What is the function of meteorological phenomena?

The weather is closely related to human activities. The more developed the social economy is, 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 in the exploration and research of weather phenomena and created many anecdotes about meteorology.

Meteorology can help people solve crimes. Since 1973, David Murdoch, a meteorologist at the Ontario Meteorological Center in Canada, has provided reliable evidence for 400 criminal and civil court cases in Canada and the United States, uncovered many mysteries and helped solve them.

1978 In February, an 8-year-old girl from Canada disappeared for 4 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 her face was covered with a layer of crystals produced by melting and freezing snow. He concluded that after the girl died, the temperature had risen above 0℃, so that the surface melted and the air temperature rose. Later, the temperature dropped again, and 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 body with a handbag next to it. There is a folded plastic rain hat with water vapor on it. The police invited Murdoch, who checked 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.

1978 In the summer, there were many mysterious forest fires in Ontario, which destroyed tens of thousands of hectares of forests. People suspected arson 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. Through the analysis of "fire point" and meteorological records, it is known that tourists drive to the side of the road with the engine running, enjoy the scenery and take 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 "Meteorological 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 kind of "living weather report", which guides customers' unconscious buying behavior according to the change of season or climate. This report classifies 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; On sunny days, off-road vehicles sell much; Warm air heaters are particularly popular in early winter or when the cold current comes; Hot pot sells well in winter, and the sales of aprons, chairs, orange juice and tofu will also increase. The company's meteorological analysis results are very accurate.

Mitsubishi Corporation and Mitsubishi Dentsu cooperated to produce and publish a sales trend forecast report based on the analysis of meteorological information, and faxed it to supermarket users in four major regions of China twice a day.

At present, there are more than 10 companies operating such services in Japan, and the meteorological information provided is very helpful to the actual sales activities and is welcomed by enterprise users.

In a supermarket in Australia, a manager made a fortune by selling watermelons. In the past two years, due to the long duration of high temperature in summer, some big cities are in short supply of melons and fruits, but this manager has ample supply, strong market and rolling financial resources. In the third year, some fruit company managers followed suit and ordered watermelons in large quantities, but he bought watermelons in large quantities. This year, the weather is cool and the time is long. Only he is not worried about the unsalable watermelon. It turns out that this is a great help from commercial meteorology. By studying the relationship between meteorology and commodity demand, he can predict the demand of commodities, accurately judge the market, draw an objective production, procurement and sales plan, and obtain the greatest economic benefits.

In recent years, experts and scholars in some countries have conducted a large number 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 established rapidly in some countries, looking for unfavorable climatic factors related to human health and making medical meteorological forecast. 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. Patients with heart disease and hypertension should not go out." Or: "Patients with hypertension, asthma, gallstones, etc. Please pay attention to the changes in his condition and do a good job in prevention. " After hearing this forecast, hospitals and sanatoriums immediately take strict medical monitoring measures for patients and adopt various physical therapy methods according to different situations to reduce the development of diseases caused by changes in climate and meteorological conditions.
