Why is weather closely related to us?

1. People live at the bottom of the atmosphere. Seasonal changes, wind, frost, rain and snow in the atmosphere have various effects on the human body, and even cause diseases. Some of them are directly or indirectly caused by climate conditions, such as heatstroke, frostbite, colds, chronic bronchitis, joint disease, cardiovascular and cerebrovascular diseases, etc.; in addition, altitude sickness, air conditioning disease, fan disease, etc. are also related to climate. Of course, proper use of climate conditions can also prevent and treat diseases, such as using climate conditions as a means of physical exercise, mountaineering, winter swimming, skating, skiing, etc. to enhance physical fitness; climate recuperation, such as sand therapy, sunbathing, air baths, cold water baths, etc. Methods of disease prevention and treatment have been accepted by more and more people; weather forecasts such as clothing index and mountain climbing index have played a guiding role in people's rational use of climate resources, disease prevention and fitness;

2. Climate resources are one of the most important components of natural resources that affect agricultural production. The energy and materials they provide such as light, heat, water, and air have important impacts on agricultural production types, planting systems, layout structures, production potential, Development prospects, as well as the quantity, quality and distribution of agricultural, forestry and animal husbandry products all play a decisive role;

3. Climate change usually changes the status quo of the global hydrological cycle, increasing the intensity and frequency of hydrological events. This in turn affects the design, operation and construction materials of large-scale water conservancy projects;

4. In an era when people travel by cars, horses, sedans, and boats, transportation is also greatly affected by climate; "Southern Ships and Northern Horses" The difference in transportation modes is the most prominent result of climate impact. In modern society, transportation such as cars, trains, ships, and airplanes are fast and convenient, but their dependence on climate conditions has become more obvious. It can be seen that climate plays an important role in human activities. It has a great impact on daily life, agricultural production, water conservancy construction, urban construction, sea, land, air, military, and transportation.
