Unformatted text preview: 46 CHAPTER 1 Laboratory Exercises Dakota, the oldest community in the Dakotas. Pembina, also marked with a red dot, lies at approximately 49.0°N, 97.2°W. b. Estimate the temperature gradient between Brownsville and Pembina on both the mid-winter and mid- summer days. By doing this, you are essentially computing a north-south temperature gradient across the lower 48 states. Express your answer in units of °F per 100 miles. Note that if you measure distance di- rectly from north to south, one degree of latitude equals a distance of approximately 69 miles (111 km). C. Assuming that these days are representative of north-south temperature gradients in winter and summer, during what season is the north-south temperature gradient the largest? In the text, we presented a method for computing a gradient using the difference in a parameter between two given points (in the previous question, for example, the parameter was temperature and the two points were Brownsville and Pembina). This definition can be easily adapted to estimate the gradient at a single point. Brownsville and Pembina)....
