(a)
The height of the LCL if the air parcel has a temperature of
(a)
Answer to Problem 2PA
The height of the Lifting Condensation Level (LCL) is
Explanation of Solution
The height of an air parcel at which the condensation begins is termed as Lifting Condensation Level (LCL). The formula to determine the LCL is as follows:
Substituting the values of Celsius temperature as
To identify the temperature of air parcel at
Given info:
The temperature of the air parcel =
The height of the Lifting Condensation Level (LCL)
To identify the distance between the starting point and the point of condensation, subtract the point of condensation with the starting point.
Substituting the values
Now, divide
Now, subtract the starting temperature (
Therefore, the temperature at the point of condensation is
Now, to determine the distance between the highest point (
Now, divide
Now, to identify the temperature of air parcel at 4000 meters,
Substituting the value
Therefore, the temperature of air parcel that is at
(b)
The calculation of temperature and dew point temperature of an air parcel that has descended to 2,000 meters, which was previously at 6,000 meters having a temperature of –5°C and a dew point of –10°C.
(b)
Answer to Problem 2PA
The temperature of the descending air parcel is
Explanation of Solution
Given info:
The temperature of air parcel at 2000meters = ?
The general rule is that the temperature increases by
Height of air parcel (in meters) | Temperature (celsius) | Dew point temperature (celsius) |
Therefore, the temperature of the descending air parcel is
