Question
1. Which 2 air masses most commonly affect the weather in Ohio?
2. Why is a mid-latitude location, like Ohio, not a good place for forming air masses?
Match each air mass with its description. (mT, mP, cT, cP, and cA Each option will be used once.
3. ________ Common behind a cold fronts that pass through Ohio
4. ________ Only invades Ohio on the coldest days of the year
5. ________ Forms over warm, tropical waters, like the Gulf of Mexico
6. ________ Associated with high temperatures and low humidity, rarely affects Ohio
7. ________ A cool, moist air mass that is more likely to affect Maine than Ohio
8. ________ Which of the following is an example of a process involving air mass modification?
A. cA air mass B. clouds
C. cold front D. lake effect snow
9. Is it a cold front or warm front that is most closely associated with the following progression of cloud types: Ci, Cs, As, St, Ns? Which would be seen first as the front approaches, Ci or Ns?
13. ________ Compare an “average” cold front to an “average” warm front:
A. Generally, cold fronts move faster than warm fronts.
B. Generally, cold fronts have steeper slopes and, therefore, more convection.
C. Generally, cumuliform clouds are more often associated with cold fronts.
D. All of the above are true.
10. Consider the following forecast. “Sunny this morning with increasing clouds as the day progresses. High of 27. Northeasterly winds at 5-10 mph. Cloudy tonight with snow after midnight, possibly mixed with sleet after 3 a.m., and changing to freezing rain by 4 a.m. Accumulation of up to 0.25 inches of ice is possible. Temperatures nearly steady, then slowly rising to about 30. Low of 27. Winds easterly at 5-10 mph. Tomorrow: Cloudy. Rain likely before noon with freezing rain before 7 a.m. Winds shifting toward the south at 10-20 mph. High of 34.”
A weather front moved through the region during the early morning hours. Consider which day is warmer (yesterday or today). Also consider the wind directions and how they change over time. Using the changes in temperature and wind as well as the types of precipitation, is the front that passed through a warm front or a cold front? Explain how you made this decision.
12. Consider the following forecast: “Sunny this morning with increasing clouds as the day progresses. 40% chance of showers and thunderstorms this evening. High of 65. South wind at 5-10 mph this morning, becoming southwesterly and increasing to 10-20 mph. Cloudy tonight with rain and scattered thunderstorms before 2 a.m. Rain may be heavy at times. Low of 47. Gusty southwest winds will shift toward the northwest & subside to 5-10 mph. Tomorrow: Mostly sunny in the morning, partly sunny in the afternoon. High of 53. Winds northwest at 5-15 mph.”This forecast is most likely associated with the passing of which of the following fronts?
As in question 11, a weather front moved through the area overnight. Was it a cold front or a warm front? Describe the clues you used to make your decision.
Explanation / Answer
Answer : 1. maritime tropical (mT) and continental polar (cP). During the summer, the maritime tropical air mass typically brings warm and humid weather, while the continental polar air mass produces cold winter temperatures.
Answer 2 , The region is geographically cut from the warm water sources.So very little atmospheric moisture is available for any air mass forming over an area.
3. Cp
4 . Ca
5. mt
6. mp.
7. ct
