To see the similarities and differences between wind patterns in the Northern and Southern Hemispheres alongside with explaining the major wind belts.
Material:
• Map of North America with longitude and latitude
• Drawing compass
Procedure:
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

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

I met the purpose of this by observing the wind patterns in the Northern and Southern hemisphere. I described based off the pressures if it was clockwise or counterclockwise. If I could modify and make this lab work better. It would because I would explain the flags on the map given in the lab a little better. That way I have a greater knowledge in what the purpose of the flags are. The diagrams would be different from the lab if they were the Southern hemisphere by being completely opposite from what they are now. There is 6 major winds belts 3 in the Northern Hemisphere and the remaining 3 in the Southern hemisphere. The Tradewinds these winds blow from the Northern East to the Southern East. The Prevailing Westerlies these winds blow in the intermediate latitude. The Polar Easterlies these wind belts blow from the East in the Polar
