Why doesn t it rain in the countryside, how won t it rain this year

Cities have gray underlying surfaces, i.e., asphalt roads and concrete houses, which heat up quickly and evaporate surface water faster, increasing water vapor in the air. In addition, asphalt roads slow down the infiltration of surface water and reduce water loss, which also increases the amount of surface water evaporation. Therefore, the city is more prone to rain, which is called the urban rain island or heat island effect (the urban temperature is higher than that of the suburbs and the countryside, due to the influence of air pressure, the air flows from the suburbs to the city, rises in the city, and condenses into rain after cold, so the urban rainfall is greater than that of the surrounding countryside, and the countryside is in the periphery of the urban-rural circulation, so the air sinks here and there, and the precipitation is less.

In addition, the infiltration of soil ground and vegetation is intensified, so that the surface water is reduced, and the water vapor in the air is insufficient).

In the absence of cold air from outside, rain depends on the neutralizing effect of cloud-ground charges. Under the action of ultraviolet, the cloud aerosol is generally positively charged, and the cloud water molecules and dust particles have a great force to dismantle each other, and the distance between them is greatly reduced after the negative electricity on the ground is neutralized. Compared with rural areas, due to the higher buildings and stronger tip discharge capacity at the same negative power level, not to mention that the city is generally distributed by rivers, the conductive effect is better, the relative negative power level is high, the voltage difference between the cloud and the ground is larger, the neutralization effect is better, and it is relatively easier to rain.

The chances of rain in rural areas are no less than in cities, and the amount of rain has little to do with location. The reasons why it rains more in urban areas than in rural areas may be as follows:

1.The urban "heat island effect": urban temperatures are higher than those in the suburbs and rural areas, which causes air to flow from the suburbs and rural areas to the cities, where it rises and then condenses into rain when it is cold.

2.Effects of land use type: For example, rural land is typically more empty and has less vegetation, while urban land typically contains more concrete and asphalt pavement, which absorb and release heat more easily, affecting rainfall patterns.

It is important to note that the climate and rainfall patterns of each region have their own unique characteristics and need to be understood according to the specific geographical environment and climate characteristics.

It's not that it doesn't rain in the countryside. There is no rain in the city to choose this saying. The rain factor is that there must be cumulonimbus clouds, and the rain will only occur under the conditions of rain, such as clouds and cold air condense into small water droplets, and the small water droplets gather into raindrops.

Summary. Hello, in 2022, there will be more high temperature days in northern China, this is because the climate is dry, there is no rain for a long time, and there are no cooling conditions, resulting in the temperature has been maintained in a high temperature state. The rain in the south is mostly because of the introduction from June:

In hot days, everyone must pay attention to avoid the heat, many people will accidentally suffer from heat stroke, which can easily cause damage to the body.

How not to rain this year.

Hello, in 2022, there will be more high temperature days in northern China, this is because the climate is dry, there is no rain for a long time, and there are no cooling conditions, resulting in the temperature has been maintained in a high temperature state. The rain in the south is mostly because of the introduction from June: In the hot days, everyone must pay attention to the heat, many people will suffer from heat stroke if they are not careful, and this kind of weather is easy to cause damage to the body.

2022 is hotter than usual, and since June this year, over the subtropical region of the Northern Hemisphere, the western Pacific subtropical high belt, the Atlantic high pressure belt and the Iranian high pressure have all strengthened in stages, thus forming a wide range of global warm high pressure belts. Under the control of the warm high-pressure belt, the prevailing downdraft is conducive to the warming of the ground, and under the action of the large-scale high-pressure belt, the air is relatively dry and not easy to form clouds, which also makes it easier for solar radiation to reach the ground, resulting in frequent and strong high temperatures, which in turn causes continuous high temperature and heat wave events in many places in the northern hemisphere. Since the beginning of the 21st century, the typical years of large-scale continuous high temperature events in China include 2003, 2013, and 2017.

