How Antarctica Affects the Earth's Climate
Antarctica has a major affect on the Earth's
climate. Since most of Antarctica is covered with a thick sheet of
ice, the winds around that area push the weather opposing the side of the Earth's rotation, causing that climate to slowly move from one place to the other. As the weather move, it gets warmer, but only a little, the climate can travel all the way to the North Pole!!! Look at the pictures below.
So you can see how Antarctica's cold fronts and warm fronts travel around the world. Another factor of how Antarctica affects the weather of the world is; ocean currents. Antarctica has ocans that lead to other lands and make them colder than they already are. This is because the ocean is obviously made out of water, and water transmit heat and coolness to the area around it. You can go to the website below for more information.
Let's focus on cold fronts for a moment. Cold fronts are technically air patterns that transmit climate from one area to another. If a cold front came from Antarctica and went up to the equator, it can make the weather of that area cooler. You can look at the diagram below.
If you look at the diagram to the left, you can see how cold climate can travel to warmer climates to make replace the warm fronts with cold fronts. Cold fronts are always more powerful than warm fronts, so they overpower them. You can watch the video below to understand my point better.
