Does it have to rain on severe convective weather?

Convective rain. It is a precipitation phenomenon caused by convective movements in the atmosphere, and is also customarily called a hot thunderstorm.

Convective rain is most abundant at low latitudes, and precipitation is generally in the afternoon, especially in the equatorial region.

The precipitation time is very accurate.

Convective rain is humid and hot when the air is strongly heated.

Convective rain is called convective rain when the air expands and rises, and the water vapor in the air cools and condenses. Convective rain is dominant in the equatorial region throughout the year, and convective rain in our country is mostly seen in the summer afternoon.

The so-called severe convective weather actually refers to the occurrence of short-term heavy precipitation or short-term thunderstorms and strong winds, and strong convective weather also includes tornadoes and hail, which is actually a kind of disastrous weather. In various parts of the country, in fact, the time of strong convective weather is different, under normal circumstances, the southern man appears earlier, and in Guangdong, this kind of strong convective weather will occur throughout the year. <>

If it is a short period of heavy precipitation, it can usually be seen all year round, but it is usually more common in spring, summer, and autumn. If it is a thunderstorm and windy weather, it generally occurs in spring, summer and autumn, and winter is relatively rare. If it is a tornado, it usually occurs in the transition season between spring and summer, and it also occurs during the summer and autumn communication, that is, from April to October every year, in fact, it is the peak period of tornadoes.

In the case of a squall line, it usually occurs during the transition between spring and summer, and if there is a typhoon, then there is also a squall line, which mostly occurs from March to September every year. If there is hail, it is mostly when the cold and warm air are more intense, and it is more common from February to May. However, it is also possible to land ice during the remaining intense and persistent thunderstorms, but this is generally rare.

Severe convective weather generally occurs in local areas, but the destructive power is often very strong, and this kind of strong convective weather comes and goes quickly. However, severe convective weather can usually be predicted, and although it is difficult to accurately forecast a small area, it can be detected from the radar several hours in advance. It can be judged by the signs on the radar echo map, if it is light green, it means that there will be rain, and if it is dark green, it means that there will be heavy rainfall.

If there is a red or even purple replay, it means that there will be strong convective weather such as thunderstorms, strong winds, and hail. <>

Severe convective weather refers to convective winds, hail, and short-term heavy precipitation accompanied by thunderstorms. Severe convective weather occurs in small and medium-scale weather systems with small spatial scales. Generally, the horizontal range is about 10 kilometers to two or three hundred kilometers, and some have a horizontal range of only a few tens of meters to more than 10 kilometers.

Most of these weather events bring heavy rain, which can lead to torrential rains and can cause big problems for local life.

My understanding is that this kind of weather will last for a week or so, and then the weather will change to sunny days.

Severe convective weather refers to convective gales (hail, short-term heavy precipitation) accompanied by thunderstorms.

Severe convective weather occurs in small and medium-scale weather systems, and the spatial scale is small, with a general horizontal range of about 10 kilometers to 2300 kilometers, and some horizontal ranges are only a few tens of meters to more than 10 kilometers. Its life history is brief and distinctly sudden, ranging from one hour to more than a dozen hours, with a shorter period of only a few minutes to an hour.

Severe convection is a weather phenomenon caused by the strong vertical movement of air. The most typical is the strong convective weather in the summer afternoon: during the day, the ground absorbs the short-wave radiation emitted by the sun, the temperature rises, and the long-wave radiation is released to heat the atmosphere.

When the air near the surface receives enough heat from the Earth's surface, it expands and decreases in density, leaving the atmosphere in an unstable state.

It's like oil and water in a tank, when the less dense oil is at the bottom of the tank and the water is at the top, there is bound to be a strong upward movement and eventually the oil will float to the surface.

In the same way, the hotter air near the surface rises under buoyancy and forms a rising stream of hot and moist air. When rising to a certain height, the water vapor contained in the air condenses into water droplets due to the drop in temperature. As the droplets fall, they are carried up by the stronger updrafts, and so on, until the small droplets begin to accumulate into large droplets until the upper-air currents are unable to support their weight and finally fall into rain.

This is also the reason why summer thunderstorms are not as drizzly and large as spring rains.

Severe convective weather refers to the disastrous weather that occurs in short-term heavy precipitation, thunderstorms and gales, tornadoes, hail and squall lines, which occurs in convective cloud systems or single convective cloud blocks, and belongs to small and medium-scale weather systems in meteorology. The horizontal scale of this weather generally ranges from a few kilometers to 200 kilometers.

