500-mb maps the 500-mb map generally includes the same raw data, contours, and isotherms as the 850-mb map. occasionally, vorticity (a measure of eddies in the general wind flow) is also depicted. maps at this level to show how storms will move, since the speed and direction of 500-mb winds “steer” their paths. 13. what contour interval is used to show heights on the 500-mb map in figure 9-16? 14. what range of heights do you see on the 500-mb map?

i would expect light rain in pittsburgh throughout the following 24 to 48 hours. the lower/falling weights in urban areas toward the west demonstrate that a low weight framework is moving from west to east toward pittsburgh. low weight frameworks are ordinarily connected with precipitation. the way that you don't see a major drop in temperature in the more western urban areas demonstrates the low weight framework is moving with a warm front, so just light rain would be normal. substantial downpours or progressively vicious climate is just typically connected with chilly fronts, where the warm air is pushed up and over a cool front quickly. this quickly rising air (convection) is what gives you heavier torrential downpours, and other conceivably serious weather conditions.
