The World Meteorological Organization predicts that there will be record-breaking high temperatures this summer. What is the basis?

Rare high temperature? 、? Extreme weather? 、? Since records began? In recent years, the frequency of these words has increased. What is the reason?

The World Meteorological Organization (WMO) released a message on May 26th, saying that as the northern hemisphere enters summer, it may encounter the hottest high temperature weather on record, which will increase the medical burden, which is not conducive to the current fight against the epidemic, and calls on all countries to be prepared.

Will there really be another record-breaking high temperature weather in 2020?

As we know, there are many factors that affect the appearance of high temperature weather, such as being called? The hottest year in history? 20 16 high temperature weather is affected by super El Nino phenomenon. 20 16 is the hottest year since the instrument was recorded, and the global sea surface and land surface temperatures have broken records for 14 months. Although affected by the super El Ni? o phenomenon, the reason behind it is global warming, which leads to frequent extreme weather.

Shortly after 20 16, 20 19 was the second hottest year since the instrument was recorded. By the end of 20 19, the global average temperature will be higher than that before industrialization 1. 1 Celsius. It is worth mentioning that 20 15-20 19 is the hottest year since the instrument was recorded. What will happen in 2020?

According to the forecast of the World Meteorological Organization, record-breaking high temperature weather may come in 2020. On February 9, 2020, Seymour Island near the Antarctic Peninsula broke another record, with a high temperature of 20.75℃, the highest temperature ever measured. Moreover, 65438+ 10 in 2020 is still the hottest January since meteorological records were recorded. According to the previous temperature data 14 1 kept by the National Environmental Information Center of the United States, the global average sea and land surface temperature 1. 1.4 degrees Celsius in 2020 is higher than that in the 20th century.

What weather disasters will the temperature rise bring?

Heat wave, forest fire, rainstorm, flood, tropical cyclone, frequent diseases and so on.

High temperature weather affects human health, the most direct thing is heatstroke, and it may also induce other diseases. Judging from what happened in previous years, such as the 20 10 heat wave that swept through Russia and the Middle East, thousands of people died. July 20 18, a heat wave of 48 degrees Celsius swept through California, and the city of Chino in the United States set a record high temperature. The heat wave that swept through Japan in 20 19 caused more than 0/00 deaths and tens of thousands of people were hospitalized for heatstroke. India, Europe and Australia have all experienced record-breaking high temperatures and heat waves.

The picture shows the number of natural disasters from 1980 to 20 16.

Global temperature rise leads to an increase in the number of extreme weather.

As we all know, tropical cyclones pose the greatest threat to the life of coastal residents. Typhoons and hurricanes are tropical cyclones. Although they are two different names, they are called differently just because they are produced in different sea areas. For example, tropical cyclones generated in the Pacific Ocean are called typhoons, and tropical cyclones generated in the Atlantic Ocean are called hurricanes. Whether it is a typhoon or a hurricane, they need to get energy from evaporated seawater, and warmer oceans will provide them with more energy, thus making tropical cyclones more powerful and destructive.

High temperature weather causes drought, which is easy to cause forest fires, and other places may cause floods due to heavy rains. High temperature weather and heat wave pose a great threat to the power supply network, and the sudden increase of strong convective weather such as hail, thunderstorm and strong wind has also caused serious property losses.

Global warming will continue, and it seems only a matter of time before the current high temperature record is broken again.
