Name: ___________________________ MSC 243 Laboratory #2, 6 SEPTEMBER 2011 Due Thursday 8 th September OBJECTIVES To familiarize yourselves with drawing contours on maps. To prepare traditional surface analyses based on surface station models. To identify weather features in these surface analyses. Some helpful illustrations are given on pages 4-5 (Figure 1.6 and 1.9) CONTOURING TECHNIQUES 1. Fig. 1.20 shows the total rainfall in Pennsylvania, in tenths of inches, produced by the remains of Hurricane Agnes in June 1972. Draw isohyets (lines of equal rainfall) of 8 inches and 12 inches to identify the regions that experienced the heaviest rainfall. 2. Fig. 1.21 shows wind speeds (in knots) at 33000 feet altitude, measured by rawinsonde balloons. (a) Draw the 60-, 90- and 120-knot isotachs (lines of equal wind speed), and identify the jet stream. Do this by shading all areas of the map with wind speeds of over 60 kt. (b) Draw a dark line within the shaded area to represent the narrow channel of fastest winds. 3. Fig. 1.22 shows station models in Texas and the surrounding states. Draw isotherms (lines of constant temperature) in multiples of 10. (a) Shade in all areas where temperatures are warmer than 60F, and areas where temperatures are lower than 40F. What is the unshaded region? (b) Using other information in the station models, identify changes in the wind
