Isobars

Isobars are described as line on a map that represents different patterns of temperature and pressure. These lines spread across the entire region of the country to help show the differentiation in the pressure gradient and exactly how this affects the overall temperature of that particular area. The point being behind these lines is it makes the general public more catch on easier as to exactly what is happening around the country. If we take a long on a map that has presented to us by the national weather service we can see the change in temperature highlighted by shading in color variation and by the lines stretching across the country from one region to another. In this particular map, we can see the isobars stretching across the country from north to south which exemplifies exactly what we just talked about.
