Climate Sensitivity Derived from First-Principles Temperature Feedback Circuits
Ming Cai, Jie Sun, Zhe-Min Tan +3
A long-standing challenge in climate science since the Charney Report in 1979 is to determine how much the Earth's climate warms in response to a unit external energy input at the…
Models of Wildland Fire and Ember Spread
Kevin Speer, Bryan Quaife, Jie Sun
In this Chapter we explore the nature and theory of ember transport using observations from controlled laboratory settings, prescribed fire, and wildland fire. Specific examples an…
Wave Energy Is Conserved in a Spatially Varying and Inhomogeneously Moving Medium
Zhaohua Wu, Jie Sun, Zhe-Min Tan +3
Waves are propagating disturbances that redistribute energy across space. Previous studies have shown that for waves propagating through an inhomogeneously moving mean flow, the co…
The Ceiling Height of Wildland Fire Plumes in Sheared Boundary Layer Flow
Jie Sun, Kevin Speer, Bryan Quaife +2
Radar observations from a prescribed fire experiment reveal a large-scale, billow-like vorticity pair associated with the plume head at the onset of plume bending. The bending conf…
