Document Summary
Subject: weather and storm impacts refer to chapters 5 & 7: be able to draw and explain the development of the major circulation (convection cells) that dominate the surface of earth. What are their wind circulation patterns: tropical storm: hurricane, extratropical storm: northeaster, tornado, wind ciruclation patterns:the coriolis force makes the winds in low-pressure weather systems such as hurricanes rotate (counterclockwise in the northern hemisphere and clockwise in the. Air initially starts to move through the atmosphere under the influence of pressure gradients that push it from high pressure to low pressure areas. As it travels, the coriolis force starts to bend its course. The motion tends toward a state called geostrophic flow, where the pressure gradient force and the coriolis force exactly balance each other. At this point the air parcel is no longer moving from a high-pressure to a low-pressure zone. Instead, it follows a course parallel to the isobars: draw a low-pressure system.
