1. What is road icing?

The warning signal of road icing is divided into three levels, which are represented by yellow, orange and red respectively.

Yellow warning of road icing: When the road surface temperature is lower than 0℃ and precipitation occurs, road icing may occur within 12 hours, which may affect traffic. Orange warning of road icing: When the road surface temperature is lower than 0℃, precipitation will occur, and road icing may have a great impact on traffic within 6 hours. Red warning of road icing: when the road surface temperature is lower than 0℃, precipitation will occur, and road icing that has a great impact on traffic may occur or has occurred within 2 hours.

2. How should students deal with icy roads?

Road icing students should pay attention to:

(1) Pedestrians should be careful and try not to go out, especially try not to ride a bike.

(2) Drivers should take anti-skid measures (such as installing anti-skid chains), pay attention to road conditions, drive slowly and safely, and must obey the command and guidance of the traffic police.

(3) Pedestrians should pay attention to stay away from or avoid motor vehicles and non-motor vehicles.

(4) Educate children not to play in the frozen playground or open space. Tell the elderly not to walk or exercise in icy places. Be careful when you walk outside. Anti-skid riding.

4. What causes modern climate change?

The causes of climate change may be natural internal processes, external coercion, or man-made continuous changes in atmospheric composition and land use.

What are the consequences of global warming?

(1) Climate warming, melting glaciers and rising sea level lead to the loss of ecological groups such as coastal beaches, mangroves and coral reefs, coastal erosion, seawater intrusion into the coastal fresh groundwater layer and salinization of coastal land, which leads to the imbalance of natural ecological environment in coastal areas, estuaries and bays and brings great disasters to the coastal ecological environment.

(2) The water area has increased. Water evaporation is also more, the rainy season is prolonged, and floods are more frequent. The chances of being flooded increase, the degree and severity of being affected by heavy rain increase, and the life of reservoir dams is shortened.

(3) Rising temperatures may melt the ice and snow in the Antarctic Peninsula and the Arctic Ocean. Polar bears and walruses will gradually become extinct.

(4) Many small islands will disappear without a trace;

(5) Due to thermal inertia, the existing greenhouse gases will continue to affect our lives.

(6) The increase of temperature will affect people's fertility, and the sperm activity will decrease with the increase of temperature.

(7) the change of primitive ecosystem.

(8) Used in production fields, such as agriculture, forestry, animal husbandry, fishery and other departments. ...

(9) Infectious diseases and other infectious diseases ... germs will spread the epidemic through extreme weather and climate events (El Ni? o phenomenon, drought, floods, heat waves, etc.), which is harmful to human health. ...

6. How should individuals respond to climate change?

7. Why do some ancient rivers disappear now?

First, there are natural reasons, such as changes in climate and crustal plates, and some reasons may be that those rivers are diverted or blocked because they always produce water or other reasons.

8. What is a "ghost town" and how did it come into being?

Ghost Town is located in a wilderness in Uhur, Xinjiang, China. In the wilderness of this area, ancient castles of different sizes stand. Whenever there is a strong wind, there will be countless sad sounds in this castle, which is as creepy as crying ghosts and howling wolves, hence the name "Ghost Town".

Cause of formation: Uhur area is located in the big wind mouth, and it has been windy for many years, which has caused strong wind erosion on the rocks here. Those plateau-shaped highlands were eroded by strong winds, gradually forming valleys and depressions, while other isolated hills turned into stone piers or columns, so this originally empty Yuan Ye formed castles, mushrooms and columns.

16. Is the snowfall the same as the depth of snow? Please tell the difference.

17. What is dry and cold air flow?

What is the principle of Doppler weather radar?

The theoretical basis of Doppler weather radar is the Doppler effect of electromagnetic waves. The so-called Doppler effect means that when the wave source moves relative to the observer, the frequency of the signal received by the observer is different from the frequency emitted by the wave source, and the difference between the transmitting frequency and the receiving frequency is related to the speed of the wave source movement. The frequency change caused by Doppler effect is called Doppler frequency shift or Doppler frequency. In radar system, this Doppler frequency shift shows the phase change of continuous pulses. Compared with conventional weather radar, the biggest advantage of Doppler weather radar is the Doppler effect, which can obtain the velocity field of atmospheric movement and significantly enhance the detection sensitivity and detection ability.

The weather phenomenon "haze" is a fine particle with a diameter less than 2.5 microns. What are the main reasons and ingredients? List three.

Cause of formation: after the primary pollutants are affected by the relevant environment, secondary organic aerosol fine particles are formed through a series of photochemical reactions.

66. What diseases can be caused by inhaling smog? List three.

Causes diseases such as rhinitis and bronchitis, and long-term exposure to this environment will also induce lung cancer.

67. What is the biggest cause of mountain torrents and mudslides? List two.

natural cause

Weathering of rocks exists in a natural state. In this weathering process, there are not only the decomposition of rocks by oxygen, carbon dioxide and other substances, but also the decomposition of rocks by acidic substances in the air absorbed by precipitation, the decomposition of rocks under the soil by substances secreted by surface vegetation, and the loosening of soil caused by frost freezing and dissolution. These reasons will cause the soil layer to become thicker and looser.

Heavy rainfall is also one of the reasons.

Unreasonable excavation

Unreasonable earth borrowing, slag and quarrying

Deforestation and reclamation

secondary disaster

69. What are the main causes of forest fires in Russia?

The high temperature caused by the anticyclone concentrates the hot air flow from the Mediterranean and Central Asia to the European part of Russia. At the same time, the atmosphere that can absorb ultraviolet rays is layered over the affected areas-the thermosphere suddenly becomes thinner, resulting in excessive ultraviolet rays.
