Occluded fronts have an area of warm air aloft. The air with greater density moves under the less dense warmer air, lifting it, which can cause a line of showers and thunderstorms, or a squall line to form when there is sufficient moisture. var mapping_btmslot_a = googletag.sizeMapping().addSize([746, 0], [[300, 250], 'fluid']).addSize([0, 0], [[300, 250], [320, 50], [300, 50], 'fluid']).build(); There are several factors that influence the final shape and tilt of the circulation around the front, ultimately determining the kind and location of clouds and precipitation. The warmer air interacts with the cooler air mass along the boundary, and usually produces precipitation. { bidder: 'triplelift', params: { inventoryCode: 'Cambridge_MidArticle' }}, Add the power of Cambridge Dictionary to your website using our free search box widgets.
