What do you mean, clean up?

Clearing up is a meteorological term, which refers to the phenomenon that the weather changes from rainy days to sunny days.

Clearing up is usually due to the influence of air pressure and high pressure system, which leads to the gradual dispersion of clouds and the transparent and bright sky. The sun can shine directly on the ground, and the temperature often rises, which makes people feel warm and comfortable. In the weather forecast, clearing up is usually a good forecast, because it means that the weather will obviously improve, suitable for outdoor activities and travel. Sunbathing will also have a positive impact on agricultural production, transportation and other industries, but if it is too sunny, it may also cause problems such as drought.

Cleaning also plays a very important role, which is to ease people's emotions and make people feel happy. In gloomy weather, people's mood often becomes low and depressed, but when sunny days come, sunshine and beautiful weather will bring joy and vitality. In ancient culture, tidying up is often regarded as a symbol of good luck. In the traditional culture of China, quietness is regarded as a good omen for harmony between heaven and earth, national prosperity and people's safety, especially in important festivals and festive activities, quietness is what people expect and pray for.

Under the social background of increasing concern for environmental protection, cleaning is also closely related to reducing air pollution and improving the ecological environment. Therefore, cleaning is also regarded as a sign of environmental health and improvement. The government and all walks of life need to take measures to strengthen environmental protection, ensure environmental quality such as air and water quality, and establish a more beneficial natural ecosystem while ensuring people's health and the environment.

How did the weather change come about?

1. temperature: when the temperature rises or falls, it will affect the way of air activity. For example, rising temperature will affect the time, quantity and ecology of water, plants and animals, and falling temperature will also affect the existence of surface materials, such as ice, snow and rivers.

2. Humidity: Humidity refers to the moisture content in the air. The change of humidity will affect the density of air, thus affecting the change of air pressure, and also affecting the formation of clouds and precipitation.

3. Air pressure: Air pressure represents the density of air, and the change of air pressure affects the movement of air, thus affecting the change of weather.

4. Wind speed and direction: the change of wind speed and direction depends on the change of air pressure, which is related to meteorological factors such as temperature and humidity. The change of wind will affect the shape and movement of clouds, as well as the climate of the ocean and land.

5. Precipitation: The change of precipitation will affect the structure of buildings, the distribution of water resources, the water demand of plants and so on, which is a very important aspect of weather changes.
