What are the 5 types of FOG?
- Radiation Fog- caused by the radiation of the earths heat at night .
- Advection Fog- when warm air flows over colder surface.
- Upslope Fog- caused by warm air being forced up a slope
- Steam Fog - ice fog caused when cold air flows over warmer water
- Precipitation Induced Fog - fog caused by rain falling

What is a stationary front?
When two airmasses meet and cannot move one another
What is an occluded from?
When a cold front typically takes over a warm front it causes an inclusion
What is a dry line?
When warm moist air needs warm dry air the only difference between the two airmasses is the level of moisture and dew point
