User: She worked really hard on the project. They can be used to find areas of low or high pressure over a broad area (like the U.S.), and they can tell us how intense the system may be. A contour line (also isoline, isopleth, or isarithm) of a function of two variables is a curve along which the function has a constant value, so that the curve joins points of equal value. The H's mark centers of high pressure (highest pressure in the region), while the L's mark centers of low pressure (lowest pressure in the region). Therefore, the temperature at point "P" is less than 10 degrees Fahrenheit but greater than 5 degrees Fahrenheit. Isobar is equal pressure, but isotherm is iso means same and them means tempreature, so its equal temp. Well, generally speaking, areas of high pressure at the surface are often areas of "fair" weather (relatively calm, with at least some sunshine). Consider this contour map of sea-level pressure with a point "P" located in Montana. Each type of isoline is named to reflect the variable being mapped: isotherms are lines of constant temperature; isobars are lines of constant baro-meb-ic pressure; and isodrosothcrms are lines of constant dew point. Meteorologists use isobars on weather maps to depict atmospheric pressure changes over an area and to make predictions concerning wind flow. First, we must identify the two contours that lie on either side of "P." In some cases the contours that we need are clearly labeled; however, in other instances, you will need to use the contour interval (1,000 feet, in this case) to "count" up or down from a labeled contour. answer choices. Instruments covered are isobars, isotherms, satellites, radars, barometers, humidity, relative humidity, sling psychrometer, anemometer, wind vane (sock), and rain gauge. Isotherms are regular in southern hemisphere and irregular manner in northern hemisphere because of preponderance of land in northern hemisphere. The last drawn contour is 13,000 feet.
