Answer:
Once the external force is removed , the air parcel will remain at that level.
Yes a cloud will form
Explanation:
Given that:
Temperature of the air parcel = 30 ° C
Dew point temperature = 20 ° C
Dry adiabatic lapse rate D = 10° C/Km
Moist adiabatic lapse rate M= 4° C/Km
external force lifting the air parcel from surface to the attitude = 1 km
Let first calculate the air temperature T at the top of the mountain
T =
T = 30 ° C - ( 10 ° C/Km × 1 km ) - ( 4° C/Km × 1 km )
T = 30 ° C - 10 ° C - 4 ° C
T = 30 ° C - 14 ° C
T = 16 ° C
The temperature at the top of the mountain is 16 ° C
What will happen to the air parcel once the external forcing is removed?
Once the external force is removed , the air parcel will remain at that level.
This is because, from the information given: air temperature will drop to .20° C by the dry adiabatic lapse rate of 10° C/km at an altitude of 1 km.
Since both the air parcel temperature and the external temperature are taking place at 1 km ; then no external force is applied thus, they will remain at that level.
Will a cloud form?
Yes, a cloud will form
GIven that ; the Dew point temperature = 20 ° C , the air parcel will no be able to either sink or rise. Therefore condensation of vapor to water will occur which in turns form a cloud.
