- A tug of war between wind shear and buoyancy (instability)
- W951499S
- This close-up of W951500Z depicts a tug of war between two principles of physics- vertical wind shear and buoyancy (instability). An approaching short wave trough is cooling the atmosphere aloft, increasing instability and promoting rapid vertical development in these clouds. But countering this trend is wind shear because the clouds tower into much stronger winds up there which tilts the clouds far forward, ripping the tops off. Will growth outpace shear to form a storm? The possibility of storms depends on the right balance between these two opposing forces.
