What is the difference between dry and drought? The difference between the meaning of drought and dr

There are two pronunciations of "gān" and "gàn", and there are many meanings, among which there is a word meaning when reading "gān" is "no water or less water", which generally refers to the small water content of a certain item, such as dry, drought, dry, dry firewood, dried tofu and so on.

Drought has only one pronunciation of "hàn", and there are two basic meanings, one of which is "no rain for a long time, lack of rain, lack of water, as opposed to "waterlogging". Generally, it is mostly related to weather and climate, such as dry season, drought, drought, drought prevention, drought, etc."

The term dry and drought refers to "a climatic phenomenon in which the total amount of fresh water is low due to the lack of rainfall for a long time, the air is dry, and the soil is short of water, which is insufficient for human survival and economic development".

Dry and dry are a separate word. For example: cleaning, eating and drinking, sleeping, getting up, riding in the car, running, talking. Alas! You are this question like a foreigner.

Drought refers to a climatic phenomenon in which the total amount of fresh water is low enough to meet the needs of human survival and economic development, and is generally a long-term phenomenon. Drying refers to the process of vaporizing the moisture (or solvent) in the material with heat energy in the chemical industry, and the vapor generated by the inert gas is carried away.

Type of drought

1. Meteorological drought: According to the insufficient precipitation, it is expressed as the absolute value of precipitation over a specific duration.

2. Arid climate: According to the insufficient precipitation, it is not expressed in a specific amount, but in a ratio to the average or normal value.

3. Atmospheric drought: It involves not only precipitation, but also climatic factors such as temperature, humidity, wind speed, and air pressure.

4. Agricultural drought: It mainly involves soil moisture content and plant ecology, perhaps the characteristics of a specific crop.

5. Hydrological drought: the reduction of river flow, the reduction of lake or reservoir capacity and the decline of groundwater level are mainly considered.

6. Water management drought: It is characterized by water shortage caused by the actual operation of water management or the destruction of facilities.

Drying type

1. Convection drying: make the hot air or flue gas in direct contact with the wet material, rely on the convection heat transfer to supply the material, and the water vapor is carried away by the air flow. Convection drying is the most widely used in production, including air flow drying, spray drying, fluid drying, rotary cylinder drying and chamber drying.

2. Conduction drying: the wet material is in direct contact with the heated wall, the heat is transmitted from the wall to the wet material by heat conduction, and the water vapor is discharged by the extraction device. It includes drum drying, freeze drying, vacuum rake drying, etc.

3. Radiation drying: heat is projected onto the surface of wet materials by radiation heat transfer, which is absorbed and converted into heat energy, and water vapor is discharged by the extraction device, such as infrared drying.

4. Dielectric heating and drying: the wet material is placed in a high-frequency electric field, and the moisture is vaporized by electric energy heating, including high-frequency drying and microwave drying. In the three types of drying methods, conduction, radiation, and dielectric heating, the heating of the material is independent of the air flow that carries away the water vapor, and the material can not come into contact with the air if necessary.

Here's what drought means:

drought gānhàn[dry spell; drought] No precipitation or too little precipitation, so that the soil weather is dry to overcome drought and win a high yield Drought usually contains two meanings: one is arid climate, which refers to a climate phenomenon in a place with no precipitation or little precipitation for many years, and the World Meteorological Organization designates areas with a dryness (the ratio of possible annual evapotranspiration to annual precipitation) greater than 10 as severe drought areas or desert areas, also known as perennial drought areas.

The second is drought disaster, which refers to the phenomenon that the precipitation in a certain place in a certain period of time is significantly less than its multi-year average precipitation, resulting in greater harm to economic activities (especially agricultural production) and human life.

Drought (meteorological term) Drought refers to a climatic phenomenon in which the total amount of fresh water is not enough to meet the needs of human survival and economic development, and is generally a long-term phenomenon. Drought has been a major natural disaster facing mankind since ancient times, and even in today's advanced technology, its catastrophic consequences are still everywhere.

It is worth noting that with the economic development and population expansion of human beings, the shortage of water resources is becoming more and more serious, which has directly led to the expansion of arid areas and the aggravation of aridification, and the trend of aridification has become a global concern.

Drought refers to a long-term climatic phenomenon in which the total amount of fresh water is too low to meet the needs of human survival and economic development. It also refers to meteorological disasters that have no rain or little rain for a long time, resulting in insufficient soil moisture and damage to crop water balance and reduced yield.

It is an agrometeorological disaster that causes insufficient soil moisture and destroys crop water balance due to long-term lack of rain or little rainfall. It can be divided into three types: soil drought, atmospheric drought and physiological drought.

Soil drought is caused by a lack of water in the soil, and the plant roots do not absorb enough water to compensate for the depletion of transpiration. Atmospheric drought is a hazard caused by the dryness of the air, often accompanied by a certain amount of wind, and although the soil is not short of water, due to strong transpiration, the water supply to the plants is insufficient. Physiological drought is caused by poor soil environmental conditions that hinder the physiological processes of crops, resulting in damage and slippery damage caused by plant water balance.

The degree of damage to crops caused by drought is related to the season in which it occurs, the type, variety and growth period of crops. Early spring affects spring sowing, or causes lack of seedlings and broken ridges of spring-sown crops, and affects the normal growth of overwintering crops. The drought in July and August, in northern China, affected the normal growth of corn, sorghum and water worm celery rice, causing the bud bells of cotton to fall off.

In the south, it affects the normal grain filling of early and middle rice and the late rice you transplant to survive. The autumn drought affected the yield of autumn crops and the sowing of overwintering crops. Both the drought and the autumn drought will cause the soil to lack the bottom moisture and exacerbate the spring drought of the following year.

The ability of crops to resist drought is called drought resistance, and drought resistance varies from crop to crop.

The difference between dry and wet precipitation and dry rain is different, generally for different monsoon climates, the precipitation in the dry and rainy season changes more seasonally, the precipitation in the dry season is very small, the rainy season precipitation is a lot, and there are abrupt characteristics, while the seasonal change of precipitation in the dry and wet seasons is relatively small, showing the characteristics of gradual change. The dry and wet seasons are mainly used to describe the precipitation characteristics of the tropical monsoon climate, while the rainy season is mainly used to describe the precipitation characteristics of the tropical monsoon climate.
