What is the color classification of lightning warning?

There are four levels of lightning warning color grades, which are represented by four colors: blue, yellow, orange, and red. Lightning activity may occur within 6 hours, and lightning accidents that may cause lightning disasters are classified as yellow. There is a high probability of lightning activity occurring within two hours, or it has been affected by lightning activity and may continue, and the probability of lightning disaster accidents is relatively high in orange level.

There is a very high probability of lightning activity occurring within two hours, or there has been strong lightning activity and it is likely to continue, and the probability of a lightning disaster accident is very high.

When there is thunder and lightning, the shower for showering can also become a "killer". Now home decoration solar water heater.

It is generally installed on the roof, often exceeding the height of the original lightning protection device on the building, so that it is completely exposed to direct lightning strikes. In the event of a lightning strike, these "early-rising" water heaters will bear the brunt of the "beating", not only will the outdoor water heaters be damaged, but the current will also be introduced into the room through the shower and other water pipes and electrical wiring.

The official name of the color icon is the meteorological warning signal, which generally has four color levels of blue, yellow, orange and red, and the severity is increased in turn, indicating that it is general, heavier, more serious, and particularly serious, and the blue is the lowest level of warning, and the red is the highest level of warning.

Note: Not every weather signal has four color levels, some only have two or three.

The color of the warning level is gradually increased according to the level, and it is divided into general (level) - blue, heavy (level) - yellow, severe (level) - orange and very serious (level) - red.

Weather warning color level signal, the original warning is divided into these, do you know what they are?

1. Blue alert.

Lightning activity may occur within 3 hours, and lightning disasters may occur.

2. Yellow warning: lightning activity may occur within 3 hours, accompanied by strong winds above level 6, or short-term heavy precipitation, or Xiaoice hail.

There is a high probability of lightning and high winds.

3. Orange alert.

Strong thunder and lightning activity may occur within 3 hours, accompanied by strong winds of 8 or higher, or short-term heavy precipitation, or hail, and there is a high possibility of thunder and wind disasters.

4. Red warning: Strong thunder and lightning activities may occur within 3 hours, accompanied by strong winds above level 10, or short-term heavy precipitation, or hail, and the possibility of thunder and wind disasters is very high.

Thunder: Lightning is the phenomenon of electrical discharge in thunderstorm clouds. The formation of thunderstorm clouds generally requires two conditions, sufficient water vapor and violent convective movements. In winter, due to the cold and dry air, coupled with solar radiation.

It is weak, and it is not easy to form convection currents in the air, so there are few thunderbolts. However, sometimes thunderclouds are formed in winter when the temperature is high, and thunder and lightning are generated, and rain and snow occur. Convection is particularly strong and can also form hailstones, which can produce the so-called winter thunderstorms.

Knowing these reasons, it is not surprising that there is a winter thunderstorm.

Thunderstorm and Gale Blue Warning Signal Meaning:It may be affected by thunderstorms and strong winds within 6 hours, with an average wind strength of more than 6, or gusts of 7 or more accompanied by thunder and lightning; or have been affected by thunderstorms and gales, with an average wind force of 6 or 7, or gusts of 7 or 8 accompanied by thunder and lightning, and may continue.

Meaning of Red Warning Signal for Thunderstorms and High Winds:It may be affected by thunderstorms and strong winds within 2 hours, with an average wind force of more than 12 accompanied by strong thunder and lightning; or have been affected by thunderstorms and strong winds, with an average wind force of 12 or more accompanied by strong thunder and lightning, and may continue.

To sum up: the red warning for thunder and lightning is stronger.

People can get the thunderstorm and gale warning signal issued by the meteorological department through television, radio, household networking, mobile phone text messages, etc., or the electronic display board issued by the early warning signal, and pay attention to taking corresponding preventive measures. According to different colors, it is divided into four grades: blue, yellow, orange, and red.

Gansu issued a thunderstorm and gale warning signal:

On June 14, 2008, Gansu Province issued a thunderstorm and gale warning Longnan, Tianshui and Qingyang need to be protected against thunderstorms. According to accurate meteorological data, strong convective weather such as thunderstorms and strong winds will occur in the southern part of Gansu Province.

The Lanzhou Central Meteorological Observatory issued the first thunderstorm and gale warning signal in Gansu in the summer of 2008, urging the southern regions of Gansu Province such as Longnan, Tianshui and Qingyang to step up their response to reduce the possible losses caused by meteorological disasters to local industrial and agricultural production and the safety of people's lives and property.

Thunder and lightning warning signals are classified as yellow, orange and red. What do they mean?

(1) Yellow lightning warning

Standard: Lightning activity can occur within 6 hours and may result in lightning strikes.

2.Keep an eye on the weather and try to avoid outdoor activities.

2) Orange lightning warning

There are yellow, orange, red. Yellow indicates that lightning activity is likely to occur within six hours, which may cause lightning accidents. Orange indicates that there is a high probability of lightning activity within two hours.

or have been affected by lightning activities, and there is a high possibility that lightning disasters may continue to occur. Red indicates that there is a very high probability of lightning activity within two hours. Strong lightning activity has already occurred, and lightning disasters may continue to occur.

The level of early warning signals is generally divided into four levels according to the degree of harm, urgency and development trend that meteorological disasters may cause: level (general), level (severe), level (severe), level (particularly serious), and are indicated by blue, yellow, orange and red.

Warning signals consist of names, icons, standards, and defense guidelines, and are divided into typhoons, heavy rains, blizzards, cold waves, high winds, sandstorms, high temperatures, droughts, thunder, hail, frost, fog, haze, and icy roads.

The level of early warning signals is generally divided into four levels according to the degree of harm, urgency and development trend that meteorological disasters may cause: level (general), level (severe), level (severe), and level (particularly serious), which are indicated by blue, yellow, orange and red, and are marked in Chinese and English. Meteorological Disaster Warning Signals and Defense Guidelines.

Lightning warning precautions.

Do not stay on the platform of high-rise buildings during thunderstorms, and do not enter isolated sheds, sentry boxes, etc. in outdoor open spaces.

Keep away from exposed metal objects such as water pipes and gas pipes and electrical equipment outside buildings.

It is not advisable to take shelter from thunderstorms under large trees, and if you have to do so, you must keep a distance of 3 meters from the trunk of the tree, squat down and keep your legs together.

The early warning level of natural disasters, accident disasters and public health events that can be warned shall be based on the urgency of the occurrence of the emergency, the development trend and the possible cause.

The yellow alert is mild, the orange alert is moderate, and the red alert is severe.
