The phrase "the east rises and the west falls, and Tao is ruthless and affectionate" describes the weather characteristics.
Step 2 describe precipitation
"Earthworms come to our hall after three days of rain" is the rainy weather in the south of China.
3. Describe the change of temperature
The sentence "it's too cold up there" shows that with the increase of altitude,
People often say that "poems can be recited even if they can't write", so I can say that "there are 300 Tang poems, 30 lyrics and proverbs, and geographical knowledge is self-evident". It can be seen that there are not only a lot of literary knowledge, but also a lot of geographical knowledge in poems, songs and proverbs.
1. It describes the weather and climate.
The sentence "Sunrise in the east and rain in the west, ruthless and affectionate" describes the weather characteristics. Weather is a specific atmospheric condition in a short time, including rain or shine, wind and rain, cold and hot, wind, etc., which generally changes greatly. This sentence shows that the short-term atmospheric changes such as sunny weather at that time, such as "like a strong wind in spring, it blows up at night and blows away the petals of ten thousand pear trees", also describes the weather changes. "The wild sand shore is clean, the sky is crisp and the autumn is crisp" to describe the climate, which is a long-term and stable weather feature of a place and generally does not change much. The main difference between weather and climate is that weather is a short-term and changeable atmospheric condition, while climate is a long-term and stable atmospheric condition.
"Wear fur coat in the morning, wool in the afternoon, and eat watermelon around the stove" describes the temperate continental climate in Xinjiang, China, which is characterized by large daily temperature difference and little precipitation. Every summer, the sun is like fire here, and the temperature rises rapidly during the day, sometimes as high as forty or fifty degrees Celsius. The locals said, "Boil eggs in the sand and bake pancakes with stones." But at night, the temperature dropped sharply, so people had to build a stove to keep warm and taste the freshly picked watermelon around the stove. At the same time, Hami melons in Xinjiang are particularly sweet, which is also the reason. As for the lack of precipitation, the drying room used to make raisins in Turpan is enough to explain.
Step 2 describe precipitation
"Earthworms come to our hall after three days of rain" is the rainy weather in the south of China. In May and June every year, with the gradual strengthening of the summer monsoon, the cold air force in the north is weakened, but it can still affect the area south of the Yangtze River. The cold and warm air masses are in phase here, forming a front. Because it is evenly matched, it forms a quasi-static front and produces continuous precipitation, which lingers in the middle and lower reaches of the Yangtze River for about a month. At this time, it is the time when plums are ripe. In general, the summer monsoon begins to affect the eastern part of China in April and May every year, and the frontal rain formed by the warm air mass from the ocean and the cold air mass from the north is in Nanling area, so there is more precipitation here, that is, "it rains in the Qingming period".
3. Describe the change of temperature
The sentence "it's too cold up there" shows that the temperature gradually decreases with the increase of altitude. Generally speaking, in the troposphere, the temperature drops by 0.6℃ for every rise of 100 m.
These two sentences vividly reflect the vertical change of mountain climate and vegetation and the vertical regional differentiation law of natural belt. The altitude of Dalin Temple in Lushan Mountain is between1100 ~1200m, which is about 6℃ lower than the temperature at the foot of the mountain. The opening time of peach blossoms will naturally be about half a month late. A similar poem: "Four seasons in one mountain, ten miles in different days" is a true portrayal of the vertical change of climate and vegetation in Hengduan Mountain area. "There are four seasons in a year, and there are warm clothes all year round." This ballad vividly reflects the cold climate characteristics of the Qinghai-Tibet Plateau.
The phrase "Peach Blossom Mountain in front of the mountain and snow behind the mountain" describes the influence of slope direction on temperature, which leads to the difference of natural landscape between the north and the south of Qinling Mountains. The southern part of the Qinling Mountains is subtropical evergreen broad-leaved forest and the northern part is temperate deciduous broad-leaved forest, so the natural landscapes on the north and south sides of the Qinling Mountains are completely different.
4. Description of monsoon
"My family lives on a high loess slope, and strong winds blow across the slope, whether it is northwest wind or southeast wind." The song "Loess High Slope" sings the main wind direction in the monsoon region of eastern China. Due to the difference of thermal properties between land and ocean, the seasonal change of air pressure center on land and ocean leads to the regular change of prevailing wind direction with seasons in a year, forming monsoon. In summer, the influence of the North Pacific high is greatly enhanced, forming an Indian low on Eurasia, which is blown to the east of Asia along the western edge of the North Pacific under the pressure gradient force, forming a southeast wind. In winter, on the contrary, the northwest wind is formed, that is, "whether it is northwest wind or southeast wind."
In addition, there are other aspects of geography and the description of Mount Tai: "Once you climb the peek at the top of the mountain, you will see that other mountains are dwarfs under the sky." ; Equatorial region: "Sit on the floor, travel 80,000 miles a day, watch the sky and see thousands of rivers from afar." Describe the rivers and lakes: "Don't you see how the water of the Yellow River moves out of heaven and into the ocean, never to return?" Description of the hills: "The mountains are heavy and the water is heavy, and there is no road to doubt. "In fact, the knowledge in poems and proverbs is all-encompassing and colorful. I just read and understand from a geographical point of view. This is just a drop in the ocean, and more hidden knowledge needs us to explore.
