|
|
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 |
|

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
|
|
Term
| what temperature condition is indicated if wet snow is encountered at your flight |
|
Definition
| temperature is above freezing at my altitude |
|
|
Term
| the presence of ice pellets at the surface is evidence that |
