The first line of defense of disaster prevention and disaster prevention -Deputy Director of China Meteorological Administration Yu Yong interpreted the weather during the flood period

In June, my country entered the main flood season. What is the overall weather situation this year? Which regions have many rainfall? What meteorological services did the meteorological department do ... Yu Yong, deputy director of the China Meteorological Administration, recently accepted an exclusive interview with Xinhuanet reporters to interpret the weather during the flood period.

Since the flood in the flood in my country

"According to the analysis and judgment of the materials of relevant departments, my country has entered the flood season on March 17 this year." Yu Yong said that since the flooding, precipitation has been the distribution characteristics of "South Duo and Northern", and the precipitation of the Pearl River Basin breaks the history of the same period.

According to the statistics of the China Meteorological Administration, since March 17, there have been 18 regional storms in my country since March 17, of which 17 times have occurred in the south and 10 times in the south since May. The national average precipitation was 241.5 mm, which was 11.2%more than the same period of the same year. It was the largest in history since 2017 and the fourth since 1961.

Among them, during the "Dragon Boat Water" from May 21 to June 21, most of Guangdong, most of Guangxi, and the central and eastern parts of Hainan Island generally had a total of 200 ~ 500 mm, and 600 ~ 1000 mm in some areas, of which Guangdong Lianlian Damai Mountain Town in Nanxian reached 1689.2 mm; the average rainfall of Guangdong, Guangxi and Hainan was 472.5 mm, which was the most historical since 2009.

June to August is the main flood season in the traditional sense of our country. Since June, the average nationwide precipitation was 90.7 mm, which was 9.3%more than the same period of the same year. The distribution of precipitation space was unevenly distributed. Essence

Yu Yong said that "strong weather on the weather and the influence of local disasters" is one of the overall characteristics of my country's weather since the flood. He told reporters that since the flood in the flood, there have been 19 strong convective weather process in my country. More than 470 counties (autonomous regions, municipalities) have been affected by hail, thunderstorms, and strong winds, including Guizhou, Shaanxi, Hebei, Yunnan Disaster losses in some areas of the province are heavier.

Different from the south, it has encountered regional and phased meteorological droughts and high temperature weather since the flood in northern my country.

Data show that since late February, meteorological droughts in northern China, northern Central China, southern North China, and east of Northwest China have developed stage. Since June 26, there have been obvious precipitation in the northern dry area, and the drought drought in the dry area has been significantly relieved. At present, there are moderate and above meteorological droughts in the above -mentioned areas. Among them, central Henan, central Hubei, central Jiangsu, southern Gansu and other places have heavy droughts, local special droughts, and the drought -drought and above meteorological drought area is 857,000 square kilometers.

In terms of high temperature weather, since June 13, my country has emerged for the first regional high -temperature weather this year, covering an area of ​​3.696 million square kilometers, affecting the population of more than 600 million people. On the 24th of Henan Province, there were 66 national meteorological stations on the highest temperature or more than 40 ° C, and the Jiaozuo reached 43.3 ° C on the 24th; 90 national meteorological stations in Hebei Province reached or exceeded 40 ° C, of ​​which 12 stations reached or exceeded more than exceeding At 43 ° C, Hebei Lingshou reached 44.2 ° C.

In the next two months, my country's climate condition deviation

"It is expected that from July to August this year, my country's climate is deviated, the staged drought and flood disasters are obvious, the extreme weather and climate events are too large, and the climate change in the season is large." Yu Yong told reporters.

He suggested that he pays attention to meteorological disasters such as heavy rainfall, typhoons, high temperature, meteorological drought, and strong convection, as well as secondary disasters such as floods, mudslides, and urban waterlogging.

According to reports, the main rain areas are located in the southeast, northern, northwest, northern China, northern China, most South China, most Southwest, and southern Tibet. Xinjiang, the west of the northwest region, central and southern East China, central and central China, and other places have less precipitation, and phase meteorological drought may occur. Xinjiang, East China, and the medium high temperature daily are more than the same period of the same year, and a phased high -temperature heat wave will occur. It is expected that the number of typhoons generated in the Northwest Pacific and the South China Sea is expected to be 7-9, which is less than the number of typhoons in my country. It is mainly in the northwest behavior, and the possibility of landing on the typhoon on the north.

According to Yu Yong's analysis, since the spring of this year, due to the influence of the East Middle East Pacific La Nina incident, the outbreak time of the South China Sea Summer and the start time of my country's main rainy season is relatively earlier than usual.

However, in addition to the Lamina incident, the abnormal climate in my country is also affected by other factors such as sea temperatures in other sea areas, as well as other factors such as snow and polar ice. Roll up the positive climate prediction opinion.

Meteorological department multiple measures provides weather forecast and early warning services

"Although the weather forecast cannot be 100%accurate, meteorological workers must use 100%efforts to do a good job." Yu Yong said that in response to the complicated weather situation this year, the China Meteorological Administration did it a month in advance in the flood season in the previous year. Work arrangements for meteorological services.

At the beginning of March this year, the China Meteorological Administration organized a mobilization meeting of the national flood season meteorological service to conduct a comprehensive deployment of meteorological services during the flood season. Since the flood in the flood, the Meteorological Service Leading Group Meeting, Meteorological Services Research Conference, Full System Video Conference will be held to deploy and implement key flood prevention and disaster reduction work.

"Especially for major weather processes, the China Meteorological Administration actively provides good meteorological services in accordance with the principle of" one process, one strategy "." Yu Yong introduced that the Central Meteorological Observatory has strengthened business linkage and warning. The warning of high temperatures was 262 times, and the meteorological departments at all levels issued more than 126,000 various types of early warning information, with a total of more than 821 million people. At the same time, it also pushes the warning information of meteorological disasters accurately for cross -regional agricultural machinery hands and "express brothers".

In addition, the China Meteorological Administration has also strengthened departmental linkage to enhance meteorological disaster prevention and mitigation.

The Central Meteorological Observatory strengthened the Federation of the Federation of Defense, the Ministry of Emergency Management, the Ministry of Water Resources, the Ministry of Natural Resources, and the Ministry of Agriculture and Rural Affairs. Since this year Mountain floods and geological disaster weather risk early warnings of more than 100 periods.

The China Meteorological Administration and Emergency Management Department jointly issued the "Opinions on Strengthening Meteorological Earness and Emergency response linkage" to strengthen the emergency linkage work of high -level meteorological early warning; jointly conduct a provincial -level severe weather monitoring and early warning services with high -level high -level weather.

Yu Yong said that in the next step, the China Meteorological Administration will continue to strengthen the monitoring and early warning of disaster weather, and cooperate with relevant departments to do a good job of rolling conferences and judgment, timely release meteorological forecasting early warning information, give full play to the first line of defense of meteorological disaster prevention and mitigation and mitigation and mitigation. effect.
