东北内蒙古大兴安岭森林再次燃起熊熊大火,引起国人的广泛关注。7月28日,林区工作人员从卫星云图上观测并经地面核实后,发现大兴安岭原始森林发生火灾。着火范围在北纬51-52.3度之间的乌玛、阿龙山、奇乾地区。经分析,雷击是引发火灾的主因。这些地区去年以来天气干旱少雨,过熟林干枯的树枝、站杆倒木多,可燃物多,雷击后易引发火灾。 入夏以来,我国内蒙古北部林区天气持续高温干旱,7月21日至8月7日;降水总量仅为13毫米,比历年同期减少八成。平均气温比历年同期增高2摄氏度,最高气温突破历年同期极高值,干雷暴活动异常活跃,7月28日相继发现多起雷击火点并
The forest in the Greater Xing’an Mountains in northeast China once again raged a blaze of fire, arousing widespread public concern. July 28, forest staff observed from the satellite cloud map and verified by the ground, found in the Greater Xing’an Mountains virgin forest fire. Range of fire between 51-52.3 degrees north latitude Wuma, A Longshan, odd dry areas. After analysis, lightning is the main cause of fire. In these areas, the weather has been dry and dry since last year. The dry branches and overcast poles in the areas of the stands have more fuel and more flammable materials. These areas are prone to cause fire after lightning strikes. Since the beginning of summer, the weather in the northern part of Inner Mongolia of our country has been hot and dry, July 21 to August 7; the total precipitation is only 13 mm, 80% less than the same period of previous years. The average temperature was 2 degrees Celsius higher than that of the same period of previous years. The maximum temperature exceeded the peak value over the same period in previous years. The thunderstorm activity was extremely active. On July 28, more and more lightning fire spots were discovered
