WX 201 FINAL EXAM REVIEW QUESTIONS
WITH CORRECT ANSWERS 2026
⩥ 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
⩥ Sources of Vertical Motion. Answer: 1. Convergence / divergence
2. Topography
3. Fronts
4. Convection
