What does warm ridge mean?

Warm ridge refers to a long and narrow area extending from the high temperature area, which is usually represented as a warm ridge line, that is, starting from the warm center, it is outlined along a series of curvature maxima points of isotherms.

In meteorology, it is usually necessary to analyze the ratio between warm air in the lower troposphere and cold air in the middle and upper troposphere with the help of temperature field, and to analyze the warm ridge in the lower troposphere and the cold trough in the middle troposphere. Warm ridge refers to a long and narrow area extending from high temperature area, which is usually characterized by warm ridge line, that is, starting from the warm center, it is outlined along a series of curvature maxima points of isotherms.

In China, the warm ridge usually extends from south to north, from west to east or from southwest to northeast.

In the analysis and processing of meteorological data in China, manually or with the help of computer software (such as MICAPS-China meteorological information comprehensive analysis and processing system; ) provided by auxiliary tools.

Its drawing quality is inevitably affected by human factors (such as lack of experience). By constructing a reasonable algorithm, the automatic extraction of warm ridge points and the automatic drawing of warm ridge lines are realized, which lays a foundation for automatic analysis and mining more objective weather laws based on weather maps.
