Explain why large bodies of water such as Lake Michigan can be quite chilly in early July despite the outdoor air temperatures being near or above 90°F (32°C).
3. The dry adiabatic lapse rate, I'd≈1 K/100 m, and the moist (or saturated) adiabatic lapse
rate, I'm depends on moisture content, but is approximated by I'm ≈ 0.5 K/100 m in the
lower troposphere.
(a) If a parcel has 50% relative humidity, what rate will it cool as it rises?
(b) If a parcel has 100% relative humidity, what rate will it cool as it rises?
I'm?
(c) Why is I'd
3. Complete the temperature of an air parcel as it ascends and descents as given below. Assume the
temperature at Okm altitude (sea level on windward side is 6°C; the condensation level of the air
parcel is at 400m (0.4km); dry adiabatic lapse rate of 10°C/km, wet or saturated adiabatic lapse rate
is 6°C/km.
