Often recognized as a "Ridge of High Pressure". A ridge is an area of generally high atmospheric pressure. Ridges occur at all levels in the atmosphere. Upper level ridges represent fair weather. Upper level ridges are also favorable environments in the tropics for tropical storms to grow due to less amounts of shear.
An elevated area of the sea floor in the center of an ocean basin with rugged topography, a central rift-valley and recurring seismic activity. Ridges generally stand about 1000 meters to 3000 meters above the adjacent ocean floor and are about 1500 kilometers in width.
A relatively narrow elevation which is prominent because of the steep angle at which it rises; an elongated crest, or series of crests, with or without individual peaks, significantly higher than the adjoining ground.
A ridge (of high pressure), also termed a wedge, is and extension of an anticyclone of high-pressure area shown on a weather chart, corresponding with a ridge running out from the side of a mountain. It is the converse of a trough of low pressure and is generally associated with fine anticyclonic-type weather.
Landform. A long narrow upper section or crest; a long narrow chain of hills or mountains. An area of high ground separating two canyon formed by erosion on both sides. Ridges range in size from those between small gullies to the crest of an entire mountain range. Also called ridgeline.
Capping on topmost part of the roof: a/ Plain - Finished flush to the surface of the roof with minimal decoration. b/ Decorated - Crossed or herring bone pattern pieces c/ Straight Cut Block ridge 3" - 4" (100 - 200 mm) thick cut straight line below bottom ligger. d/ Ornamental Cut Block Bottom edge of the ridge cut shaped to the desired pattern. Ridge Yealm A yealm of ridging material without pronounced taper at either end forming the topmost part of the ridge. Covering of supple straw or sedge grass, laid along apex of roof to bind and protect the main thatch. Other types include wrap-over, butt up, knuckle, rope, flush, straight cut and patterned. Patterns include dragons' teeth, diamond, scalloped, clubbed, herring-bone and crossed
