1, Explain how and why each of the following will change as a parcel of air with an unchanging amount of water vapor rises (thus both expanding and cooling) in 1-2 sentences : (a) absolute humidity; (b) actual vapor pressure; (c) saturation vapor pressure; (d) relative humidity.
2. The Great Flood of 1862 was the largest flood ever recorded in the U.S. West, likely driven by sequential atmospheric river events that drove heavy precipitation along the windward flank of the Sierra Nevada. A recent study by Swain et al. (2018) noted that the odds of another event similar to the Great Flood was about 50/50 by 2050. Such an event would be exacerbated by climate change, with enhanced rainfall due to higher atmospheric water vapor content.
