According to the latest news from the Central Meteorological Observatory, in the next three days, the forest fire risk level will be high in southern Sichuan, central Yunnan and western Yunnan. Although winter is the dry season in the southwest region, forest fires generally occur in the spring from February to May. Why is the current high forest fire risk meteorological level in the southwest region?

Yang Xiaodan, a senior researcher at the Public Meteorological Service Center of the China Meteorological Administration (hereinafter referred to as the "Public Service Center"), said that the meteorological levels of forest fire hazards in some areas of the southwest continue to be higher to higher, mainly because most of the southwest regions have less precipitation and high temperatures since last winter. Since the beginning of winter last year, western Sichuan and most areas of Tibet have been higher than 2℃, with precipitation being less than 50% to 80%, and central Tibet having less than 80%.

As for the high meteorological level of forest fire hazards in central Tibet, Yang Xiaodan analyzed that according to statistics, since the beginning of winter last year, there has been almost no obvious precipitation in Shigatse and Shannan in Tibet, resulting in a low water content of combustible substances in the forest and strong flammability. Once there is a fire source, forest fires are likely to occur. At the same time, since the beginning of winter, strong winds in Shigatse, Shannan and other places have been significantly more than 6 days longer than in previous years, which is very likely to cause the spread of fire sources and have a significant impact on fire fighting.

The meteorological department predicts that there will be a rain and snowy weather process in western Sichuan and eastern Tibet in the near future, which will play a certain role in alleviating local meteorological drought and reducing forest fire risk meteorological levels.

In addition, it is expected that in mid-February (February 10-20), there will be less precipitation in most parts of North China, western Huanghuai, southwestern South China, southern Sichuan, Yunnan and other places; from the 11th to the 12th, 14th to the 15th, and from the 18th to the 20th, affected by cold air, there will be northerly winds of level 4 to 6 in central and eastern my country. The forest fire risk meteorological levels in some areas of Beijing, Hebei, Shanxi, Shandong, Fujian, Guangdong, Guangxi, Sichuan, Yunnan, Tibet and other places are relatively high, and the forest fire risk meteorological levels continue to be high in southwestern Sichuan, central and northern Yunnan, southern Guangdong, and southeastern Guangxi. The fire hazard level of grasslands in western Sichuan is relatively high.

In response to many forest fires in the southwest region and key forest fire prevention areas in the southern region, the China Meteorological Administration organized artificial rain-increasing operations on aircraft and ground, which played a positive role in alleviating local drought and reducing the meteorological level of forest and grassland fire hazards.

In response to forest fire fighting work in Jilong County, Shigatse City, Chayu County, Linzhi City, Luozha County, Shannan City and Yajiang County, Ganzi Tibetan Autonomous Prefecture, Sichuan Province, the Public Meteorological Service Center continues to strengthen consultations with relevant departments of the Ministry of Emergency Management to promptly communicate changes in the fire situation and meteorological service needs, and jointly produce a special report on fire meteorological support for fire emergency fire fighting.

Yang Xiaodan reminds that after spring enters, spring plowing and planting are coming, and there are more situations such as wild outings and agricultural use, and the hidden dangers of fire sources increase accordingly, which can easily cause forest fires. Relevant departments should strengthen inspections in key areas and surrounding areas such as forest areas, power transmission and distribution facilities, construction activities, and timely clean up combustible materials with insufficient safety distances in power transmission and distribution lines, and prevent major forest and grassland fires. The public should continue to improve their fire prevention awareness, not carry fire into the mountains, do not use fire in the wild in violation of regulations, and jointly build a solid forest fire barrier.
