Multithreaded Advection Calculations

Multithreaded program to simulate the movement of a cloud of material in the atmospheric boundary layer

The wind in the Atmospheric Boundary Layer can be approximated as a horizontal velocity which depends only on height (z) and zero vertical velocity. The horizontal velocity as a function of height vx(z) can be represented by a logarithmic profile

Capture

where u* is a parameter called the “friction velocity”, z0 is a parameter called the “roughness length”, and  = 0.41 is a constant called Von Karman’s constant.
