Final answer:
The expected temperature at the LCL is determined using the adiabatic lapse rate.
Step-by-step explanation:
The LCL, or Lifted Condensation Level, is the height at which a parcel of saturated air lifted from the surface becomes saturated and condensation begins to occur. The expected temperature at the LCL can be determined using the adiabatic lapse rate.
The adiabatic lapse rate is the rate at which the temperature of an air parcel changes as it rises or sinks in the atmosphere. The adiabatic lapse rate is usually around 6.5 degrees Celsius per kilometer.
To find the expected temperature at the LCL, you would need to know the initial temperature at the surface, the dew point temperature, and the height of the LCL above the surface.
