Follow the footsteps of spring, explain the text, read the original text and answer.

In the vast land of China, there is a long journey from south to north every spring! The following is the explanatory text of "Follow the footsteps of spring" that I compiled for you. Read the original text and the answers. Let's have a look.

Follow the footsteps of spring. Read the original? Looking forward to, looking forward to, the east wind is coming, and the pace of spring is approaching. Spring has its own hometown like everyone else? That's the south of China. In the vast land of China, there is a long journey from south to north every spring! Before we start our journey in the footsteps of spring, let's make clear what the standard of spring is.

2 solar terms? The beginning of spring? Does not mean the arrival of spring. The twenty-four solar terms were determined by the ancients according to the climate of the middle and lower reaches of the Yellow River at that time. The climate has changed a long time ago. Besides, China is so big that it doesn't snow at all in some places in the south of China. So the 24 solar terms are not uniform. The beginning of spring? Solar terms are not the time for spring.

The scientific standard of spring is: the average temperature every five days, also called weather temperature, is stable between 10℃ ~ 22℃, and spring is coming to us. The average temperature is lower than 10℃ every five days in winter and higher than 22℃ in summer.

(4) Every year in late February, spring strides, starting from my hometown of South China and heading north. It will arrive in Changsha around March 5th, Wuhan, Nanchang and Hangzhou around 15, Zhengzhou and Jinan around 25th, Shijiazhuang, Dezhou and Tianjin in early April, and Beijing around 10 in April. * * * walked for more than 40 days, with a distance of more than 1700 kilometers. It's really rain or shine, day and night!

⑤ After a short stay in spring, go north, arrive in Shenyang around April 25th, and arrive in Harbin around May 10. This road is uphill, so walk slowly. If there is a cold current, there will be some adjustments in the spring schedule.

There are two secrets to the journey in spring. First of all, the speed of climbing mountains is very slow. Some mountains never stop in spring. The higher the terrain, the lower the temperature. Some people can't figure out why the hot air is rising and the temperature is very low when the sky is close to the sun. This is because the energy of the sun does not directly heat the air. When the sun shines on the earth, it heats the ground first and then the air from the ground, so the temperature changes depending on the distance from the ground (heat source). Generally, in the troposphere, the temperature will drop by 0.6℃ for every increase of 100m, and the higher it is, the lower it will be.

Another secret related to spring is that it will arrive at the seaside later, but once it arrives, it will wander there. That's because the temperature of the sea water changes slowly, and with the influence of the sea breeze blowing around, the temperature changes slowly, so the spring will come later, but the stop time will be longer. This is the main reason why some mountains and coasts are often summer resorts.
