If not for the Earth's rotation, global winds would blow in straight north-south lines. ... The Coriolis effect influences wind direction around the world in this way: in the Northern Hemisphere it curves winds to the right; in the Southern Hemisphere it curves them left. The exception is with low pressure systems.
Isobars and isotherms are both lines on weather maps that represent patterns of pressure and temperature. They show how temperature and pressure are changing over space. They describe the large-scale weather patterns across a region in the map.
