A Gantt chart is a type of bar chart that illustrates a project schedule. [citation needed] This chart lists the tasks to be performed on the vertical axis, and time intervals on the horizontal axis. The width of the horizontal bars in the graph show the duration of each activity.
Trade Winds. In the Northern Hemisphere, warm air around the equator rises and flows north toward the pole. As the air moves away from the equator, the Coriolis effect deflects it toward the right. It cools and descends near 30 degrees North latitude. The descending air blows from the northeast to the southwest, back toward the equator (Ross, 1995). A similar wind pattern occurs in the Southern Hemisphere; these winds blow from the southeast toward the northwest and descend near 30 degrees South latitude.
This of course isn't to be confused with the kind of wind that causes people to have to hold their noses in crowded classrooms. No, this kind of wind is a flow of the air across parts of the earth. Winds can be global or local. Global winds travel large distances and fall into general patterns. Trade winds tend to flow diagonally toward the equator, easterlies go west, and westerlies go east. But in today's lesson, we're talking about local winds. Local winds are on a much smaller, nearby scale. Your particular home city might have winds that tend to come from the east during one season and the west during another. Or, it might be totally different. The pattern of typical winds you get in a local area is what we call a local wind. Usually they're on the scale of tens of miles to hundreds of miles. These winds can be cold or hot, dry or wet. They can be mild and safe or violent and dangerous. Local winds have a big affect on the weather conditions.
