Meteorology * * * Meteorology * *, a Chinese word, refers to all atmospheric physical phenomena such as wind, clouds, rain, snow, frost, dew, rainbow, halo, lightning, thunder and lightning in the sky. The following is about:

First, the living environment temperature.

Anthropologists believe that "human beings originated near the isotherm of 2 1℃ on the earth" because this climate environment is most suitable for human production and life. According to research, for most people, the ambient temperature is 17? At 22℃, the human body feels most comfortable; The temperature is 15? 18℃ is most suitable for light manual labor; The temperature is 7? 17℃ is most suitable for heavy manual labor; The temperature is 10? 18℃ is most suitable for mental work; Room temperature 20? 25℃ is good for rest; The room temperature for a nap should not be lower than 28℃; The most comfortable panel temperature for dressing is around 33℃; The optimum temperature of human body is 37℃; Summer swimming water temperature 25? 30℃ is appropriate; Optimum temperature for morning exercise 15? 20℃; The suitable temperature for eating is 45? 60℃; The temperature of drinking water is 50? 60℃; The temperature of the sunshine bath is 15? 30℃; The sand temperature should be 4 10 cm during sand treatment. 45℃。

Second, the disease-prone climate.

What is the suitable climate for hepatitis? 20℃; What is the most suitable climate for malaria 16? Above 20℃; 15 temperature is the most prone to intestinal and gastric infectious diseases? The incidence rate is high in the climate of 65438 09℃; What is the best climatic environment for meningitis? 10℃, and the most unfavorable climatic environment is above 22℃; When the temperature is greater than 35℃, the heartbeat is accelerated, breathing is difficult, and overheating phenomena such as edema, syncope and sweat gland disorder are prone to occur; When the temperature exceeds 37℃, muscle spasm, heatstroke or severe heatstroke, dehydration and even death are most likely to occur; The climatic environment with high incidence of cardiovascular and cerebrovascular diseases is sudden cooling below -5℃ and extreme heat above 35℃.

Third, the storage temperature of goods.

The storage temperature of tea should be lower than 65438 00℃; The storage temperature of fresh meat is about 5℃; What is the best thawing temperature of frozen meat 10? 15℃; The storage temperature of fresh eggs is-1? 1℃; The storage temperature of tomatoes is 13? 20℃; The optimum storage temperature of banana is 12? 13℃; The storage temperature of pineapple is 8? 9℃; The storage temperature of citrus is 1? 8℃; The storage temperature of cucumber is 1? 10℃; The storage temperature of apples is 0? - 1℃; The storage temperature of pears, peaches, apricots, grapes, melons and carrots is 0? 1℃; The storage temperature of Chinese cabbage is -2? 2℃……

aerography

The objects of meteorological research are the laws of atmospheric motion in all layers of the atmosphere, the weather phenomena in the troposphere and the distribution of drought, flood and cold and warm on the ground. Such as clouds, fog, rain, snow, hail, lightning, typhoon, cold wave and so on. Are common weather phenomena. Its research scope is the atmosphere on the surface of the earth, which is about 3000 kilometers thick. According to the thermodynamic structure, it can be divided into troposphere, stratosphere, mesosphere, warm layer and escape layer from bottom to top. According to electromagnetic characteristics, it can be divided into neutral layer, ionosphere and magnetosphere; It can be divided into homogeneous layer, turbulent layer and heterogeneous layer according to chemical composition.

There is a cloud in the sky. When sunlight or moonlight refracts and reflects through ice crystals in clouds, it will produce a colorful halo around the sun or moon. The order of halo colors is internal infrared purple. These seven color rings are called solar halo or lunar halo, which are collectively called solar halo. Among them, the halo with an angular radius of 22 degrees is the most common for observers, which is called 22-degree halo. Occasionally, you can see a halo with an angular radius of 46 degrees and other forms of halo-like light arcs. Halo occurs because of cirrostratus, and cirrostratus is often hundreds of kilometers away from the rain front area. With the advance of the front, the rain area may move in the near future, so halo often becomes a harbinger of rainy weather.

Magnificent

There is a transparent thin cloud in the sky, and the water droplets in the cloud are uniform in size. If the cloud is composed of ice crystals, the ice crystals should be uniform in size. When moonlight or sunlight passes through clouds, it is diffracted by even cloud droplets or ice crystals, and as a result, it will cling to the disk of the moon or the sun around it, forming an inner ultraviolet red ring called Hua. Because the sun is too bright, it is not easy for people to observe the sunrise, and moonlight is more common. The flowers near the moon disk are also called canopy. Usually the purple of the canopy is not obvious, so the inner ring is blue-green, the outer ring is mainly yellow, and the outer ring is red. Sometimes after a dark circle outside the crown, one or even several concentric rings with the same color order as the crown appear, but the brightness is much weaker, which is called Yahua.

Hongheni

The sunlight which is emitted into the atmosphere and contains seven colors of light, water drops, raindrops or fog drops can form a colorful light arc ring on the rain curtain or fog curtain after refraction and reflection. When the angle radius of the light arc ring to the observer is about 42 degrees and the halo color sequence is internal ultraviolet red, it is called rainbow.

On the outside of the rainbow, sometimes a weak color halo appears, and the angular radius of the halo to the observer is about 52 degrees. The order of color rings is opposite to that of rainbow, that is, internal infrared purple, which is called neon or auxiliary rainbow.

Rainbow and neon can only be observed if they stand with their backs to the sun. In summer evening, when the sky in the west is sunny and the sky in the east is rainy, it is easiest to see rainbows and neon lights.

dusk

Before sunrise, that is, before the sun is above the horizon, the sun shines into the upper atmosphere and is scattered by atmospheric molecules, resulting in a slightly brighter sky and a slightly brighter ground. The light from this moment until the sun comes out of the horizon is called dawn.

After sunset, that is, after the sun falls below the horizon, there is still a time when the sun can shine on the upper atmosphere, and the sky and the ground remain dark because of the scattering of air molecules. This light is called dusk.

The photosynthesis of dawn and dusk is called twilight. Dawn is called dawn, and dusk is called dusk. Due to the different standards for the beginning and end of dawn, it is usually divided into civil twilight, sea dawn and astronomical dawn. On sunny days, when the angle of the sun below the horizon is about 7 degrees, civil dawn begins and dusk ends; At about 12 degrees, the voyage begins at dawn and ends at dusk; At about 18 degrees, astronomical dawn begins and dusk ends. The duration of dusk is the shortest at the equator and increases with the increase of latitude.
