3. (5 points total) Use the standard Cartesian coordinate system shown below and on it, insert separate arrows showing (1) a southeast geostrophic wind (blue arrow), (ii) the direction the pressure gradient force is acting (red arrow), and (iii) the direction the Coriolis force is acting (green arrow). Also indicate on the graph where the low pressure (with an "L") and high pressure (with an "H") are relative to the wind. Hint: for (i), the arrow should extend from the center of the coordinate system toward the direction the air is flying towards. Y Ex 4. (8 points total) Use the upper air map at 850 hPa below to answer the following questions: a. (2 points) What do the blue lines on this map indicate? b. (1 point) Within the closed contour over Indiana, would you label a high or a low? c. (2 points) What can you say about the pressure at 1500 m in Indiana compared to surrounding areas? How do you know d. (3 points) Do you think air in the layer is colder along the line labeled 1560 or 1530? Why? 3.
