North China is hotter than South China this summer. What is the reason?

The reason is influenced by climate, airflow and altitude. Because North China belongs to the northern hemisphere, although the latitude is relatively high, the altitude is low, which leads to high temperature weather. The specific reasons are as follows:

1, climate and monsoon system:

North China is located in the north of China, which belongs to the temperate monsoon climate zone. This summer, affected by the continental high, dry and hot weather often appeared in this area. In contrast, the southern region is closer to the tropical region, usually with more rainfall and humid climate.

2, airflow and meteorological system:

After North China is affected by the continental high this summer, the continental high will gradually move eastward with the warm air mass controlled by the ridge of high pressure, directly expanding the high temperature area. This time, the high temperature weather in North China was not only controlled by the continental high pressure, but also influenced by Taihang Mountain.

When the continental high pressure carries the warm air mass across the mountains and into the plains, it will produce the wind-burning effect and aggravate the temperature rise, so there will be high temperature weather in North China.

3. Topography:

North China is relatively flat and lacks large water bodies or mountains, which may lead to terrain uplift and weak air convection, limiting the air mixing and cooling effect. In contrast, there are mountains, water bodies and other natural landforms in the southern region, which contribute to the uplift and convection of air and bring a certain cooling effect.

4. Urbanization and heat island effect:

The degree of urbanization in North China is relatively high, and factors such as buildings, population and traffic in the city will lead to the occurrence of urban heat island effect. Urban heat island effect refers to the phenomenon that the temperature in urban areas is significantly higher than that in surrounding rural areas. Buildings and roads in cities store and release heat, coupled with high population density, resulting in relatively high temperatures in urban areas.

Measures to prevent high temperature weather:

1, keep drinking water:

In hot weather, the body is easily dehydrated. To ensure adequate water intake, drink plenty of water and cool sugar-free drinks, and avoid caffeine and alcoholic drinks, as they may accelerate dehydration.

2. Avoid going out during hot hours:

Try to avoid going out in hot noon, when the temperature is usually the highest. Choose outdoor activities in the early morning or evening, when the temperature is relatively low.

3, breathable, light:

Choose breathable, loose and lightweight clothes, which can dissipate heat and reduce sweat evaporation. Avoid wearing black or dark clothes, because they will absorb more calories.

4. Use sunscreen and shading tools:

When you are outdoors, apply sunscreen to protect your skin from ultraviolet rays. Wear a wide-brimmed hat, sunglasses and parasol to provide additional sun protection and shade protection.

5. Avoid strenuous exercise:

Avoid strenuous exercise in hot weather, especially at noon and afternoon. If you need physical exercise, choose to do it in the morning or at night when the weather is cool, and pay attention to moderate rest and hydration.

6. Find a cool place:

When the weather is hot, find a cool place to avoid direct sunlight, such as under the shade of trees, indoor air-conditioned environment or outdoor cool water. Use a fan, air conditioner or wet towel to reduce the indoor temperature.
