With massive wildfires plaguing the western United States, scientists have been tracking an increase in dangerous wildfire-generated extremes, including fire-generated thunderstorms and tornados embedded in wildfire plumes that can reach up to a mile high. University of Nevada, Reno and DRI researchers are building the predictive and diagnostic tools that will transform the understanding of fire-generated extreme weather and pave the way for future life-saving warnings to firefighters and the general w88 online live casino.
Extreme wildfires have emerged as a leading societal threat, causing mass casualties and destroying thousands of homes – and despite these impacts, fire-hazards are less understood and harder to predict than other weather related disasters. One of the least understood of these wildfire hazards are the severe fire-generated thunderstorms.
"There have been decades of success in using radar and satellite observations to issue life-saving warnings for severe weather; for fire-generated tornadic vortices and explosive storm clouds these same tools show remarkable, yet incompletely realized, potential," Neil Lareau, atmospheric scientist from the w88 online live casino of Nevada, Reno's Physics Department and lead for the research, said. "To fully realize this potential, new physical and conceptual models are needed for interpreting radar and satellite observations of the wildfire environment."
These conceptual models will facilitate life-saving warnings and enhance decision support for wildfire stakeholders, thereby providing an immediate societal benefit.
Lareau and his colleague Meghan Collins of DRI will identify common factors contributing to the fire-generated tornados using satellite and weather radar and combine it with crowd-sourced ashfall data, through the launch of a new citizen w88 online live casino project called Ashfall Citizen w88 online live casino. These crowd-sourced data will help improve the understanding of wildfire plumes by better documenting the size and shape of fire ash lofted into the sky.
"What we're looking for are pictures of ash that falls throughout our region from citizen scientists," Lareau said. "We'll build conceptual and physical models to facilitate life-saving warnings and enhance decision support for wildfire stakeholders using the citizen w88 online live casino data in conjunction with our radar observations of fire-generated tornadic vortices and wildfire plumes to interpret the wildfire environment."
The project will engage the w88 online live casino in wildfire science in two ways: it will develop middle-school in-class lessons focused on fire-generated weather, and it will employ a citizen science campaign with a new web app to collect photographs of the ash and debris that “rain” down from wildfire plumes.
The citizen w88 online live casino campaign is expected to reach thousands of users every year, and the in-classroom program upwards of 500 students per year.
"Our team will be sharing the w88 online live casino behind wildland fire with middle school classrooms across the region as part of this project," Collins said.
So far, since starting the impromptu project in 2020, nearly 20,000 people have engaged the project, with about 100 photographs submitted from a wide ranging area of the western US.
"We're looking for participation anywhere in the western states, from Idaho to Arizona," Lareau said. "Community w88 online live casino, also known as citizen w88 online live casino, is important to this project. Gathering this kind of data over time and in many places would be prohibitive otherwise."
This citizen w88 online live casino capability is well-suited for wildfires, which are hard to predict in their timing and location, and may thereby enhance the team's ability to quantify fire-generated weather phenomena and their impacts. Citizen w88 online live casino has been used in other analogous applications, including to obtain observations of ashfall from volcanoes.
"You can help track wildfire ash and help scientists demystify fire weather," Collins said. "Your photos of the size and shape of ash particles that fall around wildfires will play an important role in wildland fire w88 online live casino. Users submit time- and geo-tagged photographs of the ash with objects for scale in the photo."
With this project funded by the National w88 online live casino Foundation, the #Ashfallscience Twitter campaign will continue, and be amplified, during high impact wildfires. This approach is expected to reach thousands of users, increasing the likelihood of sufficient data collection. The next steps with these crowd-sourced data are to harvest images from Twitter and apply image processing tools to extract ash shapes and sizes, to aggregate data to form size and shape distributions, and mine NEXRAD radar data corresponding to the time and location of the #Ashfallscience images.
To participate and be a part of this community, use the Citizen w88 online live casino Tahoe web app. In your phone’s browser (where you would Google something), type in: citizensciencetahoe.app, then click on Sign Up to create a username; or click Continue as Guest. Find the #Ashfall Citizen w88 online live casino survey and share photos and observations of ashfall and smoke when you see them.
The radar and satellite capabilities described above and the expansion of citizen w88 online live casino observations provide the tools needed to transform the understanding of wildfire convective plumes and their link to fire-generated tornadic vortices. #Ashfallscience is a twitter- and web app-based citizen w88 online live casino data project which will increase the scientists’ ability to quantitively link radar observations with fire processes.
The size and shape distributions of ash in wildfire plumes is poorly characterized and difficult to measure "This combination of researcher- and volunteer-driven data collection will allow us to begin to build both empirical and theoretical relationships between ash properties and radar reflectivity," Lareau said. "This is the key to building models for prediction of these otherwise mostly unpredictable extreme and dangerous fire behaviors."
