What is the formula for CCL

• 400 x (Surface temp - Dew point)

• 400 x (surface temp - Dew point) x 0.85

• 400 x (Dew point - surface temp) x 0.85

• 400 x (Dew point - surface temp)

LCL is always higher than CCL

• True

• False

LCL is a measure of air that is

• Forced to rise orographically and forms cloud

• cooled adiabatically and forms cloud

• cooled through widespread ascent and forms cloud where the dew point meets the temperature

• completely unstable

How does the DALR change with height?

• It steepens

• It shallows off

• It does not change

• It will initially steepen and then start to shallow towards the upper layers of the troposphere

How does the SALR change with height?

• It will steepen

• It will shallow off

• It will stay the same

• It steepens initially and then shallows off towards the tropopause

At sea level the temperature is 20 Degrees C. At 5000ft cloud forms. What should the temperature be at 7000ft assuming standard lapse rates?

• 2 degrees

• 18 degrees

• 4 degrees

• 1 degree

The temperature at sea level is 17 degrees C. The dew point is 11 degrees. The ELR is 4 degrees C. Where will cloud form and what type of weather will be associated with the cloud? Assume RCL conditions.

• 2000ft. Light rain and light turbulence

• 1500ft. Showers and potential lightning activity

• 2000ft. Showers and potential lightning activity

• 1500ft. Light rain and light turbulence

A sea breeze:

• comes in around 10am and peaks at 2-4pm

• comes in around 12pm and peaks at 2pm

• comes in just after sunrise and peaks at 2-4pm

• comes in around 10pm and peaks at 2-4am

How strong is a sea breeze and how far inland can it extend?

• 10-15kts and may spread as far as 25-40km inland

• 15-20kts and may extend as far as 60km inland

• 10-15kts and may extend as far as 25km inland

• 5-8kts and may extend as far as 25-40km inland

How may a heat low affect a sea breeze?

• It will act to weaken the sea breeze

• It will act to strengthen the sea breeze

• It will cause the winds to blow at oblique angles to the shoreline

• It may cause a reversal of the flow where by a sea breeze is reversed into a land breeze