Overall, this year's high temperature event started earlier than the above three years, the duration and the number of historical extreme stations are currently less than these three years, and the impact range and maximum temperature of a single station are not as good as in 2017, but have exceeded those in 2003 and 2013.

This means that this year's harvest may not be too good.

As the saying goes, "If it doesn't rain, you will starve to death this year". In ancient times, farmers all looked at the sky for food, and the annual harvest was all based on the quality of the weather. If it doesn't rain on this day, it means that this year's harvest may not be very good.

Because the season of thunder and rain should be closed, but there is no rain, unconventional, this year is not expected to be very smooth, although the second half of the sentence, this year to starve to death, is a bit of an exaggeration, but the saying still has some wisdom of the working people in it.

Stunned is the third of the 24 solar terms. Fighting nails, the sun reaches the yellow longitude of 345°, and the festival meets on March 5-6 of the Gregorian calendar. The sting reflects the state of germination and growth of organisms in nature affected by changes in rhythms.

When it is shocking, the yang energy rises, the temperature warms up, the spring thunder moves, the rain increases, and everything is full of vitality. Farming production is closely related to the rhythm of nature, and the stinging solar term has a very important significance in farming, which is the reflection of the ancient farming culture on the natural season.

"Sting", refers to "hiding in the soil", insects are hidden in the soil in winter; "Startled" means "awakened", and the spring thunder in the sky woke up the stinging insects. The so-called "spring thunder startled insects" refers to the stinging season, the spring thunder begins to roar, waking up the stinging insects that are dormant in the ground for wintering. In ancient times, on the day of stinging, people in some places used incense and wormwood to smoke the four corners of the house, and used the fragrance to drive away "snakes, insects, mosquitoes and rats" and musty smells.

In addition, there are customs such as "covering drum skin", "eating pears", and "sacrificing white tigers to resolve right and wrong".

The iconic early land expedition of the stinging solar term is the spring thunder and all things are full of vitality. From the perspective of the natural phenology process of sedan chairs in various parts of China, due to the large span from north to south, the time of the beginning of spring thunder is different sooner or later. "The first thunder of the sting" only coincides with the natural rhythm of parts of southern China.

We sometimes wonder how the ancients in the past did not have advanced scientific and technological equipment to optimize the weather, so how did they carry out agricultural activities in the ever-changing climatic conditions? The answer is the 24 solar terms. The weather of nature is ever-changing, but all changes are not separated from their origins, after a long time of observation and judgment, its laws can also be well understood, the 24 solar terms are the ancients of the meteorological changes of the aggregate.

However, we are still on the road of exploration, and the older generation has mastered a lot of rules through long-term experience, forming a popular saying. "Dog days without rain in the beginning of summer" is one of them, so what does this sentence mean?

What does the meaning of the three dog days of the beginning of summer be rainless, and the complete saying is "no rain in the beginning of summer, three dog days are hot, Chongyang is rainless and sunny in winter". Meaning, if it doesn't rain on the day of the beginning of summer, then this year's dog days will definitely be particularly hot and difficult. During the Chung Yeung Festival, if there is no rain, then there will be very little rain throughout the winter, which is what people call a warm winter.

Although this statement is not 100% accurate, it is a probabilistic event summarized by the older generation in their lives and work, and it should also be a natural phenomenon that occurs frequently.

In fact, if this proverb is to be explained, there is also a certain scientific basis for stupidity. Why is it that there is no rain on the day of the beginning of summer, and there will be dog days and heat? In fact, the arrival of the summer is equivalent to entering the summer, if there is no rain on the day of the beginning of summer, it is obviously rich in tropical high pressure, always controlling the atmospheric pressure, resulting in the cold air in the south and the north can not come, and the warm and humid airflow in the south can not come, so that the humidity and temperature of the air can not be lowered for a period of time, causing the main reason for the hot weather.

