# Differences Between Wind Patterns And The Northern And Southern Hemispheres

755 Words Apr 2nd, 2016 4 Pages
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 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.
Data:
Map from lap showing wind pressure and knots.

Map showing latitude and longitude for calculations. Calculations: From Nova Scotia to Tennessee which was an estimated point of the middle of the US high pressure area. Given that highest pressure on the map was below 1028 millibars and the lowest was 996. To get the pressure gradient I got the difference between the two millibars (1028-996=32). Once I got that using google I found the distance between the two points which was the…

All these studies have found re-emergence in the extratropical ocean basins. It is observed that re-emergence does not occur in the strong current regions 8,17. Further, these studies regarding re-emergence were confined to individual ocean basins. The identified areas of re-emergence are located in the mode water…

winter warming pattern of surface air temperatures over the Northern Hemisphere continents was noted (Wolfe 2000). The stratospheric heating and tropospheric summer cooling are directly caused by aerosol radiative effects, but the winter warming is indirect, produced by dynamical responses to the enhanced stratospheric latitudinal temperature gradient (Kirchner 1999). As such, the circulation in winter is stronger due to the aerosol radiative effect. The cooling in the Northern Hemisphere is stronger…
