Weather maps and computers

Weather maps have isobarsContinuous lines that connect areas with the same air pressure., continuous lines that connect areas with the same air pressure. Meteorologists use isobars to observe the development of high and low pressure areas. A high pressure areaAn area where the air is cooler and more dense, and the air pressure is higher than normal. is surrounded by winds that blow clockwise in the northern hemisphere and counterclockwise in the southern hemisphere. It usually brings dry weather. A low pressure areaAn area where the air is warmer and less dense, and the air pressure is lower than normal. is surrounded by winds that blow counterclockwise in the northern hemisphere and clockwise in the southern...
