1.
Describe the current temperature, dew-point temperature, wind speed and direction, and dominant air mass in Rapid City, SD. The temperature is 53°F, dew-point temperature is 34, wind speed is roughly 3-8 mph, blowing from the east, and the dominant air mass is cP. 2.
Describe the general location of the cold front and warm front. Identify some states that each front is over.
Warm front- North Dakota, Texas, Nebraska, Kansas, Oklahoma
Cold Front- Idaho, Nebraska Illinois, North Dakota, Kentucky
3.
Where is the central area of low pressure? Which cities are located by it?
The central area of low pressure is located east by Rapid City, SD.
4.
Name a city that the occluded front is over.
Rapid City
5.
Assuming if the cold front moves at 40 kmph, list 2 cities where it will be overhead in 24 hours.
Memphis and Chicago
6.
Compare the temperature, dew-point temperature, and wind speed and direction for Pueblo, CO; Wichita, KS; and Memphis, TN. Which cities are experiencing a cT air mass? A mT air mass?
The cities that have a cT air mass would be Wichita, KS and Memphis, TN. The cities that have a mT air mass would be Pueblo, CO.
7.
The precipitation in Colorado occurred after the passage of the cold front. Given that information, which lifting mechanism or mechanisms probably produced the precipitation there? Explain. There is an orographic lifting due to the mountains in Colorado. 8.
The midlatitude cyclone did not pass over southern Florida. Which lifting mechanism was most probably responsible for the precipitation recorded there? Explain.
There is convectional lifting due to Florida being a warmer climate. 9.
Assume that the storm moves due east over the next several days. What would the temperature, dew-point temperature, wind speed and direction, and dominant air mass in Chicago, IL, be after the warm front passes through? After the cold front?
The temperature would be close to 60s with dew-point being mid 50s. The wind speed would be around 3-8 mph moving east. Dominant air mass would be mT. 10. How does the amount of rain recorded across Texas, Oklahoma, Missouri, Iowa, and Illinois compare with the amount of rain recorded across Wisconsin, Michigan, Ontario, and Quebec? Which type of front produced the heaviest rain? The lightest rain? Relate your answer to the properties of warm and cold fronts.
The front that produced the heavier rain was the cold front. The front that produced the lightest rain was the warm front. This could have been from the colder air meeting the warmer air and causes storms.
