How to talk about the relationship between isotherm distribution and temperature difference

The low latitudes of the earth have a large solar altitude angle and obtain more heat and high temperatures, while the high latitudes have a small solar altitude angle and obtain less heat and low temperatures, so the isotherm distribution is characterized by the gradual decrease of the isotherm temperature from low latitudes to the poles, and its isotherm is roughly parallel to the latitude

Therefore, the answer is: the degree of isotherm gradually decreases from low latitude to the poles; Roughly parallel

The term isotherm is defined as a line that connects places with equal temperature values at the same time on a plan. It is possible to display the distribution of high and low temperatures.

The term isotherm is defined as a line that connects places with equal temperature values at the same time on a plan. It is possible to display the distribution of high and low temperatures.

Pinyin is: děngwēnxiàn. The phonetic pronunciation is:

One. The structure is: equal (upper and lower structure) temperature (left and right structure) line (left and right structure).

What is the specific interpretation of isotherms, we will introduce you through the following aspects:

1. Citations and explanations [click here to view the details of the plan].

A line formed by connecting places with equal temperature values at the same time on a floor plan. It is possible to display the distribution of high and low temperatures.

2. Chinese dictionary.

The temperature at the same time in various places, after the sea level height is corrected, connects the places with the same air temperature, which is called an isotherm. Isotherm plots can be used to represent the horizontal distribution of air temperatures.

3. Network Explanation.

The isotherm isotherm is the line connecting the points with the same temperature value of Tanchunling on the diagram, which is called an isotherm. 1799 In 1804, the German geographer Humboldt revealed the connection between various phenomena in nature on the basis of extensive investigation of North and South America and the interior of Asia, proposed that the average value of meteorological elements could clarify the climate regularity, and created a cartographic method of using isotherms to represent the average temperature. In 1817 the world's first isotherm map was drawn.

Idioms about isotherms.

Equal to the three of the three and the nine, the same courtesy, the same writings, the same body, the elongated thread, one needle, one line, etc., the rice under the pot, etc., because of this lead, the needle, etc.

Words about isotherms.

It is regarded as waiting for leisure, and waiting for the next and so on, because of this gentleness, such courtesy, and the third class, the nine grids, and the elongated line of leisure, and the writings of the idleness.

Sentence formation about the line of equal letting.

1. A new adsorption isotherm equation is derived from the inhomogeneity of the energy distribution on the surface of the adsorbent, which is simple and conforms to the monolayer adsorption mechanism.

2. A new method for measuring adsorption isotherms in gas chromatography was proposed, and the concentration of gas-solid two-phase components at equilibrium was calculated by using the capacity factors determined under different injection amounts.

3. The isotherms around a tunnel can be understood as the superposition of the original temperature field.

4. With the enhancement of the rigidity and aromaticity of the internal structure of kerogen, the nonlinearity of the adsorption isotherm gradually increases.

5. According to the needs of the analysis of the corrosion trend of the inner wall of the copper converter, an infrared series image registration algorithm based on isotherm profile features was proposed.

(1) If the isotherm protrudes to the low latitude, the temperature is lower than that at the same latitude; If the area is on land, it is: Winter continental, higher terrain; If the area is on the ocean, it is: summer ocean, cold snaps passing through.

2) If the isotherm protrudes towards high latitudes, the temperature is higher than that at the same latitude; If the area is on land, it is: summer land, low-lying terrain; If the area is over the ocean, it is: Winter ocean, warm currents pass through.

3) If the isotherm is straight, it indicates that the underlying surface is single in nature (for example, the isotherm of 400-600 in the southern hemisphere is relatively straight, indicating that the ocean area in this area is large and homogeneous).

4) Areas with closed isotherms that form warm or cold centers due to topography.

The isotherms are dense and the temperature varies greatly; The isotherms are sparse and the difference in temperature is small.

The isotherm protrudes to the high latitude, indicating that the high temperature area is wide. The isotherm protrudes to the low latitude, indicating that the low temperature area is wide.

The isotherm is parallel to the parallel, indicating that the influence of latitude is prominent.

The isotherm runs parallel to the coast, indicating significant influence from the ocean.

The isotherm is parallel to the trend of the mountain range or the edge of the plateau, indicating that it is obviously affected by the topography or has a large vertical change.

The isotherm is a closed curve, and if the temperature in the line is high, it can be judged as a basin; If the temperature in the line is low, it can be judged to be a mountainous area.

1. Describe the direction of the isotherms, such as east-west, northeast-southwest, south-south protrusion, etc., or what direction is in the eastern section, what is the direction in the western section, etc.; and explain its influencing factors, such as latitude, topography, ocean currents.

water bodies, etc. 2. Describe the density of isotherms: dense temperature difference is large, sparse temperature difference is small; And explain the reasons, such as steep terrain, dense isotherms, dense continental isotherms in winter, etc.

The temperature on the isotherm is the same, an isotherm represents a temperature, and the denser the isotherm isotherm is, the higher the frequency of temperature changes in the region, that is, the temperature changes in the region are large, that is, the temperature difference is large. The isotherms are sparse, reflecting that the temperature does not change much, and therefore, the temperature difference is small. That is, the isotherms are dense and the temperature difference is large; The isotherms are sparse and the temperature difference is small.

On the same diagram, the denser the isotherms, the greater the difference in temperature, and the sparser the isotherms, the smaller the difference in temperature.

The sparse isotherm indicates that the distance between the two places is long, and the temperature changes after such a distance, indicating that the temperature difference is small;

On the contrary, if the isotherm is dense, the distance between the two places is close, and the temperature of such a close distance changes, indicating that the temperature difference between the two places is large.
