It is not quite doing that, but moving at an angle with respect to the isobars, so that it appears to be spiraling around and into the low. But for that principle to exactly work, the air would be moving at right angles to the isobars. It generally matches what you'd expect from that principle. Explain if your streamline pattern generally matches this rule, substantiating it.(15 points) (b) A general principle in meteorology is that in the absence of other effects, on a given level, like sea level, air tends to move from higher values of pressure to lower values of pressure. It appears that the air is moving across the isobars from higher to lower pressure, but the air is also moving counterclockwise with respect to the center of the low. (a) Formulate a 'rule' relating the streamline pattern to the isobar pattern shown (15 points) Using acetate and the lighttable, as explained in class, transfer your streamline analysis onto this chart. The isobars are labeled in whole millibars with the 10 or 9 dropped off.ģ. The chart below shows the same weather map with an analysis of isobars on it. The pattern that I discern is that the air appears to be blowing counterclockwise, directed towards a common point in southwestern Pennsylvania. (Answer in complete sentences, in this space, or on the back, or on separate sheets) What is the pattern you discern in the streamlines? (10 points) Draw streamlines on this chart (discussed in class). In reality, you'd need to test the hypothesis on many weather maps to 'prove' the stated relationship statistically.ġ. Then you will test the hypothesis on a different weather map. You will then discern patterns in the streamlines.Īnd then you will apply a proven principle on ( on a level surface, in the absence of other effects, air blows directly from areas of higher values of pressure to areas of lower values of pressure) to form a hypothesis. In this lab exercise, you will constsruct streamlines on the basis of weather information (data). Test the Hypothesis: See if the same hypothesized cause is associated with the same effects in other places, or for other times etc.

Make a Hypothesis: Make a first guess about the reasons for the pattern or problem based upon proven principles or understood causes/effects.ģ. Define a Problem: Obtain and/or examine data and discern a pattern ofĢ. Scientific Method - An organized approach utilized to systematically study and solve problems of the natural world.ġ. The first three steps are listed below under the definition. We are discussing the scientific method in lecture.
