What natural phenomena can know the weather conditions all year round?

Birds and birds fly low, competing for perch, fish leap into the water when it rains, ants move, frogs chirp, dragonflies fly low, birds fly high when it rains, and seabirds fly up the river.

Ant. The ants began to move and move food. Ants are very sensitive to air pressure, temperature, humidity. Dog. "The dog is soaked in water, and it is going to rain.

Weather phenomena take the natural world as the observation goal, and some weather phenomena may cause great harm to human beings.

As follows: 1. Little swallow. Low-flying insect catcher.

There is a folk saying that "it will rain when swallows fly low". 2. Small fish. Swim out of the water to breathe.

Fish live by breathing oxygen dissolved in the water. When the atmospheric pressure is high on a sunny day, there is a lot of dissolved oxygen in the water, so it sinks quietly to the bottom of the water; Before the rain, the air pressure is low, the oxygen in the deep water is greatly reduced, and the fish come to the surface.

According to the type, it can be divided into: precipitation phenomenon; ground condensation; visual impaired phenomena; lightning phenomena; Other phenomena.

1. Precipitation phenomenon: According to the form of precipitation, it is divided into 11 kinds, namely:

liquid precipitation – rain, drizzle, showers;

Solid precipitation – snow, ice particles, rice snow, snow showers, graupel, hail;

Mixed precipitation – sleet, showers.

2. Surface condensation and freezing: including dew, frost, fog, rain and so on.

3. Visual range obstruction: including fog (fog, fog, dense fog); light mist; blowing snow; Snowstorm; Smokescreen; Haze; sandstorms (sandstorms, severe sandstorms, super-strong sandstorms); Yangsha; Dust.

4. Lightning phenomenon: thunderstorm, lightning, aurora.

5. Other phenomena: wind, squall, tornado, dust tornado, ice needle, snow, ice.

In this way, there are many common weather phenomena, and rare weather phenomena such as "solar rain", "double rainbow", and "ball lightning", no matter how unpredictable, are actually inseparable.

Weather phenomena

Various natural phenomena that occur in the atmosphere, that is, the comprehensive performance of the spatial distribution of various meteorological elements in the atmosphere (such as air temperature, air pressure, humidity, wind, clouds, fog, rain, flash, snow, frost, thunder, hail, haze, etc.) in a certain instant.

Weather processes are the process of changing weather phenomena in a certain area over time. All kinds of weather systems have certain spatial and temporal scales, and the various scale systems are intertwined and interact with each other. The combination of many weather systems constitutes a large-scale weather situation that constitutes the atmospheric circulation of the hemisphere or even the world.

Weather systems are always in the process of rebirth, development and disappearance, and have their corresponding distribution of weather phenomena at different stages of development.

Answer: 1. Little swallow. Low-flying insect catcher.

There is a folk saying that "it will rain when swallows fly low". 2. Small fish. Swim out of the water to breathe.

Fish live by breathing oxygen dissolved in the water. When the atmospheric pressure is high on a sunny day, there is a lot of dissolved oxygen in the water, so it sinks quietly to the bottom of the water; Before the rain, the air pressure is low, and the oxygen in the deep water is greatly reduced, and the fish rise to the surface to breathe.

This article mainly provides information about the climatic characteristics of the four seasons in primary science, primary school science: explain the reasons for the formation of the four seasons, which phenomena in nature are used in the text to describe the changes in the climate of the four seasons, and what are the climatic characteristics of the autumn third-grade science related content is provided by Chuzhou Meteorology, click to view details.

Common natural phenomena in the four seasons include spring breeze, summer rain, autumn frost, and winter snow. These natural phenomena are the result of the Earth's revolution and rotation, specifically:

1.Spring breeze: Spring winds are produced due to the rotation and revolution of the earth. Due to the difference in heat generated by the revolution of the earth, the air pressure is unevenly distributed, and a spring breeze is formed. Spring breezes help the temperature rise, melt the snow, and revive everything.

2.Summer rains: Summer rainfall is due to the high summer temperatures, the amount of water vapor in the air increases, and when the water vapor meets the cold air, raindrops are formed. Summer rainfall helps replenish soil moisture and sustains plant growth, and is an important part of the hydrological cycle.

3.Autumn frost: Autumn frost is formed when the temperature drops and the water vapor in the air condenses into ice crystals near the ground.

It usually occurs on clear nights, when the temperature is below freezing, and the water vapor condenses directly into ice crystals. The appearance of autumn frost marks the arrival of autumn and is also a harbinger of winter.

4.Winter snow: Winter snow is formed when the temperature drops, and the water vapor in the air condenses into snowflakes near the ground.

Snowflakes usually begin to form when the temperature drops below minus 5 degrees Celsius. The arrival of winter snow marks the arrival of winter, which provides insulation to the earth and moisture to the plants in winter.

In general, the natural phenomena that are common in the four seasons are the result of the rotation and rotation of the earth, and these natural phenomena play an important role in maintaining ecological balance and recycling natural resources.

The common natural phenomena in the four seasons are "spring birth", "summer length", "autumn harvest" and "winter storage". That is, all things are born in the spring, grow in the summer, harvest (mature) in the fall, and hide in the winter (animals hibernate, plants lose their leaves).

In meteorology, the seasons are divided according to the average temperature.

In order to accurately reflect the actual temperature changes in various places, China often adopts the classification method of modern scholar Zhang Baokun, that is, "waiting for average temperature" to divide the four seasons. The classification stipulates that the period when the average temperature is greater than or equal to 22 is summer, the period less than or equal to 10 is winter, and the period between 10 and 22 is spring or autumn.

According to this criterion, the seasons in the mid-latitudes are basically consistent with the "average temperature", and the results are usually divided into March and May for spring, June and August for summer, September and November for autumn, and December to February of the following year for winter.

This is scientific, because the weather does affect the harvest of crops, and some bad weather can cause crops to fail.

There is a certain scientific basis. This means that the weather is cyclical, if it is cloudy on the night of April 15.

There is still a scientific basis, after all, in the past, agricultural science and technology is not now developed next to the clever situation, it has a certain reference and practical value, China's 24 solar terms are also based on the weather changes wide key and the close connection of the harvest was created, these are the predecessors of the Yunkai long-term production and labor practice of the experience accumulated continuously. However, weather changes are closely related to the natural ecological environment and cannot be 100% correct.
