This cold front is not very strong because there isn't a tightening of the isotherms. Isotherms are lines of constant or equal temperature They are often used on weather maps by meteorologists to give a large scale view of temperatures across the US If you have ever looked at a weather map in a newspaper, the isotherms are used to divide the color-filled temperatures. Isotherms are lines of equal temperature. 4. We can see the thrust of the cold front is pushing into western Texas after drawing only two isotherms.

The isobar interval is selected so as to provide what is generally the most useful resolution of the field of data; too small an interval (for example, 1 mb) would clutter the map with too many lines and too great an interval (for example, 10 mb) would ordinarily mean too few lines to adequately define the pattern. "Iso" means same, and "therm" can be interpreted as air temperature. Use their previous posi-tions (past history) as a guide. Draw contour lines with interval of 20 feet. Here are some helpful hints: 1. 0000005310 00000 n endobj 2. The name Skew-T stands for skewed temperature since the isotherms at 10 degree intervals are curved or skewed to the.

Reading the 500 mb Height on Maps The contours on the map are actually the altitude of the 500 mb pressure surface in meters above sea level (mb stands for millibars, which is a unit for measuring pressure, just like meters is a unit for measuring distance). National Weather Service Usually, they are connected to a low pressure system, which rotates counterclockwise. Answer 1 of 2. When a cold mass of air is penetrating an area you will see a definitive border between the warmer air and cooler air on an isotherm map. [t48 j@Aqks*00~dX Isotherms are drawn in ten-degree intervals.
