# Embry Riddle Meteorology Atmospheric Moisture and Clouds Questions

Choose TWO questions – one from each question set – to answer. Place your chosen questions and the formulated answers* within a separate document that includes your name at the top.

Use mainly course resources – textbook readings and module lesson content – to develop your answers, vs. doing an internet search. Regardless of the source, provide references for the information used in formulating your answers.

*Your answers will be scored on completeness, correctness, clarity, and conciseness, and the degree of synthesis and application of the related concepts, not on how many words they contain. More is not necessarily better!

#### Question Set 1: Weather Applications in Everyday Life

1. Describe the season of the year and time of day, along with a qualitative (i.e., with descriptive words, not numerical values) description of the wind speed, temperature, dew point temperature, and relative humidity conditions that would cause your skin to dry the quickest after stepping out of a swimming pool. For these quick-dry conditions, state the specific thermodynamic process causing the drying, and why you will feel cold as the drying takes place. Synthesize and apply related concepts from Modules 2 and 3 to support your answers.
2. On a day in August at Patrick Space Force Base (located along the Atlantic coast in central Florida), after a hard lunchtime workout in the base’s air-conditioned fitness center, you exit the facility with your sunglasses on. Synthesize and apply related concepts from Modules 2 and 3 to explain why the lenses of your sunglasses instantly fog over as you step outside.
3. Suppose it is a Saturday morning, and while watching your local weather forecast on television, you hear the meteorologist state that the predicted maximum heat index for the day will approach 100 °F. Synthesize and apply related concepts from Modules 2 and 3 to explain why this information indicates that engaging in outdoor activities on Saturday afternoon could be potentially dangerous to your health.
4. You are at an outdoor restaurant with friends on a warm, humid evening. Synthesize and apply related concepts from Modules 2 and 3 to explain why, shortly after receiving a round of cold beverages, puddles of water begin forming on the table around the beverage containers.
1. #### Question Set 2: Weather Applications in Aviation

1. Synthesize and apply related concepts from Modules 2 and 3 to explain why, on a given summer day, a regional airfield located near sea level along the central California coastline is more likely to have both smaller changes in temperature over the course of the day, and greater chances for low cloud ceilings and low visibility conditions, compared to a regional airfield located in the lee of California’s Sierra Nevada mountain range at elevation 4500 feet.
2. A general aviation aircraft miraculously lands safely at a regional airport with a cracked windshield and significant damage to the leading edges of the wings. The pilot stated that severe turbulence, strong downdrafts, heavy rain, and low visibility were encountered while passing beneath the base of a large cloud on approach to landing. Synthesizing and applying related concepts from Module 3, a) name the type of cloud the aircraft likely encountered, and b) support your answer for the cloud type by explaining the reasoning behind the aircraft damage and pilot landing experience described in the scenario.
3. Synthesize and apply related concepts from Modules 2 and 3 to explain why using a weather satellite infrared image would be best for determining the presence of fog and/or low clouds at an airfield.
4. Synthesize and apply related concepts from Modules 2 and 3 to a) explain how jet condensation trails form, and b) discuss the factors that affect their duration once formed (i.e., whether they will be short- or long-li
