What is the weather controlled by subtropical high?

The weather controlled by subtropical high is sunny and hot.

The formation and maintenance of subtropical high is related to the earth's rotation and latitude gradient. The subtropical high is strong in summer, because the solar radiation is strong at this time, and the surface heating causes the air to rise, thus forming a high-pressure system in the upper atmosphere. This high pressure system will move to low latitudes, bringing sunny and hot weather.

Subtropical high, also known as subtropical high, is an atmospheric circulation system, which has an important influence on the weather pattern on the earth. It is usually located between 30 and 40 latitudes, and it is a deep cyclone high pressure system. The weather characteristic controlled by subtropical high is sunny and hot weather.

Under the control of subtropical high, airflow usually diverges from the center of high pressure, resulting in downward airflow. Downward airflow will inhibit the formation of clouds, so the area controlled by subtropical high is often sunny and sunny. At the same time, due to the existence of downward flow, the air will be heated during the sinking process, which will raise the temperature and form sunny and hot weather.

Subtropical high not only affects temperature, but also affects precipitation. At the eastern edge of the subtropical high, a frontal area is often formed, with strong updraft and easy precipitation. In the high-pressure central area, due to the strong downward flow, less precipitation and sunny weather.

Generally speaking, the weather controlled by subtropical high is sunny and hot. This kind of weather has an important impact on agricultural production, energy consumption and people's lives. However, subtropical high will also bring some adverse effects, such as drought and high temperature, so the research and monitoring of subtropical high is of great significance for understanding and predicting weather changes.

Characteristics of sunny and hot weather

1, sunny: sunny and hot weather with strong ultraviolet radiation. The sun shines for a long time and the ground gets enough solar energy, which makes the temperature rise rapidly.

2. High temperature: In sunny and hot weather, the temperature is usually high, and it can reach the highest value at noon. Due to the accumulation of surface heat, the temperature drop at night is small, so the temperature difference between day and night is small.

3. Sparse precipitation: sunny and hot weather is usually related to the subtropical high system, which will lead to sparse precipitation. Air subsidence inhibits the development of cloud system, so the sky is clear and the probability of precipitation is low.

4. air drying: due to less precipitation, the air humidity is low. In this case, the evaporation of human sweat is accelerated, which easily leads to water loss, so pay attention to sun protection and hydration.
