Why is the weather closely related to us?

1. People live at the bottom of the atmosphere. The changes of the atmosphere, wind and frost, rain and snow all have various influences on the human body and even cause diseases. Some are directly or indirectly caused by climatic conditions, such as heatstroke, frostbite, cold, chronic bronchitis, arthropathy, cardiovascular and cerebrovascular diseases, etc. In addition, mountain sickness, air conditioning disease and fan disease are also related to climate. Of course, appropriate use of climatic conditions can also prevent diseases, such as using climatic conditions as a means of physical exercise, mountaineering, winter swimming, skating, skiing and so on. , enhance physical fitness; Climate recuperation such as sand therapy, sunbathing, air bath and cold water bath has been accepted by more and more people. Weather forecasts such as dressing index and mountaineering index have played a guiding role in rational utilization 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 such as light, heat, water and air it provides play a decisive role in agricultural production types, planting systems, layout structure, production potential and development prospects, as well as the quantity, quality and distribution of agricultural, forestry and animal husbandry products.

3. Climate change will usually change the current situation of global hydrological cycle, increase the intensity and frequency of hydrological events, and then affect the design, operation and building materials of large-scale water conservancy projects.

4. In the era when people travel by car, horse, sedan chair and boat, the traffic is also greatly affected by the climate; The difference of transportation mode of "south ship and north horse" is the most prominent result of climate influence; In modern society, cars, trains, ships and planes are fast and convenient, but their dependence on climatic conditions is more obvious; It can be seen that the climate has a great influence on human life, agricultural production, water conservancy construction, urban construction, land, ocean, air, military affairs and transportation.
