Global experience one of the "hottest July"!High temperature above 40 ° C in northern West Asia and Africa continues!

Recently, my country has continued to be extremely high -temperature weather, and the Central Meteorological Observatory has continuously issued high -temperature red warnings. Not only China, but also many countries around the world have also been attacked by high -temperature heat waves.

Why are there high -temperature weather in many Congress now? How long will the high temperature last? The reporter interviewed Niu Ruoyun, the chief forecast at the Central Meteorological Observatory.

Central Meteorological Observatory expert interprets global high temperature weather

On August 9th, the latest report released by the World Meteorological Organization (WMO) pointed out that this summer has experienced rare high temperature and heat in history this summer. In July, it has become one of the hottest three July since the meteorological record. According to the data of the Central Meteorological Observatory, in the past 10 days, high temperature weather above 35 ° C in Western Asia, southern Central Asia, northern Africa, Southern Europe, Western Europe, southern North America, and northern South America; Continuous high temperature above 40 ° C.

Niu Ruoyun introduced that the recent large -scale high temperature in the world is mainly caused by the effects of subtropical high pressure, and some areas are formed by the high -pressure spine that is superimposed with the high pressure of the subtropical high pressure. Recently, the northern hemisphere has a strong high -pressure high -pressure high -pressure, almost around the earth for a week, only a significant break in the area near India. Northern and southern China and Africa are also under the control of subtropical high -pressure in the southern hemisphere.

In the next 10 days, there will still be high temperature weather in South America, northern Africa, West Asia, and Central Asia. Northern South Asia is intermittent high -temperature weather. From August 18th to 21st, high -temperature weather process in South Europe and Central Europe. Before the 17th, the Midwest of the United States continued to be high -temperature weather, and the scope was still large. After the 18th, the high -temperature range decreased.

It is expected that from the 14th to 15th, there will be high temperature weather in central and southern West Asia, western Central Asia and other places, and the highest temperature in the area can exceed 45 ° C. From the 14th to 16th, there are high -temperature weather in central Brazil, southern Western Europe, and western southern Europe; the central and southern United States, northern Mexico and other places continue to be high -temperature weather. There are high -temperature weather in northern West Africa and other places, and the maximum temperature in some areas can exceed 44 ° C.

Chen Lijuan, chief forecaster of the National Climate Center, said that the sixth evaluation report of the Special Committee of the UNMA (IPCC) pointed out that in the context of global warming, since the middle of the 20th century Among them, frequent high -temperature heat waves are a very significant feature. The high -temperature heat wave event will become a new normal. It is expected that the frequency of high temperature in high temperature in summer will appear more frequently in the future, and the characteristics of long temperature duration may become more and more obvious.
