What is the role of meteorological phenomena?
The weather is closely related to human activities, and the more developed the social economy, the more we need to understand the weather changes. Not only the needs of industry, agriculture, animal husbandry, fishery, construction, aviation, navigation, public utilities, military and other departments, but also commerce, culture, sports, medical care and so on are greatly affected by the good or bad weather.
In recent years, people have searched for meteorological laws and created many anecdotes about meteorology in the exploration and research of weather phenomena.
meteorology can help people solve crimes. David Murdoch, a meteorologist at the Ontario Meteorological Center in Canada, has provided a reliable basis for 4 cases in criminal and civil courts in Canada and the United States since 1973, uncovered many mysteries and helped solve the cases.
In February p>1978, an 8-year-old girl in Canada disappeared for four days, and her body was found in the snow. There is not enough evidence to arrest the suspicious man. The police invited Murdoch. He carefully examined the girl's body and found that the girl's face was covered with a layer of crystals produced by melting and freezing snow. He concluded that after the girl's death, the temperature had risen above ℃, so that the surface melted and the air temperature increased. Later, the temperature dropped again, so it condensed into crystals on the bare face. He checked the recent weather records and confirmed that the girl's death time was about two hours after her disappearance, thus solving the case.
In a park in Toronto, people found a female corpse with a handbag next to it, and there was a folded plastic rain hat with water vapor on it. The police invited Murdoch, who consulted the rain radar records and knew that it was raining in only two areas of Toronto when the woman died. The police immediately investigated the suspicious situation in these two areas, and a few hours later, they caught the murderer.
In the summer of p>1978, there were many mysterious forest fires in Ontario, which destroyed tens of thousands of hectares of forests. People suspected that someone had set fire and sent experts to the scene to investigate, including Murdoch. According to meteorological records, the weather is fine every time there is a forest fire. After the analysis of the "fire point" and meteorological records, it was known that tourists drove their cars to the side of the road with the engine running, enjoying the scenery and taking pictures. The thermal radiation from the catalytic converter in the anti-pollution device under the automobile chassis scorched the grass on the roadside. When the tourists drove away, the hay burned under the breeze and gradually spread into a forest fire.
Because of Murdoch's brilliant achievements in solving crimes, he became the first internationally recognized expert in the world and was known as "Weather Sherlock Holmes".
with the development of the times, the influence of meteorology on business is increasing. There is a company in Japan, whose main business is shop design, sales planning and market research. There is a "Life Weather Report", which leads customers to unconscious buying actions according to the changes of seasons or climate. This report classifies the factors such as temperature, humidity and sunshine, and analyzes the relationship between meteorology and commodity sales. For example, whenever there is a typhoon or rainy weather, the sales of dry batteries will surge; In sunny weather, off-road vehicles sell a lot; The heater is especially popular in early winter or when the cold current comes; In winter, when the hot pot sells well, the sales of aprons, chairs, orange juice and tofu will also increase. The meteorological analysis results made by this company are highly accurate.
Japan's Mitsubishi Corporation and Mitsubishi Dentsu cooperated with each other to produce and distribute the Sales Trend Forecast Report based on the analysis of meteorological information, which was faxed to supermarket users in four major regions of China twice a day.
At present, there are more than 1 companies operating such services in Japan, and the meteorological information provided is very helpful to the actual sales activities, which is welcomed by enterprise users.
In a supermarket in Australia, a manager made a fortune by selling watermelons. For two years, due to the long duration of high temperature in summer, some big cities were in short supply of melons and fruits, but this manager was well supplied, with a strong market and rolling financial resources. In the third year, some fruit company managers followed suit and ordered a large number of watermelons, but he bought a large number of watermelons. This year, the weather was cool and the time was long, and only he didn't worry about the unsalable watermelon. It turns out that this is a great help from commercial meteorology. He studies the relationship between meteorology and commodity demand, and can predict the demand of commodities, so as to accurately judge the market, draw objective production, procurement and sales plans, and obtain the greatest economic benefits.
In recent years, experts and scholars in some countries have conducted a lot of clinical experiments to explore the relationship between meteorological factors and people, and found out some meteorological factors that induce diseases, such as influenza, asthma, arthritis, angina pectoris, heart disease, stroke, ulcerative bleeding and so on. It is also found that meteorological factors will change blood pressure, blood composition and metabolic process, and affect people's physical strength and intelligence.
Medical meteorology has been rapidly established in some countries, looking for adverse climatic factors related to human health and making medical meteorological forecasts. For example, the weather forecast says: "Due to the influence of the heating mass, there will be high temperature weather in the next few days, and people with heart disease and high blood pressure should not go out." Or: "Patients with hypertension, asthma, gallstones, etc., please pay attention to the changes in their condition and do a good job in prevention." After hearing this kind of forecast, hospitals and sanatoriums immediately take strict medical monitoring measures for patients and adopt various physical therapy methods according to different conditions to reduce the development of diseases caused by changes in climate and meteorological conditions.
