Document Summary
Earth has an eccentric orbit and rotation = daily, annually, over 1000s of years" variations in the amt. of insolation. Radiation coming in shortwave, going back out in longwave. Recirculation of energy by atmosphere (the way the energy moves around means we get places that are wet and humid all the time, dry all the time, etc. ) Water had recirculation and buffers the heat. Air moves into the low pressure system on land, sucking in the high pressure fro the water body, creating a cycle. Shifts (energy) up and down in a seasonal, relatively predictable way bet. In asia, a high pressure system is caused by inking cold air, bocking high anticyclone. In july, this changed to a low pressure dominating in the m. east. El nino, a transition bet. sea and atmosphere. N: consider the reasonable handle we have of atmospheric circulation. We"ve been measuring and following its movements for years.
