1What is the parallel movement of air mass?
Wind
2What is the vertical movement of air mass?
Convectie current
3What is an isobar?
Equal pressure lines shown on a map relating to weather
4What is a low level wind shear?
Drastic change in wind speed and or direction over a very small area
5What altitude do wind shears occur?
any altitude but dangerous when low
6What are microbursts?
Very intense crazy storm
7What is dew point?
The temperature at which air must be chilled to be saturated
8What does close temperature and dew point cause?
visable moisture (dew, fog, rain clouds)
9When does frost occur?
When the dew point is below freezing and the temperature of the collecting surface is at or below freezing
10What is fog?
A cloud on the surface
11What are the four types of fog?
Radiation
Advection
Upslope
Steam
12When does radation fog happen?
When a warm air mass is caught in a cool ground valley with little to no wind
13When does advection fog happen?
Typically in costal areas, warm and moist air mass pushed in land from the sea breeze, the surface in land is colder where it cools the air mass to become fully saturaterd
14When does upslope fog happen?
When a warm airmass moves up the slope of a mountain and becomes fully saturated from cooling from increase altitutde
15When does steam fog happen?
When a COLD and DRY airmass that moves over a warm and moist area, warm water will steam up and create humidity, happens over warm water usually
16How do clouds form?
Adequete water vapor and a method for air to be cooled
17Clouds are determined by what?
Height
Shape
Characteristics

Associated with mountain flying
Sign of turbulanece
may contain wind 50 knots or more
19What does "nimbus" mean when pertaining to cloud names?
Rain cloud
20What clouds have the greatest turbulence?

21The amount of water vapor which air can hold depends on the...
Air temperature
22What cloud types would indicate convective turbulence?
