1 Name: Section: B Lab #3: Atmospheric CirculationThe movement of air in the Earth system - winds! - are controlled by differences in temperature and pressure. In this exercise, we’ll explore the fundamental controls that determine both the vertical and horizontal movement of air in the Earth system. Based on these, at the end of the lab we’ll develop an expectation for what the global pattern of winds should look like based on what we know about energy distribution in the Earth system. Part 1: Vertical Circulation The figure below shows a simple schematic of an enclosed space with a heat source at the lower left and a cooling element at the upper right. 1.A. In the figure below, please draw, or insert shapes, using lines and arrows how you would expect the air to circulate in the box. 1. B. Label by typing in one of the circles in the box below to indicate the area of low pressure in the box with the letter L 1.C Label by typing in one of the circles in the box below to indicate the area of high pressure in the box with the letter H
2 Part 2: Simple Horizontal Circulation The figures below show a simplified diagram as if one were looking down at the surface of the Earth (a map view). A high pressure region at the surface is marked with an H and a low pressure region at the surface is marked with an L. The parallel lines between them are isobars indicating locations of equal pressure.
