Pre-season climate and weather variables indicate a moderate to high chance of a near average wildfire season in Washington and an above average season for Oregon. During this webinar, we’ll explore the factors that make up this outlook, define what a normal fire season looks…

The terrestrial biosphere currently absorbs about 30% of anthropogenic CO2 emissions. This carbon uptake over land results primarily from vegetation’s response to increasing atmospheric CO2 but other factors also play a role. Here we show that since the 1930s increasing…

The paper reports visualization of the flow of smoke over a flat surface inside of a low-speed wind tunnel. A heating plate flush mounted on the wind tunnel floor simulated a spreading line fire that produces uniform heat flux under constant wind speed condition. A paper-thin…

The requirement to model wind is inherently connected with the modelling of many fire-related phenomena. With its defining influence on fire behaviour, spread and smoke transport, the solution of a problem with and without wind exposure will lead to substantially different…

The energy flow from a wildland fire is the most important measurable physical quantity. If we understand the time history of the energy flows, we can derive all other fire behavior and fire effects parameters. Dr. Bob Kremens will describe the difficulties in measuring the…

Intense heating by wildfires can generate deep, smoke-infused thunderstorms, known as pyrocumulonimbus (pyroCb), which can release a large quantity of smoke particles above jet aircraft cruising altitudes. Injections of pyroCb smoke into the lower stratosphere have gained…
