• Map of North America with longitude and latitude
• Drawing compass
1. View the map from the lab given. The map represents the barometric pressures at 5000 feet in North America on a precise day in February.
2. Use the Web to get another map of North America that covers the same approximate area shown in the map given in the lab and is noted with latitude and longitude. Keep in mind at mid-latitudes, one degree of latitude is approximately 60 nautical miles.
3. Note that there is a knot is a nautical mile per hour. There are 6076.115 feet in a nautical mile (versus 5280 feet in a statute mile). This means 1 knot is faster by a factor of (6076.115/5280) or 1.15.
4. Use the representation given in lab to fill in the isobars and specify the direction of air movement a high and low-pressure area perceived on the map.

The theory behind the lab is to be able to figure out how areas of low and high pressure were in the southern hemisphere. To understand that wind flows counterclockwise when around the lower pressure and that wind flow clockwise around the high pressure wind. To be able to identify the reaction to differences in pressure. To be capable to spots point of equal pressure called isobars.
b. If I have made any mistakes, then it would have been in the calculations of finding the gradient because I had a hard time on understanding on how properly find the pressure gradient between the two regions. I did the best I could in researching and using the lab information to properly do this. Another mistake that could have possibly been made was a measurement mistake. When I was estimating the wrong latitude and longitude of the pressure gradient
