How to interpret professional meteorological information and how to understand meteorological knowle

Hehe, hello, I'm sorry, I don't think this is of much use to ordinary people, just understand the weather. It's about air pressure, I've studied marine meteorology, I understand a little bit, I'm sorry, I don't know everything, if you want to ask the best to ask friends who graduated from the School of Meteorology, they are more professional. Good luck.

1. Light snow.

Light snow, generally refers to snow that does not fall much; Meteorologically, it refers to snow that falls less than or equal to millimeters in a 24-hour period. And the twentieth of the 24 solar terms, which is also light snow, usually on November 22 or 23, indicates the beginning of snowfall, and the amount of snow is small.

2. Wind erosion. Wind erosion, or the erosive action of wind, refers to the process by which surface materials are eroded, abrasive, and carried away by the force of wind. Dry soils and relatively stable winds over the surface are the main conditions for severe wind erosion to occur.

3. Warm winter. The term warm winter, which has not been defined in meteorology in the past, is a new meteorological term produced by the warming of the climate in recent years.

Referring to the concepts of warm currents, warm fronts, and warm air masses in meteorology, climate experts from the China Meteorological Administration divide the phenomenon of cold and warm winter into warm winter and cold winter, that is, when the average temperature of the entire winter in a certain region in a certain year (the national winter is from December of the previous year to February of the following year) is higher than the normal annual value or the average climate value, the region is called a warm winter in that year, otherwise it is a cold winter.

4. Frost damage. Frost damage is a kind of agrometeorological disaster, that is, the low temperature below 0 makes the crop freeze, causing damage to the crop. Frost damage to wintering crops, fruit trees and economic forests often occur.

Frost damage poses a great threat to agriculture, mainly in Northwest, North China, East China, and Central and South China in China, and the main victims are winter wheat, rapeseed, vegetables and grapes, citrus, camellia, tea trees and other economic fruit trees.

5. Rainy season. The rainy season is in the middle and lower reaches of the Yangtze River in China, Taiwan, south-central Japan and southern Korea, and there is a continuous cloudy and rainy weather phenomenon in every month.

Low pressure – less than one standard atmosphere.

Precipitation - rain, snow, dew, fog and other water that falls to the ground.

Temperature – The temperature of the atmosphere.

Humidity – the ratio of water vapor contained in the air.

Barometric pressure – the pressure exerted by the atmosphere on an object Units Pa or kiloPa wind direction – the direction in which the wind is blowing Wind – the magnitude of the wind Typhoon – a huge cyclone that arises in the Pacific Ocean The wind force is above 12 When the wind is light, it is called a tropical storm or tropical depression.

Insolation – the amount of time the sun hits the ground.

Radiation – the emphasis of ultraviolet rays contained in sunlight.

Summary. Hello dear! The bright red glow around sunrise indicates that there is already a lot of moisture in the atmosphere, and clouds have begun to invade the region from the west, which is a sign that the weather is about to turn to rain. In the east, a bright red and golden sunset indicates that the weather in the upper reaches of the west has cleared or the clouds have cracked, so that sunlight can pass through from the west to cause the sunset, indicating that the rain clouds over the land are about to move eastward or dissipate.

I hope it will be helpful to you, and you can consult me again if you have any questions.

Meteorological data refers to the perennial dominant wind direction, wind speed, air temperature, air pressure, water energy, sunshine time, relative humidity, vertical gradient of temperature and height of the bottom of the inversion layer in the monitoring area.

The diffusion, transport and a series of physical and chemical changes of pollutants in the atmosphere depend to a large extent on the local meteorological conditions at that time, so it is necessary to collect the perennial dominant wind direction, wind speed, air fullness, air pressure, precipitation energy, daily time, relative humidity, vertical gradient of temperature and the height of the bottom of the inversion layer in the monitoring area.

Summary. Remote sensing technologies, including aerial remote sensing and satellite remote sensing, are commonly used geographic information technologies to detect atmospheric conditions. In addition, weather stations, radars, anemometers, and barometric pressure sensors can be used to monitor atmospheric conditions.

Trouble a little faster, okay.

Keep it simple, not complicated.

