Show Stationary Fronts And The Weather How is a stationary front formed? What causes most of them in fall and winter? A STATIONARY front usually results from the movement of a cold air mass into a mass of warmer air. Instead of forcing a passage and breaking through, sometimes some-times the cold front's winds will blow parallel to the juncture junc-ture of the two air masses. THE COLD air mass thus stands still-as far as forward movement is concerned. The warm air mass sends its winds parallel to the juncture line (the stationary front), but in exactly the opposite direction of those of the cold air masses. In summary, the stationary front is set up when a warm and cold air mass meet and neither is 9trong enough to dissipate the other. |
