11. CIN is strengthened by low altitude dry air advection and surface air cooling. 12. On principle, advective terms can be computed using any suitable advection scheme. 13. The positive vorticity advection area is typically associated with divergence and upward motion. 14. The negative vorticity advection area will be associated with convergence and downward motion. 15. It is a method from the texture advection family. 16. During advection , a fluid transports some conserved quantity or material via bulk motion. 17. Advection requires currents in the fluid, and so cannot happen in rigid solids.18. The previous equation is the'advection form'of the Burgers'equation. 19. Similarly, much smaller ratios indicate a higher rate of diffusion relative to advection . 20. The convection term is often written as, where the advection operator is used.
