The extent of circulation induced by Coastal Convergence depends on the general stability of the lower troposphere. In stable conditions the circulation is restricted to the lowest kilometre of the atmosphere, whereas in unstable conditions Coastal Convergence can be conducive to deep convection.

• Divergence:
  Low-level Convergence along or parallel to coast, typically maximum below 2 km altitude. Divergence above.
• Vertical motion:
  Enhanced ascent along or parallel to coast.
