Northeast continues to "steam sauna"
On August 1st, the high temperature occurred in Shenyang, Liaoning Province for the fifth consecutive day. The highest temperatures in Dandong and Dalian reached 37.3℃ and 36.9℃ respectively, setting a meteorological record for extreme values. At the same time, the highest temperature in Shenyang today may reach 37℃, which will set a new record for the local extreme highest temperature in August (the previous record was 35.7℃).
Liaoning suffered the strongest regional high temperature since 1961.
In addition, with the continuous expansion of high temperature, the temperature in Changchun may reach 36℃ on the 3rd, which will not only set a new high this year, but also become the hottest day in the local observation history in August. The high temperature in Changchun in August is very rare, and there has been only one high temperature on August 3, 1968 since it was recorded in 1951.
The temperature in North China is also constant.
In addition to the northeast, Beijing-Tianjin-Hebei and northern Shandong will also have high temperatures in the next three days, and the highest temperatures in Beijing, Tianjin, Shijiazhuang and Jinan will remain at 35 C or above.
On the 1st, Beijing spent the 17th high-temperature day this year, which was the same as last year’s high-temperature days, and it was seven days short of the 24 high-temperature days recorded in 2000. Monitoring shows that the highest temperature in the observatory in the southern suburbs reaches 37℃, and that in Fengtai reaches 38.3℃.
Affected by the continuous high temperature, as of 12: 30 on the 1st, the load of Beijing power grid has reached 23.064 million kilowatts, exceeding the 22.675 million kilowatts on July 31st, reaching a new high.
The temperature in North China is high during the day and not low at night, and the lowest temperature is mostly above 26℃, and Tianjin will exceed 28℃. Moreover, due to the high relative humidity, the somatosensory temperature is higher, and the sultry feeling is not inferior to that in the south.
The Central Meteorological Observatory predicts that in five days, the hot weather in the above-mentioned areas in the north will end. This round of high-temperature weather lasts for a long time, and the high temperature in some areas breaks the extreme value. People in the above areas need to be prepared for heatstroke prevention and cooling, and try to avoid going out at the hottest noon. If they have to go out, they should take sun protection measures and replenish water in time. Outdoor workers prepare some heatstroke prevention drugs for emergencies.
The high temperature area in the south has been significantly reduced, and it has made a comeback since the 4 th
For many places in the south that have been suffering from high temperature for nearly half a month, they will enjoy a short coolness in the past two days. Affected by a wide range of rain and the wind and rain brought by the typhoon "Lark", the high temperature area in the south will continue to shrink in the past two days.
On the 2 nd, the western and southern parts of Jiangnan and most of southern China withdrew from the high temperature. On the 3rd, only parts of northern Chongqing, northeastern Hubei and northwestern Jiangxi still have a small range of high temperatures, and the rest areas will basically end the high temperatures temporarily. In the area of Jiangsu, Zhejiang and Shanghai, the highest temperature in many places dropped to around 30℃.
Although the high temperature in the south has shrunk, the highest temperature in many places is still around 33℃, and the sultry feeling will continue. At the same time, the cooling time is very short. Starting from the 4th, the high temperature in the south will return strongly. At present, it is in the middle of the sky, and high temperature is the main theme. People in the southern region need to continue to prepare for heatstroke prevention and cooling.

The World Meteorological Organization issued statements on July 26th and 27th, respectively, saying that extreme weather events such as high temperature, drought and catastrophic precipitation occurred one after another in many places around the world, among which drought and high temperature also aggravated the wildfire disaster in the northern hemisphere. These extreme weather have brought great adverse effects on human health, agriculture and ecosystem.

It’s hot in the North Pole, too! Rare high temperature in Arctic Circle
From June to July this year, the temperature in many places around the world, including the Arctic Circle, generally rose, resulting in extremely hot weather.
Recently, the temperature in the Arctic Circle in northern Sweden once reached 30℃. In northern Siberia, the temperature reached 32℃ at the beginning of this month. In the same period of last year, the average temperature in this area was only 10℃.
According to the monitoring data of the National Snow and Ice Data Center of the United States, the abnormal high temperature further aggravated the sea ice melting phenomenon in the Arctic Circle this summer, and the sea ice in the northern European coast and northwestern Russia has shown an abnormally low trend. The decrease of sea ice will not only threaten the survival of polar bears and other creatures, but also further aggravate the abnormal weather in the northern hemisphere.
Europe suffers from high temperature and drought.
In addition to western Europe and southern Europe, which suffer from heat waves, northern Europe is also experiencing continuous high temperatures. In July, the temperature in the Arctic Circle reached 30℃. On July 17th, the temperature in parts of Norway reached a record 33.5℃. Due to the unusually dry and warm climate, forest fire risks in Scandinavia and the Baltic Sea continue to rise. There were about 50 forest fires in Sweden in mid-July. The World Meteorological Organization predicts that the temperature in northern Europe will be 3℃ to 6℃ higher than that in the same period of last year.
The temperature in Sweden reached 86 degrees Fahrenheit (30 degrees Celsius) in July, and there were more than 50 forest fires, of which more than 10 occurred in the Arctic Circle. (Source: Beijing News)
There are high temperatures above 30℃ in many places in Britain, even as high as 38℃. In addition, the weather in Britain is extremely dry. By the end of July, there was no rain in many places in Britain for nearly two months, and the rainfall was only 47 mm after the summer, making it the driest summer in the past 57 years. According to the statistics of the British medical department, thousands of people died of diseases related to high temperature this summer.
