File:The air over Los Angeles.ogg
Summary
This movie is a combined visualization of the PBL and wind dynamics over the LA basin for a one month period. Vertical motion of the Earth's Planetary Boundary Layer (PBL) - the lowest part of the <a href="//commons.wikimedia.org/wiki/Atmosphere" title="Atmosphere">atmosphere</a> that hugs the surface of the <a href="//commons.wikimedia.org/wiki/Earth" title="Earth">Earth</a> - is represented by the gray "blanket". The height of the PBL is largely driven by convection associated with the changing surface temperature of the Earth (for example, rising during the <a href="//commons.wikimedia.org/wiki/Day" title="Day">day</a> and sinking at <a href="//commons.wikimedia.org/wiki/Night" class="mw-redirect" title="Night">night</a>). The colored arrows represent the strength and direction of winds at different altitudes.
