Write a paragraph on the topic of "weather phenomenon"

People live at the bottom of the atmosphere, and the four seasons in the atmosphere, wind, frost, rain and snow all have various effects 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, altitude sickness, air conditioning disease and fan disease are also related to climate. In order to meet the needs of residents to prevent and treat diseases, prolong life and improve the quality of life, meteorological departments in Beijing, Shanghai, Nanjing and other cities have carried out medical meteorological forecasts such as human comfort, heatstroke index, cardiovascular and cerebrovascular diseases, gastrointestinal infectious diseases, ultraviolet intensity and pollen concentration. 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 people's rational utilization of climate resources, disease prevention and fitness. Humans are also animals that love light. We often bask in the sun, and the sunshine in the room is good, which can not only sterilize and reduce diseases, but also help to absorb trace elements such as calcium and improve physical fitness. Therefore, how to make full use of lighting resources should be fully considered in urban planning and architectural design. As we all know, people should make rational use of climate resources to carry out sports, and climate conditions should be considered when holding large-scale sports. Sports meteorologists have studied and summarized the influence of various climatic factors on 20 kinds of sports competitions, among which wind, temperature, precipitation, fog and air pressure have the greatest influence on athletes' physical fitness and performance. Therefore, it is the host's obligation to provide all participants with the climate background information of the competition site and provide weather forecast service in time during the Games. After analyzing the climatic conditions of previous Olympic Games, domestic experts in this field concluded that Beijing's golden autumn climatic conditions were first-class in previous Olympic Games, which also contributed to Beijing's bid for the Olympic Games. In an era when people use cars, horses, sedan chairs and boats instead of walking, it is self-evident that traffic is affected by climate. The difference of transportation modes of "south ship and north horse" is the most prominent result of climate impact. In modern society, cars, trains, ships and planes are fast and convenient, but their dependence on climatic conditions is more obvious. Fog, strong wind, heavy rain, low temperature and ice and snow accumulation cause tens of thousands of traffic accidents every year, and car accidents and shipwrecks are inevitable, causing incalculable losses to the country and people. How to make rational use of climate resources, reduce traffic accidents and ensure traffic safety has always been the focus of the transportation department.