The Asian heat wave struck, and many people died in Japan, South Korea and other countries.
Japan has recently been hit by a heat wave after the worst rainstorm and flood in decades. Due to the control of a wide range of high pressure, the temperature in Japan has repeatedly set a new record. On July 15th, the highest temperature of 200 meteorological observation stations of Japan Meteorological Agency exceeded 35℃. On July 23rd, the highest temperature of 41.1℃ was observed in Kumagaya, saitama, and high temperatures exceeding 40℃ were also observed in Qingmei City, Tokyo, Jiafu City, Yamanashi Prefecture and Tojima City, Gifu Prefecture. According to the statistics of Kyodo News Agency, from July 16 to 25, more than 22,000 people in Japan were sent to hospital for heatstroke, of which 78 people died of heatstroke.
South Korea’s extensive high-temperature weather continued, and the Korea Meteorological Agency issued a high-temperature warning for several days. Statistics from the Korea Disease Management Headquarters from May 20th to July 21st showed that there were 1043 people suffering from heatstroke, up 61% year-on-year. More than ten people have died of heatstroke this year. The South Korean government is considering classifying extreme heat as the same category of natural disasters as typhoons, floods, tsunamis and earthquakes.
According to the news from the Central Meteorological Observatory of North Korea, high temperature began to appear in North Korea on July 15th, and the scope gradually expanded. On July 22nd, the average highest temperature in North Korea reached 34.6℃, 7.2℃ higher than in previous years, the highest temperature since 1981. Among them, the average temperature in several big cities is higher than 39℃, and Yuanshan City has reached.
The high temperature in Africa and North America is over 50℃ in some areas.
At the beginning of July, several North African countries also experienced heat waves. On July 5th, the highest temperature in Valgra in the Sahara Desert of Algeria reached 51.3℃. According to the World Meteorological Organization, this is the highest temperature since Algeria has reliable temperature records. On July 3, Morocco monitored a high temperature of 43.4℃.
At the same time, North America has not been spared. California suffered a record high temperature, and the highest temperature records in many cities were refreshed. Death Valley National Park in California, which set a record for the highest temperature in the world at 56.7℃ in July 1913, has observed a high temperature of 52℃ on July 8 this year. The highest temperature in Chino, a suburb of Los Angeles, reached a record 48.9℃. In Quebec, Canada, hot and humid weather caused dozens of deaths, including the elderly and the vulnerable.
On July 6, 2018, California, USA, a heat wave of 48℃ swept through southern California, and the heat index off the charts set a new record. People gathered in Huntington Beach to play in the water to cool off the heat. (Source: Oriental IC)
High temperature and drought aggravate wildfire disaster in the northern hemisphere
According to a statement issued by the World Meteorological Organization on July 27th, many serious wildfires have occurred in Siberia, Sweden, Greece, the United States, Canada and other places since the summer of this year due to high temperature and drought, and the fire area is still increasing.
According to the monitoring data of Fengyun-3 D star on July 29th, there were two fire spots in Murmansk region in northwest Russia, both located along the Arctic Ocean and in the Arctic Circle. The influence area of the two fires is 4 square kilometers, and the area of naked fire is 0.1 hectares. (Source: National Satellite Meteorological Center)
The warming rate in the northern hemisphere is faster than the global level, and the high temperature and drought make the forest more dry and flammable. Studies have found that forests in the northern hemisphere are burning at a speed that has not been seen in at least nearly 10 thousand years. Wildfires release carbon dioxide into the atmosphere, further aggravating global warming.
Extreme weather is frequent or due to climate warming
Recently, in addition to high temperature, other abnormal weather events have also appeared frequently. For example, at the end of June, snow fell in Newfoundland and parts of Cape Breton in eastern Canada, with a thickness of about two centimeters. The temperature in St. John and Halifax is only MINUS 1℃, breaking the record of low temperature. Such weather is rare, and it is the first time since 1996.
Why does extreme weather ravage the world? The World Meteorological Organization believes that frequent extreme weather is related to climate change caused by greenhouse gas emissions. Although it is difficult to simply attribute the frequent occurrence of extreme weather in the past two months to climate change caused by human activities, in the long run, the trend of extreme high temperature and increasing precipitation is undoubtedly caused by climate change.
"2018 will be one of the hottest years on record, and it is not surprising that temperatures in many countries have broken records. At present, the heat wave and extreme high temperature events we are experiencing are consistent with the results we expected from climate change caused by greenhouse gas emissions. This situation is not going to happen in the future, but a scene that is being experienced at all times. " Elena Monankova, Deputy Secretary-General of the World Meteorological Organization, said.
In northern Siberia, along the coast of the Arctic Ocean, model analysis shows that a high temperature of over 90 degrees Fahrenheit appeared on July 5, 40 degrees Fahrenheit higher than the normal temperature. In Ouargla, Algeria, the temperature reached 124.3 degrees Fahrenheit (51.3 degrees Celsius), breaking the previous African high temperature record of 123.3 degrees Fahrenheit (50.7 degrees Celsius).
