The meteorological characteristics of high temperature and high humidity operation are as follows

The meteorological characteristics of high temperature and high humidity operations mainly include the following aspects:

1. High temperature:

High temperature operation means high ambient temperature, and there may be high temperature weather beyond the normal range. High temperature weather can make people feel tired easily and lose water too quickly, thus increasing health risks such as heatstroke and dehydration. In addition, high temperature can easily lead to safety problems such as fire and heat source explosion.

2. High humidity:

High-humidity operation means that the environment is humid and there is a lot of water in the air. High humidity environment will make it difficult for the human body to dissipate heat, which will easily lead to the accumulation of heat in the body, the increase of body temperature and heart rate, and further aggravate fatigue. High humidity can also easily lead to moist and airtight skin, increasing the risk of skin diseases.

3. The air is not circulating:

High temperature and high humidity working environment usually lacks air convection, so it is difficult to effectively discharge heat and moisture in the air. This will make the temperature and humidity in indoor or closed workplaces more concentrated and accumulated, which will aggravate the risk of heatstroke and dehydration.

In a high-temperature and high-humidity working environment, attention should be paid to preventing health problems such as heatstroke and dehydration. If necessary, take cooling and ventilation measures to maintain air circulation. At the same time, it is necessary to strengthen the health monitoring and training of employees, provide enough drinking water and rest time, and equip them with corresponding protective equipment to ensure the safety and health of employees.

Causes of high temperature weather:

1, solar radiation

In summer, the direct point of the sun gradually moves from south to north, and in summer, it directly hits the Tropic of Cancer. In this process, the solar altitude angle in the northern hemisphere gradually increases, the sunshine time is longer and longer, the received solar heat is gradually increased, and the temperature is also increased. This is the basic cause of high temperature weather.

2. Atmospheric circulation

On the one hand, the specific circulation situation is easy to form high temperature weather. A typical example is the subtropical high with the title of "high temperature messenger". In midsummer, the western Pacific subtropical high controls the middle and lower reaches of the Yangtze River in China. Due to the subtropical high prevailing downward airflow, the air is strongly heated.

3. Geographical factors

The geographical location, topography, landforms and other characteristics of a place will also affect the temperature. For example, in the "history" of China, there have been three big stove cities: Nanjing, Wuhan and Chongqing.

4. Global warming

Due to the influence of human activities and natural climate fluctuations, the global average surface temperature has been on the rise in recent 130 years. In the past few decades, the temperature in every decade is obviously warmer than that in the last decade. Under the influence of global warming, extreme high temperature events become more and more frequent.

5. Urban heat island effect

Due to the dense population and large building area of the city, the humidity and air convection of the urban surface have changed, resulting in the temperature in the city being significantly higher than that in the surrounding areas.
