High School Geography About the Temperature on the Peak of the Mountain .

I didn't learn that much when I learned about the valley wind, so I just analyzed the sea and land winds.

During the day, the sun radiates the ocean and the land, the same radiation heat, because the specific heat of water (physical teaching) is greater than the specific heat of the land, the ocean heats up more slowly, the temperature of the land is higher than that of the ocean during the day, the land is the center of low pressure, and the wind blows from the ocean to the land; In the same way, at night, the ocean cools down slowly due to the greater specific heat of the water, and the ocean temperature is higher than that of the land, which is the center of high pressure, and the wind blows from the land to the ocean.

That's all you need to know :

During the day, the summit is first illuminated by the sun, and the temperature rises rapidly.

The valley at night is due to the topography. The heat dissipation is slow, and the temperature drops slowly.

"Sea breeze" and "land breeze" are related to the different thermal properties of the sea and land.

Because it is a valley bottom, heat is not as easy to dissipate as flat land (atmospheric convection turbulence such as wind on the ground is more significant than that of the valley bottom, and heat is easy to lose), so the temperature in the valley rises more during the day than on flat land, and the temperature rise will cause the air to expand and rise, leading to the formation of convection, and the warm air will rise along the slope to form a valley wind. At night, due to the radiative cooling on the slope, the air near the slope becomes cold rapidly and the density increases, so it slides down the slope and flows into the valley floor to become a mountain wind. To put it simply, the valley floor warms up quickly during the day and cools slowly at night, resulting in the opposite thermodynamic circulation during the day and night.

The formation of sea and land breeze is when the land heats up faster during the day under sunlight (from the specific heat analysis, the specific heat of sea water is greater than that of land, so the sea temperature is slower than that of land, and the cooling is also slower than that of land. Therefore, the rapid warming of the land in summer is the heat source, and the rapid cooling in winter is the cold source), the air temperature on land is higher than that of the sea, the isobaric pressure is inclined to the ocean, and the air flows from the continent to the ocean, so the air quality of the land on the lower ground decreases, and the ground air pressure decreases, and the ocean is increased by the inflow of continental air in the upper layer, and the sea surface pressure increases, so the horizontal pressure gradient force from the ocean to the land is generated in the lower layer to form the sea breeze. At night, the radiation cooling of the land is faster than that of the sea surface, and the cooling and contraction of the air on land causes the upper air pressure to be lower than that of the same height on the sea surface, and the isobaric surface is inclined from the sea to the land, and the ground pressure is higher than the sea surface pressure, so the thermal circulation opposite to that of the day is formed, and the lower wind blows from the land to the sea, forming the land breeze.

This pressure gradient due to the difference between land and sea heat is relatively small and only manifests itself when the horizontal pressure field is weak over a wide area.

In the tropics, the temperature varies greatly from day to day, especially in the coastal areas where cold ocean currents pass, and the sea and land breezes are the most intense, which can occur throughout the year. In temperate regions, the sea and land breezes are weaker and occur mainly in summer.

Daytime. The top of the mountain is irradiated by the sun before the valley, and the temperature rises faster, so the temperature at the top of the mountain is higher than that of the valley, and the air flow at the top of the mountain rises, and the air flow from the valley moves along the slope to the top of the mountain, forming a valley wind.

At night. The heat dissipation at the top of the mountain is faster than that of the valley, so the temperature in the valley is higher than that at the top of the mountain, the air in the valley rises, and the air from the top of the mountain moves towards the valley to replenish the air in the valley, forming a mountain wind.

Summary: Methods of analysis.

1.First, determine the relative cold source and heat source.

The ground is unevenly hot and cold.

2.The analysis is based on the principle of thermal circulation.

Training: Urban style.

Sea and land breeze (because the specific heat of water is greater than that of land, the ocean heats up and cools more slowly than land, and the land temperature is higher during the day than the ocean, and the ocean temperature is higher than that of land at night).

In summer, the temperature in the high mountains decreases with every 100 meters of rise from the base of the mountain.

Temperature can only be measured indirectly by certain characteristics of an object as a function of temperature, and the scale used to measure the temperature value of an object is called a temperature scale. It specifies the starting point (zero point) of the temperature reading and the basic unit for measuring the temperature. The SI unit is the thermodynamic temperature scale (k).

Other temperature scales that are more commonly used internationally are Fahrenheit (°F), Celsius (°C) and the International Practical Temperature Scale.

From the point of view of molecular motion theory, temperature is a sign of the average kinetic energy of the molecular motion of an object. Temperature is the collective manifestation of the thermal motion of a large number of molecules and is statistically significant. For individual molecules, temperature is meaningless.

The degree of heat and coldness measured on one of several arbitrary scales based on an observable phenomenon (e.g., the expansion of a column of mercury).

Basic explanation: The degree of heat and coldness measured on one of several arbitrary scales based on an observable phenomenon (e.g., the expansion of a column of mercury). Temperature is a manifestation of the translational kinetic energy between molecules within an object.

The faster the molecule moves, i.e., the higher the temperature, the hotter the object; The slower the movement of the molecules, i.e., the lower the temperature, the colder the object.

From the perspective of molecular motion theory, temperature is the indicator of the average kinetic energy of the molecular motion of an object, and temperature is the collective manifestation of the thermal motion of the molecule, which is statistically significant.

The temperature is high to a certain extent, the oxygen in the air is burned into flames, and the heat transfer can lead to the melting and melting of the substance, and the melting is so high that it destroys the material (mass) and energy;

The temperature is low enough to a certain extent, it can solidify with water or air or water in the body (blood) to transfer cold, freezing can cause matter to fragment, cold to the extreme, can shatter matter, mass energy, all life-threatening can change the speed of movement (movement) of objects. ）

This is how many 100 meters).

100*17=1700 meters.

The relative height is 1700 meters.

Summittop temperature = ground temperature - (mountain height 100).

According to the title: summit temperature = 24 - (800 100).

Measure the temperature at the foot of the mountain, then at the top of the mountain, and divide the difference between the temperature at the bottom of the mountain and the temperature at the top of the mountain by * 100.

Summittop temperature = ground temperature - (mountain height 100).

That's right!

The temperature of the atmosphere is directly related to the ground, because the atmosphere is mainly warmed by absorbing the long-wave radiation of the ground, and the short-wave radiation of the sun is less absorbed, so the higher the farther away from the ground, the less ground radiation is obtained, and the lower the temperature, at the same time, the atmosphere on the top of the mountain is thin, the heat loss is more, and the wind at high altitude is strong, and the heat exchange between the surrounding air is strong.

As for the temperature, remember: for every 100 meters of altitude gain, the temperature drops by degrees Celsius.

The temperature is pure Luxiang t = 26 °

The mountain does the top temperature of the balancing hand t=
