Does the temperature of the weather have anything to do with the sun?

Question: How is the surface temperature of the sun measured?

Answer: We can't take a thermometer to the sun, so how can we measure the temperature of the sun? We are directly exposed to sunlight, which tells us about the temperature of the sun.

A concave mirror with a diameter of 1 meter is pointed at the sun, and the focus is gradually adjusted, and when a small coin-sized image of the sun is obtained, a piece of metal is placed on the focal point, and the metal sheet is immediately bent and melted. The temperature on the focal point is 3500 degrees Celsius. Therefore, the temperature on the sun will never fall below 3500 degrees Celsius.

Through the analysis of the dialectical relationship between temperature and light, people have gradually grasped the temperature of the sun. The temperature of the sun can be estimated from its color, which is usually seen as golden yellow, and the color of the sun is 6000 degrees Celsius, taking into account the absorption of the earth's atmosphere. The temperature corresponds.

In addition, by measuring the total radiance of the sun, spectroscopic analysis and radio technology, it can also be proved that the temperature on the sun is 6000 degrees Celsius . This, of course, is the surface temperature of the Sun (that is, the temperature of the sun's photosphere as we see it with the naked eye). As for the temperature of the center of the sun, it is estimated to be about 20 million degrees Celsius.

When the sun radiates strongly, the weather becomes hot.

It will cause frequent changes in the weather, which will affect the temperature of the weather, which will affect the formation of the weather, and will also cause the temperature of the weather to drop sharply, which will affect the rise of temperature.

The actual temperature under the sun is more accurate, because the temperature forecast is based on the available data and models, while the actual temperature under the sun reflects the actual weather conditions, which are affected by a variety of factors, such as wind speed, relative humidity, topography, sun exposure, etc. To a certain extent, the actual temperature under the sun is more accurate than the temperature in the weather forecast.

The temperature under the sun and the weather forecast temperature are both temperature values derived from different measurement methods, and their accuracy is related to the measurement method, environmental factors, accuracy, etc. The temperature under the sun is the actual measured temperature, and the measurement error of the thermometer is within the degree, which is more accurate. But it can only reflect the situation for a while, and it may be affected in cloudy days, smog, etc.

The weather forecast temperature is the first value obtained by the meteorological department according to meteorological observation data, numerical models, statistical methods, etc., which can reflect the trend of change in the next few days, but the forecast is also uncertain, and there may be a certain error in Huiming. Therefore, whether it is the temperature under the sun or the temperature forecast of the weather, it needs to be judged in combination with the actual situation and a variety of reference factors when using.

The surface temperature of the Sun: about 5500 degrees Celsius.

The central temperature of the Sun: about 20 million degrees Celsius.

Coronal temperature of the Sun: about 5 106 degrees Celsius The Sun is the closest constant Naida source star to the Chang State Earth and is the central object of the solar system. The mass of the solar system is concentrated on the sun.

The Earth in the solar system, as well as other terrestrial planets and giant planets, orbit the Sun. Also orbiting the Sun are asteroids, meteors, comets, super-Neptune-type objects, and dust.

The composition of the sun.

From the center outward, the Sun can be divided into nuclear reaction zones, radiation zones, tropospheres, and atmospheres. Due to the extremely poor transparency of the outer gases of the sun, what humans can directly observe is the solar atmosphere, which is divided into three layers from the inside to the outside: the photosphere, the chromosphere and the corona.

1. The temperature of the coronal layer can reach 1 million degrees Celsius.

The solar corona refers to the outermost layer of the Sun's atmosphere (its interior is the chromosphere and the photosphere), which is more than a few million kilometers thick. Beyond the chromosphere is the coronal layer, which is extremely hot, with a temperature of 1 million degrees Celsius.

2. The temperature of the chromosphere is 4,600k tens of thousands of degrees from the inside to the outside.

However, the chromosphere has an abnormal distribution of temperature in the solar atmosphere. Within the chromosphere, which is about 2,000 kilometers thick, the temperature increases from 4,600 K at the top of the photosphere to tens of thousands of degrees at the top of the chromosphere, while some other physical parameters (such as density, ionization, etc.) and some physical processes also change dramatically. Therefore, the study of the physical condition of the chromosphere has attracted a lot of attention from solar physicists.

3. The temperature of the photosphere is 5500 degrees.

Although the photosphere is bright as a whole, the brightness of each part is very uneven. The undisturbed photosphere is covered with rice grains, with an estimated total of 4 million pieces, and in the active area of the photosphere, there are sunspots, light spots, and occasionally white light flares.

Their brightness, physical state and structure vary greatly, and the average undisturbed photosphere emits a radiation flux of Erg per square centimeter per second, from which the effective temperature of the photosphere is calculated to be 5500 degrees.
