How do you distinguish common weather systems in practical problems?

If you don't do the questions, there is no point in doing the questions.

Common weather systems and their effects on the weather in our country are as follows:

Cyclones and anticyclones are the two most basic weather systems. In the cyclone zone, the air flow converges from the outside to the inside, and the air flow carries the water vapor in the surface air layer to rise, cools and condenses at high altitude, forming clouds and rain. As a result, the weather in the cyclone area is generally cloudy and rainy and cloudy.

In the anticyclonic zone, the airflow diverges from the inside outward, and the downdraft prevails, and the weather is generally fine.

Due to China's location in the middle latitudes, cyclonic and anticyclonic activities are quite frequent. Many of the drastic weather changes on the mainland of our country are mostly caused by cyclones and anticyclones. For example, in winter, the Mongolian Plateau in northern China is very cold, and often forms an anticyclonic high pressure center.

Once this cold anticyclone moves south, Peimu will bring a strong cold wave to the vast areas of our country, which will seriously affect the weather in our country. Another example is a typhoon, which is a very powerful tropical cyclone, accompanied by violent storms and stormy waves.

What does the weather system include:

Common weather systems include fronts, cyclones, and anticyclones. Fronts are divided into warm fronts, cold fronts, and quasi-stationary fronts. Weather system usually refers to the atmospheric movement system with typical characteristics, such as high pressure, low pressure and high pressure ridge and low pressure trough, which cause weather changes and distribution.

Weather system is an atmospheric movement system with typical characteristics divided according to the spatial distribution of meteorological elements, such as high pressure, low pressure, high pressure ridge, low pressure trough, etc. Sometimes refers to a system of wind distribution, such as cyclonic circulation, anticyclonic circulation, shear lines, etc. Sometimes it refers to a system of temperature distribution, such as high temperature zone, low temperature zone, front zone, etc.

Sometimes refers to a system in which weather phenomena are distributed, such as thunderstorms, tropical clouds, etc. There is often a certain configuration relationship between this element system and another element system.

1.Connection and Difference Between Weather and Climate: Concept:

Weather: The combination of atmospheric conditions (temperature, humidity, pressure, etc.) and atmospheric phenomena (wind, clouds, fog, etc.) in a certain area at a certain moment or in a certain period of time. Weather course:

Short-term processes in the atmosphere. Climate: The synthesis of a large number of weather processes over a period of time under the interaction of solar radiation, atmospheric circulation, underlying surface properties, and human activities over a long period of time.

Climate: the average statistical characteristics of all components of the climate system in a certain area in any given period of time ( Gates ) Differences and connections: 1. Different time scales Climate includes the weather conditions that often occur in the region over the years, as well as the occasional extreme weather conditions in certain years.

Climatic processes are long-term atmospheric processes that are synthesized from a large number of weather processes over a certain period of time. There is a statistical link between weather and climate. 2. The speed of change and the cycle are different, the weather changes quickly and the cycle is short; There are short-term weather processes, medium-term weather processes, and long-term weather processes.

The cycle of climate change is long, including interseasonal, inter-annual, inter-decade, intercentric, inter-millennium, and 10,000-year. 3. Different spatial scales The climate system (5 subsystems) is large, and the weather system (such as cyclones, anticyclones) is simple. 4. The content contained is different

Climate encompasses complex content; The weather is correspondingly simple.

Bad weather refers to climate change at the right time.

Weather system refers to the atmospheric movement system with typical characteristics, such as high pressure, low pressure, high pressure ridge, and low pressure trough, which cause weather changes and distribution. Meteorological satellite observations show that large and small weather systems are intertwined, interacting, and evolving in the process of atmospheric movement.

Weather and weather systems are the relationship between child systems and parent systems.

1 all.

First, the front system.

The interface between warm and cold air masses is called a front.

On both sides of the front, there are obvious differences in temperature, humidity, air pressure, and wind What is the highest temperature in A, B, and C? Highest air pressure?

What is the biggest change in the weather?

Near the front, it is often accompanied by clouds, rain, strong winds, etc.

A cold front and weather.

Concept: A front in which a cold air mass actively moves towards a warm air mass.

Weather: During transit: cloudy, rainy, windy, cooling and other weather phenomena often occur after transit: the air pressure rises, the temperature and humidity plummet, and the weather is sunny Graphics: Impact on our country: a, heavy rain in summer in northern China b, sandstorm weather in winter and spring in northern China.

c. The cold wave that broke out in winter in China.

Two warm fronts and weather.

Concept: A front in which a warm air mass actively moves towards a cold air mass.

During transit: Weather: The clouds are slowly thickening, mostly forming continuous precipitation, precipitation occurs before the front and after the transit: the temperature rises, the pressure drops, and the weather becomes clearer.

Graphics: Impact on our country.

Partial precipitation in the south of our country.

2. Low-pressure (cyclone) and high-pressure (anticyclone) systems.

Low pressure or cyclone, high pressure or anticyclone, respectively, are different descriptions of the same weather system.

Low pressure, high pressure is a description of the air pressure conditions of a weather system.

A cyclone, anticyclone, is a description of the airflow conditions of a weather system.

A cyclone (low pressure).

Central pressure: low pressure.

Horizontal airflow flow: counterclockwise convergence.

Vertical movement of the central airflow: ascent.

Weather conditions: southerly winds in the east and northerly winds in the west.

2. Anticyclone (high pressure).

Central pressure: high pressure.

Horizontal air flow: Divergent clockwise.

Vertical movement of the central airflow: ascent.

Weather conditions: Sunny.

Three-frontal cyclone.

Surface cyclones are generally associated with fronts.

Frontal cyclones are a common weather system in the middle and high latitudes of China.

Fronts, cyclones, anticyclones.

The contact surface when the movement of the cold and warm air masses meet is called the front, the boundary between the front and the ground is called the front, and the front and the front together are called the front.

It is also divided into warm front, cold front, and quasi-stationary front.

A cyclone is the flow of air formed by a low-pressure system, and an anticyclone is the flow of air formed by a high-pressure system.

The air temperature in the weather forecast refers to the (temperature) of the air

Air temperature: The air temperature mentioned in the weather forecast refers to the air temperature measured in the field air circulation and not directly exposed to the sun (generally measured in the louver box).The maximum temperature is the highest temperature in a day, usually at 14-15 o'clock, and the lowest temperature generally occurs at 5-6 o'clock in the morning.

1 Concept: A surface cyclone is generally associated with a front, which is called a frontal cyclone.

2 Weather: clouds rushing into the wild, rain, even torrential rain, thunderstorms, windy weather. Rantan.

Fronts, cyclones, anticyclones.

The contact surface when the cold and warm air masses meet is called the front, the boundary line between the front and the ground of the Lujing Bureau is called the front, and the front line and the front of the morning car are called the front.

It is also divided into warm front, cold front, and quasi-stationary front.

A cyclone is the flow of air formed by a low-pressure system, and an anticyclone is the flow of air formed by a high-pressure system.
