Question
1- The boundary of continental polar air moving out of Canada is shown by a blue line with triangles stretching from northeastern U.S. to northern Oklahoma. Given that this cold front is to advance further south, will the temperatures will be cooler or warmer the following day in north-central North Carolina?
2- locate the high pressure over Iowa. Would the pressure increase or decrease as you move outward horizontally for several hundreds of miles.
3-At North Platte, in central Nebraska, the air pressure corrected to sea level was 1030.3 mb and at San Antonio, in south-central Texas, it was 1024.2 mb. Which city of the two mentioned above is experiencing the cooler temperature?
4- By looking at the station models, which city (either North Platte or San Antonio) contains less water vapor? Blank 1
5-dianapolis, in central Indiana had winds from the ______________ at about 5 knots and the air pressure corrected to sea level was __________________ mb.
6-Centered over Western Wyoming is a high pressure system. Winds around this high pressure system are blowing clockwise or counterclockwise? Blank 1
7-In San Diego, California in the southern part of the state, the wind direction is coming from

1. As the cold front progresses towards North Carolina, the temperatures will decrease and hence it will be cooler.
2. As we move out horizontally from Iowa, the pressure will decrease.
3. North Platte, Nebraska will experience cooler temperatures as the pressure is higher than San Antonio, Texas.
4. San Antonio will have more water vapour. This can be attributed to the fact that the difference in temperature and dew point is inversely proportional to the amount of water vapour present.
5. The wind is from North North-West and the pressure is 1027.9 mb
6. The winds from the high pressure system in Northern Hemisphere will always blow clockwise
7. The winds in San Diego are from the North West
