Score for this quiz: 2.5 out of 2.5 Submitted Feb 9 at 11:24am This attempt took 3 minutes. Question 1 0.25 / 0.25 pts On the map being presented by the sarcastic cartoon weatherman, there are “H’s” and “L’s.” What do these symbols commonly mean in the context of weather maps? Cartoon1.png High/Low precipitation Correct! High/Low pressure High/Low temperature High/Low cloud cover The H’s, which are typically colored blue, and the L’s, which are typically red, are used to represent areas of High and Low pressure. Question 2 0.25 / 0.25 pts The map below shows a weather pattern for the US that is so crazy it is borderline swear-worthy. Using this map, look for the frontal boundary that cuts across the western United States (Northwest to Southeast) What type of frontal boundary is this? Cartoon2.gif Correct! Stationary front Warm front Cold front Occluded front The alternating pattern of red half circles and blue triangles on a weather map are used to represent a stationary front. Please note, this is in contrast to the alternating pattern seen on an occluded front, which has the half circles and triangles pointing in the same direction. Question 3 0.25 / 0.25 pts The “doughnut” shaped weather pattern that Homer is biting into is actually called a “cut-off” low pressure system, which is occurring about half way up in the atmosphere (~18,000ft). The round shape of the weather pattern is created by connecting lines of equal height along a constant pressure surface. Therefore, this entire map has the same pressure (in this case, 500mb), but

consists of different heights above sea level. The lines that connect regions of equal height are called? (Apologies about the resolution. Maps like these are far more readable when Homer isn't added in). Cartoon3.jpg Isobars Correct! Isoheights Isotach Isotherms Lines of equal heights are called isoheights. This type of line is NOT used on the common surface weather chart. Rather, those are lines of equal pressure called isobars. Question 4 0.25 / 0.25 pts This cartoon below shows a frontal boundary. It is symboled with a red line and half circles pointing in the direction the front is moving. What type of front is this? Cartoon4.jpg Cold front Stationary front Correct! Warm front Occluded front A red line with half circles on it is the symbol for warm front. Also, the direction of the half circles indicates the movement of the front’s direction. In this case the front would be moving to the right of the picture. Question 5 0.25 / 0.25 pts This somewhat morbid cartoon shows a tropical cyclone approaching the Philippines, and then shows an injured Island in the aftermath. Consider the location of the Philippines, and determine the proper name for this tropical cyclone. Cartoon5.jpg Correct! Typhoon

Cyclone Hurricane This would be a Typhoon. If a tropical cyclone forms in the Western Pacific Ocean, then it would be called a Typhoon. Hurricanes form in the Eastern Pacific or the North Atlantic. Cyclones form in the South Pacific or the Indian Ocean. Question 6 0.25 / 0.25 pts Look at each of the possible weather forecast for this cartoon city, notice, that one option is “devastating cyclone.” Since there are only certain regions on Earth where a tropical cyclone can be called a “cyclone,” determine the likely location based on the following answer choices. Cartoon6.jpg Correct! New Zealand Japan Cambodia America New Zealand can be the only possible answer. A tropical cyclone that forms in the Indian Ocean or the South Pacific are called Cyclones. If a tropical cyclone is the North Atlantic or the Eastern pacific it is called a Hurricane. If a tropical cyclone is the Western Pacific it is called a Typhoon Question 7 0.25 / 0.25 pts Television weather forecast maps, like the one below, are typically presented with the surface meteorological conditions (Weather maps can be made to show conditions at various heights in the atmosphere, not just the surface). When the map is of the surface, contour lines are drawn across the map. What do these lines typically represent? Cartoon7.jpg Correct! Lines of equal pressure called isobars Lines of equal temperature called isotherms Lines of equal isotach Lines of equal precipitation called isohyet Isobars is the correct answer. Almost always, surface weather maps show the lines of equal pressure.
