Met - Cloud Formation Flashcards
Cumuliform clouds are ….. than the environment
warmer
What 3 places does convergence take place …..
- The equatorial trough
- It occurs in lows
- Happens in the sub polar low
Cumuliform clouds are most likely to develop when …..
there is latitude heating of fast moving cold moist air
Describe how frontal uplift produces clouds ……
- When cold air meets warm air the colder air remains at the surface
- Since the cold air pushes the warm air up this creates clouds
* The boundary between the 2 layers is known as the front
Describe how turbulence in the lower levels can produce clouds …..
Turbulence in the lower levels caused by surface friction can produce clouds at the top of the layer of turbulence.
Sc often forms at the top of this layer
which type of cloud is associated with low ceilings and reduced vis …..
NS
Define convection …..
Clouds form if the ELR allows warm air to rise until the dew point temp is reached
What 3 things cause stratiform clouds …..
- Convergence
- Orographic uplift
- Frontal uplift
What are the 6 ways that clouds form …..
- Convection
- Orographic Uplift
- Frontal Uplift
- Convergence
- Turbulence
- Latitude Heating
If humid air is forced to rise over a mountain range it expands and cools as it rises forming clouds. This is known as …..
Orographic uplift
When 2 air streams meet at the surface what happens …..
they are pushed up and clouds are produced as a result of convergence
What type of cloud formation is never formed by convection ……
Stratiform clouds are never formed by convection
Which cloud type is turbulence in the surface layer most likely to produce …..
SC
What is the most common way for cumuliform clouds to form …..
rising air being cooled by expansion
The most likely cause of turbulence on a hot day is …..
thermal activity
