Hey guys, I have this huge assignment due tomorrow. I've done everything except two questions that are listed below. If someone can solve these for me, I would be grateful; in fact, I am even willing to pay 10 dollars to that person. I have another essay to write, so I can't do it on my own right now. I'd really appreciate it. thanks


--------

DALR=10°C/Km (dry adiabatic lapse rate)
MADR=6°C/Km(moist adiabatic lapse rate)
DWLR=2°C/Km (Dew point lapse rate)

1. The surface of the earth has a temperature of 21°C and a dew point of 10°C. The environmental lapse rate is 4°C/Km. A balloon is then warmed to a temperature of 30°C. The balloon is then forced to rise in the atmosphere, first to 1000 m, than 2000 m, 3000 m and finally 4000 m.
i. Calculate the temperature inside the balloon at each level (assume no exchange of heat with the environment).
ii. At the height (if any) will condensation form inside the balloon?
iii. What is the stability of the balloon at each level?
iv. Where (if anywhere) is the level of neutral stability?

2. At the base of a 4000 m mountain in the BC cascade Mountains (on the windward side), the air temperature is 4°C and the dew point is -24°C. On the leeward side there is an extensive plain 1000 m above the base of the mountain. Air flows from the windward to the leeward side of the mountain.
i. What is the temperature of the air and the dew point on the plain? What indication do you have that the air is drier on the plain? Explain where the moisture went.
ii. What kind of precipitation is falling at the top of the mountain? Indicate the cloud level on both sides of the mountain.
iii. If the dew point at the base of the mountain on the windward side was -20°C rather than -24°C, at what height would clouds form? How would this change the temperature at the top of the mountain? On the plain?
iv. What height would the plain have to be in order for it to have the same temperature as the air at the base on the wind ward side?
