The relationship between altitude and air temperature, and between altitude and air temperature

On the same isobaric surface, the higher the altitude, the lower the temperature.

1. The relationship between altitude and temperature is as follows: for every 100 meters above sea level, the temperature drops by degrees Celsius. This is because as the altitude increases, the air pressure will become lower, the air will become thinner, the long-wave reflection on the ground will absorb less, and the temperature will also drop Lingzhou orange low.

2. Expansion: In the near-surface atmosphere (troposphere) anywhere, the air temperature decreases with the increase of altitude - because the heat source of the air temperature is the ground.

Generally, for every 100 meters above sea level, the temperature drops by 0 6 degrees Celsius.

Take the main peak of Fenghuang Mountain in Chaozhou as an example, the altitude is about 1500 meters, if the temperature in the urban plain area is 30, then the main peak will drop 1500 100 0 6 9, about only 21.

Therefore, when climbing the mountain, you should prepare clothes to avoid physical discomfort caused by cooling.

The relationship between altitude and air temperature is as follows:

Typically, the relationship between temperature and altitude is that the higher the altitude, the lower the temperature. Because the main direct source of heat in the tropospheric atmosphere is the ground, the farther away from the ground, the less ground radiation is obtained, and the lower the temperature. For every 100 meters of ascent, the temperature drops by degrees Celsius.

The relationship between air temperature and altitude is t=20-(6*h).

For every 1 km increase, the temperature drops by 6, then the temperature at 1 km is 20-6=14

At an altitude of 2 km, the temperature is 20-6 2=8

Therefore, at a height of h (km), the temperature t = 20-6h

Anywhere in the near-surface atmosphere (troposphere), the air temperature decreases with altitude because the heat source of the air temperature is the ground.

In general, the air temperature also decreases with altitude; The higher it is, the colder it gets. At the same level, air pressure is negatively correlated with air temperature. On the same level, the relatively hot places are low pressure and the relatively cold places are high pressure.

There are exceptions, for example, in the subpolar region, because the cold and warm air currents meet, the air flow rises, but forms low pressure, and the area where the subtropical high is located due to the accumulation of high air pressure, causing the air flow to sink, but instead forming high pressure in the hot place, which is formed by dynamic reasons.

Relationship between barometric pressure and altitude:

The value of air pressure at any place decreases with altitude – air pressure is the atmospheric pressure acting on a unit area, which is numerically equal to the gravitational force exerted on a vertical column of air per unit area.

Altitude refers to the vertical distance above or below the sea level of a certain place or geographical thing on the ground, which is the abbreviation of altitude, such as the higher the altitude, the thinner the air, the lower the air pressure, and the boiling point of water in this place is reduced.

At high altitudes, if you need to cook food, because the air pressure is low, you need to use a pressure cooker and other utensils to cook, otherwise the water will not boil and the food will not be cooked.

For every 100 meters of elevation, the temperature drops;Conversely, for every 100 meters of elevation drop, the temperature rises.

For every 100 meters of rise, the temperature drops.

If there are no other conditions, this calculation will be followed.

For every 100 meters of rise, the temperature drops.

Generally speaking, this can only be an approximate algorithm, because temperature is affected by many factors.

For every 100 meters of rise, the temperature drops. Every kilometer of elevation gain. The temperature dropped by 6 degrees Celsius.

Every kilometer of elevation gain. The temperature dropped by 6 degrees Celsius.

As the altitude increases, so does the temperature.

For every 100 meters above sea level, the temperature drops by degrees Celsius for every 100 meters above sea level. The main direct source of heat in the tropospheric atmosphere is the ground, and the higher the altitude, the farther it is from the ground, the less ground radiation it gets, and the lower the temperature.

Altitude increase has an effect not only on temperature, but also on atmospheric pressure. The higher the altitude, the lower the atmospheric pressure. As a result, there will be some high-altitude areas where food cannot be heated.

Altitude and temperature have four major effects on electrical appliances

The influence of altitude on electrical insulation is generally more than 200 meters above sea level has an impact on electrical appliances, mainly: the altitude increases, the air density decreases, and the heat dissipation conditions deteriorate, so the product should be used in a reduced capacity, and the operating system should be strengthened. The air density is reduced, the compressive strength is reduced, and the rated voltage and insulation voltage of the product are reduced under the condition that the creepage distance and electrical clearance remain unchanged.

The air density is reduced, the ability of the product to withstand overvoltage is reduced, the arc extinguishing ability is reduced, and the breaking capacity of the product is reduced.

The four effects are: the effect on the strength of the insulating medium;Effect on clearance breakdown voltage;Effect of corona and discharge voltage;Effect on the arc extinguishing performance of switching appliances.
