QUESTIONS WITH VERIFIED SOLUTIONS
RESOURCE

●● Forecast Chart
Answer: Computer model charts predicting future conditions of the
atmosphere; surface charts and upper level charts are created


●● Constant altitude charts
Answer: All locations at the same altitude above ground level (for
surface analysis, pressures are typically adjusted to MSL)


●● Constant pressure charts
Answer: all locations on the chart have the same pressure; contour lines
of equal height of the atmospheric column to that pressure level;
typically used for elevated levels of the atmosphere such as 700 and 500
mb


●● How are surface analyses created?
Answer: -NOA/NWS is the primary source of data in the U.S
-Identify: lows, highs, thoughts, ridges, fronts and station model symbols


●● Isobaric charts

, Answer: -Acquired through radiosondes, satellite, and aircraft


●● Upper Air Station Model
Answer: Temperature, wind, dew point, height


●● Standard Pressure Levels
Answer: 1013mb- 0 ft
850mb- 5,000 ft
700mb- 10,000 ft
500mb- 18,000 ft
300mb- 30,000 ft
250mb- 39,000 ft


●● Location of jet streams
Answer: -Bands of strong wind at tropopause level
-Clear air turbulence
- lead to development and movement of cyclones


●● Vertical Motion
Answer: -Rising motion = air expands and cools = clouds and
precipitation may form if the air is sufficiently humid
-Sinking motion = air is compressed and warms= clearing skies
