There, the sun is at a very high angle overhead year-round, allowing it to heat the air intensely. This warm air can absorb a lot of moisture and rises. As a result, clouds form in the sky and a low-pressure area develops at ground level. At high altitudes, the air flows towards the poles, either the North or South Pole. These air currents are called antitrade winds. On their way to the poles, the air masses cool down and sink to the ground in the subtropics. This creates high-pressure areas near the ground. To equalize the pressure, air flows from these areas to the low-pressure area near the equator—these air movements are called trade winds. They blow steadily from the northeast and southeast toward the equator, where they form the Intertropical Convergence Zone (ITCZ). Over the course of a year, the ITCZ ​​shifts between the Tropic of Cancer and the Tropic of Capricorn with the sun's position. How does the trade wind circulation develop? The sun is crucial for the development of the trade wind circulation. Over the equator, it is almost directly overhead all year round. This allows it to heat the air near the ground particularly intensely. Because warm air expands, it rises, creating a low-pressure area at ground level. Because the low-pressure area stretches along the equator, it's also called the Equatorial Trough. Shifting of the Intertropical Convergence Zone (ITCZ) Over the course of a year, the sun isn't always directly overhead at the equator, i.e., at its zenith. Because the Earth has a tilted axis and also rotates around the sun, the area where the sun is at its zenith shifts. This occurs within a year between the tropics. With this shift in the sun's position, the location of the ITCZ ​​also changes. It always shifts to where the sun is currently at its highest point. This also shifts the region where the trade winds occur. In summer, they are located so far north that they influence the climate in Southern Europe, for example. --------------------------------------------------------------------------------------------------------------------------- You can find more information on Instagram and TikTok:   / studyflix_app     / studyflix   or on our website: https://studyflix.de/ Here's the link to the free Studyflix app: Play Store: https://play.google.com/store/apps/de...
