is rushing towards the season of recovery.
Everything is as loose and bright as spring.
Of course, I still have to remind everyone.
In early spring, there is a large temperature difference between morning and evening.
The battle between cold and warm air currents has not stopped.
Cold air will affect our country.
Temperatures fluctuate in the central and eastern regions.
Precipitation increases. Yesterday (March 3), rain and snow were scarce in most parts of our country, and heavy snowfall occurred in many places. Monitoring shows that from 8 a.m. on March 3 to 6 a.m. on March 4, moderate to heavy snow occurred in the southwest, and there was local heavy snowfall in Nyalam.
Today (March 4), there will be light to moderate snow or sleet in parts of southern Xinjiang, northern and eastern Xinjiang, southern Qinghai, southwestern Gansu, northern Shaanxi, central Inner Mongolia, central and northern Shanxi, northern Hebei, and central and northern Beijing, and heavy to heavy snowfall in parts of southeastern and other places; There are heavy to heavy rains in southern Anhui, southern Jiangsu, Shanghai, northern Jiangxi, and central and northern Zhejiang. 
Tomorrow (March 5), there will be light to moderate snow or sleet in parts of the southeast, central and northern Qinghai, northern Sichuan Plateau, central and northern Shanxi, central and northern Hebei, and central and northern Beijing, among which, there will be heavy to heavy snow in parts of the southeast. There was light to moderate rain in some areas of the Sichuan Basin, southern North China, eastern Huanghuai, Jianghuai, most of Jianghan, Jiangnan, and northern South China, among which, there was heavy rain in some areas of northeast Jiangxi and western Zhejiang. 
In terms of temperature, yesterday (March 3), most parts of China continued to warm up, especially in Jiangnan, South China and other places. Three days from today (4-6), under the influence of cold air, most of the central and eastern regions have 4 to 6 cooling from west to east, and the drop in Jiangnan, South China and other places can reach 8 to 10. From the perspective of the impact period, on March 4, the cold air mainly affected the northwest region, reached Jiangnan in the afternoon of March 5, and began to affect South China in the early morning of March 6.
On March 4, before the main body of cold air moved south, many places in the south continued to heat up, and the maximum temperature of 20 line will be lifted north to the north of Jiangnan, and the local area in South China will hit 30, experiencing the "advanced version of summer". On March 5, as the main body of cold air moves south, many places in the south will cool down, and the temperature will rise and fall like a roller coaster.
Reminder that the cold air is about to affect our country, and the public needs to pay attention to temperature changes in time, add clothes in a timely manner, do a good job of keeping warm, and pay attention to physical health.
In spring, the face of the child changes three times a day. "Colds, allergies, arthritis......All of them have entered a period of high incidence. How to deal with spring dryness, how to "spring cover" to prevent spring cold?
Spring is in the period of atmospheric circulation adjustment.
Warm and cold air activity is frequent.
In addition to the large range of temperature changes.
Windy weather is another characteristic.
Windy weather
In spring, the cold and warm air forces are equal, and they are all active, so windy weather often occurs, especially in the northern part of our country, which is characterized by alternating north and south gales, and the wind is stronger. Generally speaking, the phenomenon of frequent north-south gales can only improve after May. Persistent high winds can cause great harm to transportation, water transportation, and facility agriculture.endThere is a "risk" in traveling on a windy day, cars, ships, trains, airplanes, sea, land and air travel all depend on the "face" of the wind, and everyone walks is also "frightening step by step"!
What do I need to pay attention to when traveling?
Windy weather not only brings inconvenience to travel, but also increases the fire hazard. High winds help the fire spread, and it also allows the fire source to get enough oxygen** to accelerate burning. Life safety is no trivial matter, and the fire alarm bell should ring for a long time!
