Meteorological departments usually refer to weather greater than or equal to several degrees as high temperature weather.

1. Hazards of high temperature weather

High temperature weather will pose a great threat to people's health, easily leading to heatstroke, syncope, heatstroke failure and other diseases, and even life-threatening. Exposure to high temperature for a long time will also have a negative impact on people's psychology and emotions, causing anxiety, depression and other problems.

High temperature weather will also have a serious impact on crop growth and ecological environment, leading to crop yield reduction, drought, desertification and other problems.

2. Monitoring and forecasting of high temperature weather

Meteorological departments monitor high temperature weather in real time by monitoring ground observation stations and satellite data, and make forecast and analysis. Reduce disaster losses and casualties through measures such as high temperature warning and disaster response. Among them, high temperature days, daily maximum temperature, relative humidity, wind speed and visibility are the main indicators to evaluate high temperature weather.

3. Measures to deal with high temperature weather

In hot weather, people need to take a series of countermeasures, such as avoiding going out in high temperature and reducing the intensity of outdoor physical activity. At the same time, we should also pay attention to diet and water intake, drink plenty of water, eat light and digestible food and keep healthy. In agriculture, measures such as irrigation, mulching and shading are needed to increase the drought resistance and adaptability of crops and ensure the production and harvest of crops.

4. The influence of high temperature weather

High temperature weather will have different degrees of impact on social economy, such as transportation, energy supply, leisure tourism, health and epidemic prevention and other fields. At the same time, it will also lead to physical injury and fatigue of front-line workers and laborers, affecting work efficiency and production quality.

Under the background of global climate change, high temperature weather occurs frequently, so effective coping strategies are needed to promote energy conservation and emission reduction, build a green city and protect the environment.

5. Mitigation measures for high temperature weather

In urban planning and construction, many ways can be taken to alleviate the influence of high temperature weather. Such as increasing green vegetation, building waterscapes, fountains and other water landscapes, and improving the reflective ability of buildings. These measures are helpful to adjust urban temperature and humidity and improve urban living environment.

At the same time, technology can also be used to alleviate the impact of high temperature weather. For example, using smart air conditioning, solar water cooling system and other technologies to improve the comfort of residents' living and working environment and reduce urban energy consumption and carbon emissions.

6. Trend and forecast of high temperature weather

In recent years, meteorological data show that global high temperature weather events occur frequently. Scientists believe that this is related to global climate change and greenhouse effect. If global greenhouse gas emissions continue to increase, high temperature weather may continue to appear, and its intensity and duration will intensify. Therefore, it is of great significance to prevent and mitigate the impact of high temperature weather on human life and natural environment.

High temperature weather has great influence on human life and natural environment. In order to prevent and mitigate the adverse effects of high temperature weather, we need to take scientific and pragmatic measures, strengthen early warning and monitoring, build green and sustainable cities and communities, advocate low-carbon lifestyles, rationally utilize natural resources, and promote global emission reduction and cooling.
