Question

Choose the statements that describe what occurs when an air parcel reaches the Lifting Condensation Level (LCL) and is ready to produce clouds. The parcel’s relative humidity increases to 100%. The parcel’s temperature decreases to the dew point. The parcel becomes saturated. The parcel's rate of evaporation exceeds the rate of condensation. The parcel is compressed and cools.

Answer 1

Answer:

Option (1)

Explanation:

The Lifting Condensation Level (LCL) refers to that pressure level at which a parcel of air becomes saturated thereby lifting the air parcel from any distinct pressure level. As the air rises up, it cools and the relative humidity starts increasing in that air parcel, which then reaches 100% and this is the point at which the LCL occurs. This also helps in the determination of the reasonable cloud base height.

Thus, the correct answer is option (1).
