|
Definition
abrupt change in temperature lapse rate |
|
|
Term
A characteristic of the atmosphere is |
|
Definition
relatively small changes in temperature with an increase in altitude |
|
|
Term
A jet stream is defined as a wind of |
|
Definition
|
|
Term
the strength of the jet stream is normally |
|
Definition
weaker and farther north in the summer |
|
|
Term
the primary cause of all changes in the Earth's weather is |
|
Definition
variation of solar energy received by the Earth's regions |
|
|
Term
How much colder than standard temperature is the forcast temperature at 9000 ft. as indicated in the following excerpt from the winds and temperature aloft forecast |
|
Definition
2 degrees per 100 feet., 2*9000 = 18 degrees . 15-18= -3 degrees 10-3 degrees = degrees |
|
|
Term
If the air temperature is -8 degrees celcious at an elevation of 1350 ft. a standard temperature lapse rate exdists, what will be will be the appx. freezing level |
|
Definition
|
|
Term
A common type of ground or surface based temperature inversion is that which is produced by |
|
Definition
ground radiation on cool clear nights when the wind is cool |
|
|
Term
the most frequent type of ground or surface based temperature inversion is that produced by |
|
Definition
radiation on a clear, relatively still night |
|
|
Term
what feature is associated with a temperature inversion |
|
Definition
|
|
Term
a temperature inversion will normally form only |
|
Definition
|
|
Term
which weather conditions should be experted beneath a low-level temperature inversion layer when the relative humidity is high |
|
Definition
smooth air and poor visibility due to fog, haze or low clouds |
|
|
Term
winds at 500 ft. agl on a particular flight are southwesterly while most of the surface wind are southeasterly. This difference is primarily due to |
|
Definition
friction between the wind and the surface |
|
|
Term
what relationship exists between the winds at 200 feet above the surface and the surface winds |
|
Definition
the winds at 200 feet tend to paralle the isobars while the surface winds are weaker sue to friction |
|
|
Term
which force, in the northern hemisphere, acts at a right angle to the wind and deflects it to the right until parallel to the isobars |
|
Definition

|
Term
to which meteorological condition does the term "dew point" refer? |
|
Definition
the temperature to which air must be cooled to become saturated |
|
|
Term
the amount of water vapor the air can hold largely depends on |

|
|
Term
what enhances the growth of rate of precipitation? |

|
Definition
temperature is above freezing at my altitude |
|
|
Term
the presence of ice pellets at the surface is evidence that |
|
Definition
there is freeing rain at a higher altitude |
