Lab 1 - map analysis analyze the attached msl chart by drawing msl 1. pressure isobars every 4 mb. (12 pts) 2. sketch in the direction of the geostrophic wind (use blue arrows) and the surface wind (green arrows) at several locations (minimum 15 for each) on the map. (6 pis) analyze 500 mb height (solid, black) and 500 mb temperatures (dashed, red) on the plotted 500 mb map draw contours at every 6 dm at 558, 564, 570. 576, 582 and 588 dm. (12 pts) 3. 4. if 4 mb isobars are 250 km apart at 45 n, compute the geostrophic wind speed (showing work.) (5 ps) 5. do the same calculation for 30°n (showing work) (5 pts)
