Ridges upper level highs
When the height contours bend strongly to the north (as in the diagram below), this is known as a RIDGE. Strong ridges are accompanied by warm and dry weather conditions at the surface.
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.
Ridge (of high pressure) In meteorology, an elongated area of relatively high atmospheric pressure, almost always associated with and most clearly identified as an area of maximum anticyclonic curvature of wind flow.
Ridge
A ridge is an elongated area of high pressure. It is indicated by rounded isobars extending outwards from an anticyclone and has associated with it a ridge line.

Theta-e Ridge - An axis of relatively high values of theta-e. Severe weather and excessive rainfall often occur near or just upstream from a theta-e ridge.
Hostile Ridge This term, used earlier in the week by forecaster Byron Paulson of the National Weather Service Forecast Office in Chanhassen, MN can be safely called a meterological colloquialism.
Ridge: It is an extended area of relatively higher atmospheric pressure. It can be the extension of an anticyclone. It is the opposite of trough and generally is associated with good weather, as the anticyclone itself.