Therefore, if it does not rain in the beginning of summer, it will be difficult to sow crops in the later period, and then it will become a vicious circle, the hotter it is for the growth of crops, the more unfavorable it is for the growth of crops, if the crops are not good, the land lacks green vegetation cover, and it will be hotter, so it will not rain in the beginning of summer, and there will be less rain this summer, and there will be less green vegetation covering the land, so the dog days must be very hot. Therefore, whether it rains around the beginning of summer will not only affect the weather in the future, but also affect the harvest of the year.

The weather in 2022 is so abnormal because the environment has been polluted, and the atmospheric environment is extremely unoptimistic. And this year's extreme weather is very much, whether Sakura Chong is too hot or too cold is not normal. This kind of weird atmosphere makes many people unbearable, so it is really a very important thing to say that the protection of the Ring Ascension Song Realm starts with us.

If we treat this matter as an unimportant thing, then sooner or later people will pay a heavy price for their actions.

The lack of rain is due to the state of the atmosphere and natural climate change.

1. Atmospheric sock layer: There is a complex hierarchy of temperature and humidity in the atmosphere. Changes in these levels affect the ability of the air to rise and condense, which in turn has an impact on rainfall.

How would you rate this? Collapse.

Summary. Spring Rainy Times Spring generally starts at the end of March and ends at the end of May. This season is a critical period for crop growth, and if there is not enough rainfall, it will have a great impact on the growth of crops.

Normally, spring rainfall is concentrated in the afternoon and evening, and it is necessary to pay attention to the weather forecast during this time period to prepare for possible rainfall. Summer Rainy Time Summer is generally from June to September, and this season is the hottest time and there is more rainfall. In summer, it rains more regularly, usually in the afternoon or evening.

Due to the heavy rainfall in summer, farmers need to take timely drainage measures to avoid flooding affecting planting and harvesting.

Rain, nuclear fallout, is the process by which moisture in the atmosphere condenses and falls to the ground after forming clouds. The main reason for rain is that water vapor cools in the atmosphere and forms water droplets, which then come together to form clouds and precipitation.

A few of the main reasons for rain include:

1.Evaporation and evaporative cooling: When the sun hits the surface, the water in the water body evaporates into water vapor. As these water vapors rise into the atmosphere, they gradually cool down, forming clouds.

2.Convection: When the ground is heated, the air will be heated and rise wide, forming convection. When the rising air reaches saturation, the water vapor in it begins to condense into water droplets, forming clouds.

3.Water vapor condensation nucleus: The presence of tiny particles in the atmosphere, such as dust, smoke, salt particles, etc., can act as the core of water vapor condensation, prompting water vapor to condense into clouds and precipitation.

4.Updrafts: Altitude changes in the topography or the meeting of different air masses can cause the airflow to rise, allowing water vapor to cool and form clouds and precipitation.

Rain is essential for the continued functioning of the Earth's ecosystems and life. It provides water for plants, maintains water levels in rivers and lakes, helps crops grow, and maintains the earth's water cycle. In addition, rain can also purify the air and wash away dust and pollutants.

The rain in the sky is due to the action of the water cycle. The water cycle refers to the process by which water on the Earth's hand scales is continuously transformed and flowed between different forms. The processes of the water cycle include evaporation, condensation, precipitation, and surface runoff.

When the sun hits the earth's surface, the surface moisture will be heated and evaporate into water vapor, which will rise into the atmosphere, and as the altitude increases, the water vapor will meet the cold air, and the water vapor will condense into clouds. When the water droplets in the clouds are large enough, they fall to form precipitation, including rain, snow, hail, etc.

In fact, there are many reasons why it rains in the sky, including temperature, humidity, air pressure, and other factors. When the temperature rises, the rate of evaporation of surface water accelerates, and the water vapor rises into the atmosphere, forming clouds. When the water droplets in the clouds are large enough, they fall to form precipitation.

Humidity is also one of the factors that affect rain in the sky, and when the air is saturated with moisture, clouds and precipitation are formed. The air pressure also affects the sky when it rains, and when the air pressure is low, the air rises, forming clouds and precipitation.