Heavy rainfall + strong convection, 12 provinces will experience heavy to heavy rain, and bad weather will last for one to two weeks. One thing is for sure, and that is that if there is not enough protection, it can easily cause flooding. What should we do in this situation?

The first is to do a good job of flood prevention, and the second is to take precautions to prevent being caught in the rain or drowning, and to remind those who want to travel during this time to be sure to plan their travel and not to go to these provinces with heavy rainstorms.

Heavy rainfall + strong convective weather does not pass quickly, it will always last for a while. This period can be a week or two weeks. If it lasts too long, people need to be prepared, such as stocking up on some groceries or racking up their own cars first, as they did last year.

Spring and autumn are always the same kind of continuous rainy weather, so be sure to be prepared.

Severe weather is a concern because it usually lasts for a long time. If it is only a short period of heavy rainfall, it will not cause much trouble to people, but if it is a continuous bad weather, then people's clothing, food, housing and transportation will be affected, so the most important thing is that we must be ready to evacuate at any time, but in the current situation, I think it should not be necessary, because if this sudden heavy rainfall will really cause large-scale flooding, there will be a good emergency measure.

The duration of severe weather is a bit of experience, and it is likely to be accurate, but it is not completely accurate. The other day I looked at the weather forecast and reported a day of rain, but in the end I still didn't see a drop of rain. Therefore, you must prepare what you should prepare, but it does not affect your normal life.

Such bad weather generally does not last long, and it will end in about 1 or 2 days. We should take precautions and reduce going out.

It may last for about a week, this time the rain range is very large, the strength of the receptors is very much, such as Henan, Anhui, Jiangsu, Shanghai, Hubei, etc. are very windy, and very heavy rain.

There is no way to judge, different places, the duration of the time is definitely different, be sure to prepare in advance.

Convective rain is a precipitation phenomenon caused by convective movement in the atmosphere, which is also customarily called convective rain. Convective rain will be formed when the air near the ground level is heated or the air above the upper layer is strongly cooled, which causes the air in the lower layer to rise, and the water vapor cools and condenses. Convective rain is often preceded by high winds, which can uproot trees up to 50 cm in diameter, accompanied by lightning and thunder, and sometimes hail.

Convective rain is mainly produced in cumulonimbus clouds, ice crystals and water droplets coexist in cumulonimbus clouds, the vertical thickness and water vapor content of clouds are particularly large, and the air flow rises and falls very strongly, up to 20 30 m seconds, and there is an electric charge in the clouds, so cumulonimbus clouds often develop into strong convective weather, producing heavy rainstorms. Lightning strikes, strong winds, and heavy rainstorms often occur during such thunderstorms.

Cumulus light clouds are thin and contain little water, and rain generally falls to the ground. Cumulus congestus rarely receives precipitation in the middle and high latitudes, but in the lower latitudes, precipitation can sometimes be produced because of the abundance of water and strong convection.

Convective rain is most abundant at low latitudes, and precipitation times are generally in the afternoon, especially in equatorial regions, where precipitation times are very accurate. In the morning the sky is clear, as the sun rises, the sky cumulus clouds gradually form and develop quickly, thicker and thicker, in the afternoon, the cumulonimbus clouds are surging, the weather is hot and sultry, the wind blows, thunder and lightning, the torrential rain pours down, the precipitation continues until dusk stops, after the rain the sky is clear, the weather feels a little cooler, but the next day, there are repeated thundershowers. In the middle and high latitudes, convective rain mainly occurs in the summer half of the year, and is extremely rare in the winter half of the year.

Do you know what convective rain is?

When a frontal rain is active, the precipitation caused by the rising and cooling condensation in the warm and humid air is called frontal rain. Fronts are often accompanied by cyclones, so frontal rain is also called cyclonic rain. There is a systematic cloud system on the front, but not every type of cloud can produce precipitation.

It refers to the meeting of the cold air mass and the warm air mass, and the warm air mass is lifted to form rainfall, such as the plum rain in the south and the cold wave in the north. Convective rain refers to the heat of a place and the heat of the air to rise, forming rainfall, such as heavy rains in summer.

Frontal rain features.

1. When the front is active, the precipitation phenomenon caused by the rising cooling and condensation in the warm and humid cavity collapse air is called frontal rain.

2. Fronts are often accompanied by cyclones, so frontal rain is also called cyclonic rain. There are systematic cloud systems on fronts, but not every type of cloud produces precipitation. When two air currents with different properties meet, the interface between them is called a front.

3. On the front, warm, wet, and lighter air is lifted over cold, dry, and heavier air. In the process of uplifting, the water vapor in the air cools and condenses, and the precipitation formed is called frontal rain.
