Why can the leading edge of cool outflow sometimes form a new line of clouds?
Answer and explanation
Correct answer: It lifts the warm, moist air ahead
Rain-cooled downdraft air spreads outward at the ground and forms an advancing gust front or outflow boundary. At that boundary, the denser cool air undercuts the warmer, moist air ahead and forces it upward. Rising air may reach saturation, causing condensation and a new line of cumulus or storm clouds.
