Trade winds

The Earth is on an axis allowing only 50% of sunlight to reach the Earth. The equator receives the most sunlight throughout the year. While the north and south receive different amounts of sunlight during the year. The global wind patterns all depends on the way the Earth moves. The Earth moves to the right so the wind patterns move to the left in a circular rotation.   The Earth moves to the right while the air and water move to the left. The activity that we had done in class poking a small hole in the middle of the round paper circle and spinning it to the right on a thin strong metal tool. While dropping little drops of water on to it shows that the water moves to the left. Even though the paper circle was spinning to the right. Coriolis means a effect mass moving in the rotating system experiences a force and Hadley cells means large scale cell in which air rises at the equator. With the way the Earth is on its axis there is more sunlight found at 30 degrees north and south latitude.The wind patterns all go in a circular motion starting from the left. The trade winds, doldrums, horse latitudes, and westerlies. The global wind patterns activity that we had done in class was if someone spins a beach ball globe and a dry erase marker. Put the marker at the top at the globe and try to draw a straight line to the left all the way to the bottom of the globe,while another person is spinning the globe to the right. It is shorter to go from New York to California than it is to go to California to New York. The westerlies go into a circle with the trade winds.
Due to global warming, the winds with shift more towards the equator.
