ATMO 203: STUDY GUIDE FOR
TUTORIAL 20
1) Know what horizontal discretization means and two ways this is done in weather models.
2) Know what vertical coordinates are used in weather models and why height and pressure are not used for this purpose.
3) Know the meaning and importance of horizontal and vertical resolution.
4) Know what is meant by the domain, update frequency, and analysis cycle of the model.
5) Know the horizontal
discretization, vertical coordinates, horizontal and vertical resolution,
domain, update frequency and analysis cycle of the major models (
6) Know the difference between FOUS, EXT, and MOS. Know which is most reliable for temperatures and which is most reliable for precipitation.
7) Be able to read the following from FOUS output:
a) Precipitation
b) Humidity
c) Vertical velocity
d) Lifted index
e) Wind speed and direction
f) Thickness
g) Temperature near the surface
8) Be able to read the following from MOS output:
a) Max and min temperature
b) Temperature and dewpoint
c) Cloud cover
d) Wind speed and direction
e) Probability of precipitation
f) Precipitation amount
g) Probability of thunderstorms and severe thunderstorms
h) Ceiling, visibility, and obstructions to visibility
9) Be able to read EXT data, this is probably the easiest of the three to read.
10) Be able to access FOUS, EXT, and MOS data through the weather interface.
