|
Definition
|
|
Term
|
Definition
Wave Forms in trade winds (easterly wave) -> Areas of convergence and divergence Air rises in areas of convergence -> Condensation releases latent heat
Heat causes more warming and pressure drop -> More moist air that is brought into the storm -> More condensation |
