Global patterns may last for ten years like the periods in the ice ages ,or repeat each year like the monsoon. There are many different Global climate patterns that come in the form of a cycle as well. Cycles can also be Global climate patterns if they recur. A normal cycle ,which includes the seasonal cycles and Global climate oscillation this is a recurring cycle that happens globally or regionally,for an example El Niño Is also a Global.
El Niño and La Nina is a event that occurs 2-8 years. These two cycles affect the whole global climate but mostly the Pacific and the coast along it. During the El Niño years the trade winds sweeping from the west to the east break down or weaken this is called Southern Oscillation. El Niño causes large amounts of precipitation in the east of the Pacific Ocean, along California and, the parts of mexico and …show more content…
Earth surface being unsymmetrical can change things like atmospheric and oceanographic circulation.The shape of earth surface can also affect the patterns of the wind and ocean. a major geological factor of earth that can affect global climate change would be the movement of the tectonic plates. An example of this would be 40 million years ago when india collided with asia it formed the himalayas. When these mountain ranges obstructed things like equatorial winds and ocean currents. and were major contribute in monsoon seasons of southern Asia and the Indian Ocean, and the El Niño Southern Oscillation in the Pacific