Remote sensing technologies, including aerial remote sensing and satellite remote sensing, are commonly used geographic information techniques to detect atmospheric conditions. In addition, weather stations, radar Nengoga, Tabi anemometers, and barometric pressure sensors can be used to monitor atmospheric conditions.

First of all, remote sensing technology is a technology that uses sensors carried by satellites or aircraft to telemetry the atmosphere, which can monitor the gas concentration, cloud cover, visibility, temperature, humidity and other parameters in the atmosphere. In addition, remote sensing technology can also be used to monitor harmful substances in the atmosphere, such as others, so as to provide people with accurate information on atmospheric conditions. Secondly, the weather station network is a technology that uses sensors installed on the ground to monitor the atmosphere, which can monitor parameters such as gas concentration, cloud distribution, visibility, temperature, and humidity in the atmosphere.

In addition, a network of weather stations can be used to monitor harmful substances in the atmosphere, such as others, to provide accurate information on the state of the atmosphere. Finally, a digital elevation model is a technique that uses topographic data to monitor the atmosphere, which can estimate parameters such as gas concentration, cloud cover, visibility, temperature, and humidity in the atmosphere by analyzing topographic data. In addition, digital elevation models can also be used to estimate harmful substances in the atmosphere, such as others, so as to provide accurate information on the state of the atmosphere.

In summary, geographic information technology can be used to detect atmospheric conditions, including remote sensing techniques, weather station networks and digital elevation models. They can all help us understand the parameters in the atmosphere accurately and provide people with accurate information about the atmospheric situation.

The difference between meteorological numerical prediction and meteorologist forecast is mainly reflected in four aspects:

First of all, meteorological numerical prediction is calculated by computer programs and observation data through numerical models, while meteorologists make forecasts by making comprehensive analysis and judgment by judging the weather situation.

Secondly, the results of meteorological numerical forecasting are "quantitative", while the results of meteorologists are semi-quantitative, where quantitative refers to can be converted into numerical representations, and semi-quantitative refers to the results that are a sentence or are described in a sentence and cannot be directly converted into numerical values.

Thirdly, numerical meteorological prediction can be based on different parameters and a more accurate model can be established. The analysis and judgment of a meteorologist is limited by his or her experience and expertise. Respectfully.

Finally, the numerical prediction of meteorology can cover a large area and low-frequency analysis, while the meteorologist has a multi-functional observation platform that can provide a single spatio-temporal rapid response forecast.

Meteorology is a branch of atmospheric science that includes atmospheric chemistry and atmospheric physics, with a primary focus on weather forecasting. The study of meteorology dates back thousands of years, although meteorology did not make significant progress until the 18th century. In the 19th century, after the formation of weather observation networks over a wide area, some progress was made in this field.

Previous attempts at weather have relied on historical data. It was not until the second half of the 20th century, when the laws of physics were elucidated, especially the development of computers, which made it possible to solve many equations that simulated the weather, and that major breakthroughs were made in weather forecasting. An important area of weather forecasting is marine weather forecasting, as it deals with marine and coastal security, where weather impacts also include the interaction of the atmosphere with large bodies of water.

Meteorological phenomena are observable weather events explained by meteorology. Meteorological phenomena are described and quantified through the variables of the Earth's atmosphere: temperature, air pressure, water vapor, mass flow, and the changes and interactions of these variables, as well as how they change over time.

Different spatial scales are used to describe and ** local, regional, and global weather.

Meteorology, climatology, atmospheric physics, and atmospheric chemistry are sub-disciplines of atmospheric science. Meteorology and hydrology constitute the interdisciplinary field of hydrometeorology. The interaction between the Earth's atmosphere and oceans is part of a coupled air-sea system.

Meteorology has applications in many different fields, such as military, energy production, transportation, agriculture, and construction.

The word meteorology comes from the ancient Greek metéros (meteor) and -logia (-(o)logy) disciplines), which means "the study of things in the sky".

Meteorology is a discipline that takes the atmosphere as the object of study, explains the characteristics of the atmosphere from both qualitative and quantitative aspects, and focuses on the study of the weather conditions and changes of the atmosphere and the forecast of the weather. Hope.
