美国国家海洋和大气管理局 (诺阿) released a video on Twitter last week showing the West Coast of the United States. 在视频中, several plumes of smoke from the massive wildfires are clearly visible.
在 a separate post, the NOAA noted that the red marks were an overlay of fire temperature visualization: Only the smoke can be seen from space, but the smoke has blanketed most of the United States in “a hazy pall.”
更多 镜头 from satellites released by a UCLA environmental professor shows the actively burning fires and billowing smoke in alarming clarity.
“NorCal fire situation escalated this PM to level many of us feared it would this season, given extreme drought & record-dry vegetation, with multiple towns impacted by fast-moving fire fronts in past several hours,” Daniel Swain, climate scientist with the UCLA Institute of the Environment and Sustainability, 在推特上写道.
California’s largest wildfire continued to grow Wednesday as thousands of firefighters prepared for a tougher fight due to the return of dangerous weather.
A red flag warning was issued through Thursday because of hot, bone-dry conditions with winds up to 40 英里每小时. That could drive flames through timber, brush and grass, especially along the northern and northeastern sides of the vast Dixie Fire.
“I think we definitely have a few hard days ahead of us,” said Shannon Prather with the U.S. Forest Service.
Heat from the flames created a pyrocumulus cloud, a massive column of smoke that rose 30,000 脚 (10,000 码) in the air, said Mike Wink, a state fire operations section chief.
多于 20,000 firefighters and support personnel were battling 97 大, active wildfires covering 2,919 平方英里 (7,560 平方公里) 在 13 我们. 状态, the National Interagency Fire Center said.
