What does the weather cloud red mean?

Question 1: Who knows what the blue-gray-red index on the left side of the satellite image stands for? The redder the number, the more negative it is; the lower the number, the bluer the more positive it is. What do you mean? This is an infrared cloud picture. You can see the reflectivity and height of the cloud top.

Red is a cloud with a very high cloud top, which is generally a strong convective cloud, that is, a cloud with a lot of thunder and a little rain.

Blue is invisible on the map, and generally it is sunny as long as it reaches the value of 0.

So the value on the left is the convective value of clouds, which has nothing to do with land and sea.

Question 2: H on the meteorological cloud picture; What do I represent? H: What do you mean by height?

L: meaning of l: length

It is very similar to the x and y axes in plane coordinates, but h and l represent the direction in space.

Question 3: How to identify the color warning on the weather map? What are the early warnings on the cloud map every day? It really makes people see that the first five points of the weather forecast are blue, yellow, orange and red in turn, which are marked in Chinese and English, representing average, heavy, serious and super serious respectively. This practice was followed by Europe and America in China, starting in the last two years. Generally speaking, it is above the orange signal.

The following is an introduction of the warning signal by Anhui Meteorological Bureau, which may be helpful for the landlord to understand this thing.

In order to prevent and mitigate meteorological disasters, protect people's lives and the safety of the state, collectives and individuals' property, according to the Meteorological Law of People's Republic of China (PRC) and the Regulations on Meteorological Management of Anhui Province, combined with the actual situation of our province, the Anhui Meteorological Bureau and the Anhui Provincial Bureau of Radio, Film and Television jointly studied and formulated the Provisions on the Release of Meteorological Disaster Early Warning Signals in Anhui Province, which are hereby promulgated. All units shall cooperate with each other as required.

First, the early warning signal of meteorological disasters in Anhui Province is the unified signal of our province's defense against meteorological disasters, and the early warning signals of meteorological disasters in various places must abide by these provisions.

2. The warning signals of meteorological disasters in Anhui Province shall be uniformly issued by the meteorological offices and stations subordinate to the competent meteorological departments at or above the county level, and no organization or individual may release them to the public in any way. The release standards, grades and categories of meteorological disaster warning signals shall be implemented in accordance with the Guidelines for the Release and Defense of Meteorological Disaster Warning Signals in Anhui Province (annex 1).

3. The early warning signals issued by our province are tentatively classified into seven categories, such as typhoon, rainstorm, high temperature, cold wave, low temperature and cold, thunderstorm and gale, which are generally divided into four levels (IV, III, II and I). According to the severity and urgency of the disaster, the colors are basket, yellow, orange and red in turn, and they are marked in Chinese and English, representing ordinary, heavy, serious and super-serious respectively. The whole province.

Question 4: What do the different colors on the satellite images mean? The green color in the satellite cloud image represents the land. When you see the green color, it means the weather is fine.

Blue represents the ocean. When you see blue, it means it's sunny.

White is a rainy area. The whiter the color, the thicker the clouds. The brighter the white, the more obvious the precipitation, and the darker the white, which is generally cloudy.

Question 5: What are the yellow, red and blue weather forecasts and disaster warnings? Early warning signals are divided into eleven categories, such as typhoon, rainstorm, high temperature, cold wave, fog, thunderstorm and gale, gale, sandstorm, hail, blizzard and road icing. Early warning signals are generally divided into four levels (IV, III, II and I). According to the severity and urgency of the disaster, the colors are blue, yellow, orange and red in turn, and they are marked in Chinese and English, representing ordinary, heavy, serious and particularly serious respectively. According to the characteristics and early warning ability of different disasters, the early warning grades and standards of different disasters are determined. When a variety of meteorological disasters occur or are expected to occur at the same time, a variety of early warning signals can be issued simultaneously according to the corresponding standards.
