The plane traveling from New York to Cape Town would be affected by several global winds, including the trade winds, the westerlies, and the South Atlantic High.
The trade winds blow from the northeast in the Northern Hemisphere and from the southeast in the Southern Hemisphere. They are steady, reliable winds that blow towards the equator, and they would help to push the plane towards the south and west as it crosses the Atlantic Ocean.
The westerlies blow from the west in both hemispheres and are responsible for the weather patterns in the mid-latitudes. They can be strong and variable, and they would affect the plane's course as it crosses over South America and the South Atlantic Ocean. The plane would need to navigate around areas of low pressure and strong winds to maintain a steady course.
The South Atlantic High is a semi-permanent high-pressure system that is located over the South Atlantic Ocean. It can affect the plane's flight path by creating areas of calm or strong winds, depending on its location and intensity. The plane would need to monitor the position and strength of the high-pressure system to avoid areas of turbulence or unfavorable winds.
Overall, the plane would need to take into account the complex interactions of these global winds in order to plan its flight path and maintain a safe and efficient journey from New York to Cape Town.
