What is the Dry Adiabatic Lapse Rate and the Moist Adiabatic Lapse Rate
100
Fog that has horizontal movement of warm moist air over a cold surface
What is Advection Fog

2 basic categories of clouds
What is stratiform and cumuliform
100
This force always moves from High to Low pressure
What is Pressure Gradient Force
100
Instrument that measures humidity
What is a hygrometer

What kind of stability is required for a thunderstorm?
Unstable
200
This fog forms when light winds push moist air up a hillside or mountainside to a level where the air becomes saturated and condensation occurs. This type of fog usually forms a good distance from the peak of the hill or mountain and covers a large area.
What is upslope fog
200
These clouds are stationary lens-shaped clouds that form at high altitudes, normally in perpendicular alignment to the wind direction. They mainly form when the air is stable.
What are Lenticular Clouds
200
The exact opposite of the wind
What is Frictional Force
200
Rain that freezes on contact
What is freezing rain
300
When you push this, it will rise vertically
What is unstable air
300
It is always found at ground level and usually remains stationary. This type of fog can reduce visibility to near zero at times and make driving very hazardous.
What is Radiation Fog
300
These clouds develop horizontally.
What is Stratiform
300
Pressure Gradient Force + Coriolis = 0
What is Geostrophic Balance
300
A severe snowstorm characterized by strong sustained winds of at least 56 km/h (35 mph) and lasting for a prolonged period of time — typically three hours or more.
What is a blizzard
400
A temperature change with height
What is a lapse rate
400
This fog forms when cold air moves over warm water. When the cool air mixes with the warm moist air over the water, the moist air cools until its humidity reaches 100% and fog forms. This type of fog takes on the appearance of wisps of smoke rising off the surface of the water.
What is Steam Fog
400
This cloud produces unstable severe thunderstorms
What is cumulonimbus
400
NAME THE TWO FORCES: 1. This force turns 90 degrees to the right of wind direction in the Northern Hemisphere. It is zero at the equator. 2. This force is the opposite of the Vertical Pressure Gradient Force.
What is Coriolis Force and Gravitational Force
400
This precipitation is formed in the updraft of a thunderstorm, contained in most thunderstorms, occur during mid-afternoon, and are most common in at different months in different regions of the United States.
What is a hailstorm
500
A parcel is only considered unstable if the parcel reaches it's dew point temperature and condenses.
What is conditionally unstable
500
Fog most common to Boulder. MUST BE ABLE TO TELL ME WHY
What is upslope fog. Air is forced up our mountains creating an upslope fog.
500
This cloud produces precipitation, developing cloud bases between the surface and about 10000 ft (3000 m). This cloud typically forms from altostratus in the middle altitude range then subsides into the low altitude range during precipitation.
What is a nimbostratus cloud?
500
F = U⋅2Ωsinφ
What is Coriolis Force
500
A seasonal reversal of winds, that has a warm and dry winter, rainy and hot summer, and during it precipitates 10-15 inches per day.
