Local high temperature disaster risk, experts explain in detail the first yellow warning of high temperature this year: "Heat Rise" in Northern Region Inner Mongolia | High Temperature | Northern Region
On June 14th at 18:00, the Central Meteorological Observatory issued the first high temperature yellow warning of the year: It is expected that during the day of June 15th, there will be high temperatures of over 35 ℃ in North China, the Yellow River and Huaihe River, southeastern and western Inner Mongolia, eastern Xinjiang, and southern Xinjiang Basin. Among them, some areas of Beijing Tianjin Hebei, Henan, Shandong, Anhui, Inner Mongolia, Xinjiang and other provinces will have the highest temperature of 37-39 ℃, with local temperatures reaching over 40 ℃.
What are the characteristics of this high-temperature process? Is it extreme?
On June 14th, Zhang Fanghua, the chief forecaster of the Central Weather Bureau, explained to the media that this round of high temperature process will gradually develop from June 13th and is expected to reach its strongest stage from June 15th to 16th. This high-temperature process has the characteristics of wide impact range, fast development, and strong intensity, with a duration of about 3 days. Due to the relatively low relative humidity, the public may still feel dry, hot, and sunny.
The Central Meteorological Observatory predicts that from June 15th to 17th, there will be high temperatures of over 35 ℃ in the eastern part of North China, the Yellow and Huai Rivers, Liaoning, and southeastern Inner Mongolia. Among them, the highest daily temperatures in some areas of Beijing Tianjin Hebei, central and northern Henan, central and western Shandong, northern Anhui, southeastern Inner Mongolia, and western Liaoning will reach 37 ℃ to 39 ℃, with some areas reaching over 40 ℃; After the 18th, the range of high temperature impact will significantly decrease and the intensity will weaken.
Zhang Fanghua introduced that a few days ago, the North China region was located at the rear of the Northeast Cold Vortex, and there were often small weak cold air "sweeping" down, bringing a feeling of "high sky and light clouds" or even "cool breeze". Now, as the Northeast cold vortex moves out of China, the next three days will mainly be affected by warm high-pressure ridges in North China, Yellow River and Huaihe River, and high temperature weather will follow.
Under the control of warm high-pressure ridges, sinking airflow will prevail in the North China Huanghuai region, and there will be less cloud cover in the sky. Due to the combined effects of sinking warming and radiation warming, the temperature will significantly increase. In addition, the relatively low daytime relative humidity in the above-mentioned areas is also conducive to an increase in temperature; In addition, due to the special terrain of North China, the highest temperature in the central part of Hebei Province at the eastern foot of the Taihang Mountains can reach 40 ℃.
Is it extreme? Zhang Fanghua said that it is expected that from June 15 to 16, the impact range and intensity of high temperature in North China, Huang Huai and other places will be the largest. At that time, the highest temperatures in North China, Huanghuai, southeastern Inner Mongolia, Liaoning, and other areas will be significantly higher than the same period in normal years, and some areas will approach the historical extreme values of the same period.
What risks will this round of high temperature process bring? How should we respond? Zhang Fanghua reminds that the northern region is experiencing a significant increase in summer heat, with hot weather. North China, the Yellow River and Huaihe River, as well as Liaoning and Inner Mongolia, are at high risk of high temperature disasters. There is a high demand for electricity and energy, and there is a risk of heatstroke or heat stroke during outdoor activities. Elderly people, children, or those with weaker physical fitness should try to avoid going out during hot periods in the afternoon, while also paying attention to avoiding heat and sun protection, and doing a good job of hydration and cooling.
High temperature weather will lead to an increase in electricity and water consumption. It is recommended to do a good job in scientific scheduling and supply of hydropower and energy. In addition, it is necessary to strengthen urban and forest grassland fire prevention, and do a good job in traffic safety management during hot and hot weather.
In addition, due to the continuous high temperature, winter wheat in Xinjiang is at a high risk of dry and hot winds. Xinjiang also needs to prevent floods in small and medium-sized rivers caused by high temperature snowmelt. According to the monitoring of the Ministry of Water Resources, from 8:00 on June 13th to 8:00 on June 14th, due to the impact of high-temperature snowmelt, floods exceeding the warning flow occurred in the Hash River, a tributary of the Ili River, and the Kezi River, an upstream tributary of the Kashgar River in Xinjiang. It is expected that the high temperature weather in Xinjiang will weaken from the 15th, but the high temperature will develop again from the 18th to the 21st, with local temperatures reaching over 42 ℃. The Kashgar River, Kuobu River, and Kaidu River in the northwest of Xinjiang need to prevent meteorological risks of exceeding the warning water level.
