Contour line positioned at a contour line (when they are, this indicates a measurement precisely equal to the value of the contour). Instead, lines are drawn to best approximate the locations of exact values, based on the scattered information points available. Meteorological contour maps may present collected data such as actual air pressure at a given time, or generalized data such as average pressure over a period of time, or forecast data such as predicted air pressure at some point in the future Thermodynamic diagrams use multiple overlapping contour sets (including isobars and isotherms) to present a picture of the major thermodynamic
Pressure point Pressure point A pressure point (Chinese: ; Japanese: "" "vital point, tender spot"; Sinhala: "Nila/Marma Sthana" (in Angampora); Telugu: "Marma Sthanam"; Malayalam: "marmam"; Tamil: "varmam") derives from the meridian points in Traditional Chinese Medicine and Indian Ayurveda and Siddha medicine, and the field of martial arts, and refers to an area on the human body that may produce significant pain or other effects when manipulated in a specific manner. The concept of pressure points spread through the Tamil martial art called Varma kalai, which is a martial art that concentrates on the body's pressure points. The concept of pressure points
