	Ridge - Wikipedia, the free encyclopedia
		Ridges are usually termed hills or mountains as well, depending on size.
		Stratigraphic ridge: In places such as the Ridge-and-valley Appalachians, very long, very even, very straight ridges are formed due to the fact that they're the uneroded remaining edges of the more resistant strata that were folded laterally.
		Volcanic caldera ridges: Large volcanoes often leave collapsed central calderas that are bordered by circular ridges.

	AMS Glossary
		Sometimes, particularly in discussions of atmospheric waves embedded in the westerlies, a ridge line is considered to be a line drawn through all points at which the anticyclonically curved isobars or contour lines are tangent to a latitude circle.
		The most common use of this term is to distinguish it from the closed circulation of a high (or anticyclone); but a ridge may include a high (and an upper-air ridge may be associated with a surface high) and a high may have one or more distinct ridges radiating from its center.
		The opposite of a ridge is a trough.

	Ridge lift: Just the facts... (Site not responding. Last check: 2007-10-10)
		Ridge lift (or 'slope lift') is created when a prevailing wind strikes a geologic obstacle that is large and steep enough to deflect the wind upward.
		If the wind is strong enough and the ridge high enough, it provides enough force for gliders (Aircraft supported only by the dynamic action of air against its surfaces) to stay airborne for long durations or travel great distances.
		Long mountain ranges such as those found in the United States, New Zealand, and Chile have been used by glider pilots to fly in excess of a thousand kilometers in a single flight.

	Sadler, UHMET-75-05
		The easterly currents of the tropical and equatorial region between the subtropical ridges of the two hemispheres or between the subtropical or subequatorial ridge of the summer hemisphere and the buffer system will be referred to as the tropical easterlies.
		The summer hemisphere ridge has a normal poleward movement with the march of the sun; however, in the winter hemisphere the ridge also moves poleward in opposition to the march of the sun.
		The subtropical easterlies, between the subtropical ridge and the TUTT, average 5 to 10 kt and the subtropical westerlies, between the TUTT and the subequatorial ridge, average less than 10 kt.

	References for “The Asian Monsoon” book – Chapter 7
		In a wet monsoon year, the western North Pacific subtropical ridge is stronger as a result of positive feedback that involves the anomalous Hadley and Walker circulations, an atmospheric Rossby wave response to the western Pacific complementary cooling, and the evaporation-wind feedback.
		This ridge extends farther to the west from the previous winter to the following fall, resulting in an 850-hPa anomalous anticyclone near the southeast coast of China.
		The decadal scale variability in ridge position at 500 hPa over India in April at 75 degrees E (an important parameter used for the long-range forecast of monsoon) and NAO is also investigated.

	A LINEAR MODEL STUDY OF THE MID TROPOSPHERIC RIDGE ... A. Chandrasekar and B. N. Goswami (Site not responding. Last check: 2007-10-10)
		A linear model of the steady response of a stratified fluid to isolated heat sources is used to study the maintainence of the mean position of the mid tropospheric ridge and its displacement.
		(1986) have advanced the hypothesis that the location of the mid tropospheric ridge along 75° E is a measure of the influence exerted by the troughs in the Westerlies on the upper tropospheric thermal conditions over North and Central India.
		The latitudinal position of the 500 mb ridge along 75° E in April has been extensively used by most of the long range forecasters to predict the Summer Monsoon rainfall since it has emerged as one of the important predictors (Hasternath and Greischar, 1993).

	Ridges: upper level highs
		Strong ridges are accompanied by warm and dry weather conditions at the surface.
		A ridge is located from Texas into Montana and is indicated by the bulge in the geopotential height field.
		This is the upper level extension of a surface high pressure center, which is why ridges are also called upper level highs.

	Ridge of air made difference this storm season
		In past years, hurricanes slid around the weak side of a ridge of high pressure called the Bermuda High and stayed away from Florida.
		Florida is spared when troughs — or areas of low pressure usually accompanied by storms — move east across the United States and erode the Bermuda High.
		Frances came across at a higher longitude, and the strong ridge kept it on a track toward southeast Florida.
