At sea level, an air parcel at 20°C has a relative humidity of 50%. As the unsaturated air parcel rises 1 kin up a mountain, the air cools to a temperature of 10QC and becomes completely saturated. The air parcel continues to climb to the top of the mountain—an elevation of 2 km. What were the air’s capacity and the humidity at sea level? What was the dew point temperature at an elevation of 1 km? What was the air temperature at the top of the mountain (elevation 2 km)?

On a summer day in Houston, the temperature is 35 C and the realative humidity is 77 percent
A) What is the humidity?
B) To what temperature could the air be cooled before condensation starts to take place? (That is, what is the dew point?)
Explain how hail forms? You need to understand that the middle part of a cumulonimbus cloud, where the air temperature is between -40° C and 0° C, there exists a combination of ice and supercooled liquid water droplets, which are cloud droplets that remain liquid even though the temperature is below the normal freezing point of liquid water. This should be part of your explanation. How large can hail get? Why are strong updrafts necessary to produce extremely large hail?
An Associated Press article on climate change said, “Some of the ice shelf’s disappearance was probably during times when the planet was 36 degrees Fahrenheit (2 degrees Celsius) to 37 degrees Fahrenheit (3 degrees Celsius)warmer than it is today.” What mistake did the reporter make?
