Question
B) Relati parcel of air which varies vapor pressure) relative to the amount of water that parcel of air can hold (saturated vapor pressure), th temperature (A). Relative humidity (RH) can be calculated directly from; ve and Absolute Humidity: Remember that relative humidity can be described as the amount of water in a RH =×100 where e, - vapor pressure of air (mb) and e, saturated vapor pressure (mb), Note that the same equation can be rearranged so that: RH 100 e,x100 RH and Complete the empty boxes in the table below. Use the graph in A to determine e, and the existing data and equations above to calculatee, or RH. Once completed, answer the questions below. Location Antarctic ice-sheet San Francisco in summer Phoenix AR in summer Amazon Basin | Tar (°C) | e' (mb) | e, (mb) | RH (%) -25 16 32 32 0.5 100 12.5 38.9 Which location's air mass can hold the least amount of water vapor? contains the most water vapor? idiy Why is there so much more available moisture (e) at the Amazon site than the Arizona site? Provided a lifting mechanism exists at both locations, which location would more likely produce clouds on this day Phoenix AR or Amazon Basin? Are any of the locations above experiencing saturation? If so, which one(s) and why do you think?Explanation / Answer
The maximum amount of water vapor that can be in the air depends on the air temperature. Warmer air can hold more water vapor within it.Antarctic ice sheet can hold least amount of vapour pressure.
ii)pheonix AR in summer contains most water vapour.
iii)Antarctic ice sheet has lowest relative humidity.
b)The amazon is warmer and wetter than Phoenix. therefore the vapor pressure is higher in the amazon than in Phoenix and also the amazon is tropical region with lots of precipation with less seasonal rain variation and phoenix arizona has inland area
c)due to the stronger onvection more clouds are in the Amazon as the air will be more likely to reach the lifting condensation level in the Amazon than in arizona .
d) yes San fransisco in summer is experiencing saturation in summer because its relative humidity is 100% andsaturation occurs when the humidity is 100%.
