– A line of constant wind speed.

– the line of equal temperature denoted on surface weather maps.

– Inter-tropical Convergence Zone. The region where the northeasterly and southeasterly tradewinds converge, forming an often continuous band of clouds or thunderstorms near the equator.

– A relative maximum of windflow within the jet stream.

– Strong winds concentrated within a narrow band in the atmosphere. The jet stream often “steers” surface features such as fronts and low pressure systems.

– Local winds a result of cold, dense air flowing downhill.
