Which type of forecast is impacted the most by the butterfly effect? isotherm, line drawn on a map or chart joining points with the same temperature. We often use isolines (lines of con-stant value) for this purpose. They show how temperature and pressure are changing over space and so help describe the large-scale weather patterns across a region in the map. c. Symbols for fronts Well, generally speaking, areas of high pressure at the surface are often areas of "fair" weather (relatively calm, with at least some sunshine). The term "isobar" originates from the Greek, isos (equal) and baros (weight). it locates and tracks storms, and follows the path of storm systems. Think you understand how to extract information from contour maps? When the isobars form a closed loop, a cell is created, with the air flowing in a clockwise direction in high pressure cells (H) and an anticlockwise direction in low pressure cells (L). Isotherms and isobars allow us to view large scale processes much more easily than looking at the raw data from individual weather stations itself. There are no comments.
