1qr. Briefly explain the movement of water in the hydrologic cycle. Get solution
1qt. Use the concepts of condensation and saturation to explain why eyeglasses often fog up after coming indoors on a cold day. Get solution
2qr. How does condensation differ from precipitation? Get solution
2qt. After completing a grueling semester of meteorological course work, you call your travel agent to arrange a much-needed summer vacation. When your agent suggests a trip to the desert, you decline because of a concern that the dry air will make your skin feel uncomfortable. The travel agent assures you that almost daily “desert relative humidities are above 90 percent.” Could the agent be correct? Explain. Get solution
3qr. What are condensation nuclei and why are they important in our atmosphere? Get solution
3qt. Can the actual vapor pressure ever be greater than the saturation vapor pressure? Explain. Get solution
4qr. In a volume of air, how does the actual vapor pressure differ from the saturation vapor pressure? When are they the same? Get solution
4qt. Suppose while measuring the relative humidity using a sling psychrometer, you accidentally moisten both the dry-bulb and the wet-bulb thermometers. Will the relative humidity you determine be higher or lower than the air’s true relative humidity? Get solution
5qr. What does saturation vapor pressure primarily depend upon? Get solution
5qt. A large family lives in northern Minnesota. This family gets together for a huge dinner three times a year: on Thanksgiving, on Christmas, and on the March equinox. The Thanksgiving and Christmas dinners consist of turkey, ham, mashed potatoes, and lots of boiled vegetables. The March dinner is pizza. The air temperature inside the home is about the same for all three meals (70°F), yet everyone remarks about how “warm, cozy, and comfortable” the air feels during the Thanksgiving and Christmas dinners, and how “cool” the inside air feels during the equinox meal. Explain to the family members why they might feel “warmer” inside the house during Thanksgiving and Christmas, and “cooler” during the March equinox. (The answer has nothing to do with the amount or type of food consumed.) Get solution
6qr. (a) What does the relative humidity represent? (b) When the relative humidity is given, why is it also important to know the air temperature? (c) Explain two ways the relative humidity may be changed. (d) During what part of the day is the relative humidity normally lowest? Normally highest? Get solution
6qt. Why is advection fog more common along the coast of southern California than along the coast of southern Virginia? Get solution
7qr. Why do hot and humid summer days usually feel hotter than hot and dry summer days? Get solution
7qt. With all other factors being equal, would you expect a lower minimum temperature on a night with cirrus clouds or on a night with stratocumulus clouds? Explain your answer. Get solution
8qr. Why is cold polar air described as “dry” when the relative humidity of that air is very high? Get solution
8qt. Explain why icebergs are frequently surrounded by fog. Get solution
9qr. Why is the wet-bulb temperature a good measure of how cool human skin can become? Get solution
9qt. While driving from cold air (well below freezing) into much warmer air (well above freezing), frost forms on the windshield of the car. Does the frost form on the inside or outside of the windshield? How can the frost form when the air is so warm? Get solution
10qr. (a) What is the dew-point temperature? (b) How is the difference between dew point and air temperature related to the relative humidity? Get solution
10qt. Why do relative humidities seldom reach 100 percent in polluted air? Get solution
11qr. How can you obtain both the dew point and the relative humidity using a sling psychrometer? Get solution
11qt. If all fog droplets gradually settle earthward, explain how fog can last (without disappearing) for many days at a time. Get solution
12qr. Explain how dew, frozen dew, and visible frost form. Get solution
12qt. The air temperature during the night cools to the dew point in a deep layer, producing fog. Before the fog formed, the air temperature cooled each hour about 3°F. After the fog formed, the air temperature cooled by only 1°F each hour. Give two reasons why the air cooled more slowly after the fog formed. Get solution
13qr. List the two primary ways in which fog forms. Get solution
13qt. Why can you see your breath on a cold morning? Does the air temperature have to be below freezing for this to occur? Get solution
14qr. Describe the conditions that are necessary for the formation of: (a) radiation fog (b) advection fog Get solution
14qt. The sky is overcast and it is raining. Explain how you could tell if the cloud above you is a nimbostratus or a cumulonimbus. Get solution
15qr. How does evaporation (mixing) fog form? Get solution
15qt. You are sitting inside your house on a sunny afternoon. The shades are drawn and you look at the window and notice the sun disappears for about 10 seconds. The alternate light and dark period lasts for nearly 30 minutes. Are the clouds passing in front of the sun cirrocumulus, altocumulus, stratocumulus, or cumulus? Give a reasonable explanation for your answer. Get solution
16qr. Clouds are most generally classified by height above the earth’s surface. List the major height categories and the cloud types associated with each. Get solution
17qr. How can you distinguish altostratus clouds from cirrostratus clouds? Get solution
18qr. Which clouds are normally associated with each of the following characteristics: (a) mackerel sky (b) lightning (c) halos (d) hailstones (e) mares’ tails (f) anvil top (g) light continuous rain or snow (h) heavy rain showers Get solution
