Parameter Selections...

• QG versus SG/PBL (theory/application)
• Sensible weather versus field plots
• Interpretation of data products
• Opinions versus needs, level of trust
• How to display physical accuracy
• How best to visualize/interpret with minimal
  mis-interpretation/application and useful
• Human Factors (HF)...

9
Model Comparisons...

• Emphasis on visual context and ability to
  physically represent processes
• Time/Space accuracy and function of synoptic
  and/or mesoscale setting

• Not algorithm check
• Not new parameterizations
• Not strictly for one location
• Gain in use and understanding of meso-scale model
  output

The BasicsForecast Funnel

• Standard Level Plots for 925, 850, 700, 500, 300,
  and 200mb levels inclusive of wind direction and
  speed, heights, and temperature in time lapse
  (hourly) and for static times (0000 and 1200 UTC)
• Basic analyses for above standard plots including
  thermal and moisture advection, moisture
  convergence and Q-vectors, cloud water and
  precipitation type, vertical velocities,
  vorticity, vorticity advection, net vertical
  vorticity advection, potential vorticity, jets,
  thickness, thickness advection, net vertical
  displacement, precipitable water, and 12-hour
  change of parameters
• Surface Plots of sea level pressure, wind speed
  and direction, accumulated precipitation,
  dewpoint in time lapse (hourly) and for static
  times (0000 and 1200 UTC)

12
Basicsand a finer scale

• Skew-T diagrams, hodographs, and meteograms in
  time lapse (hourly) and for static times (0000
  and 1200 UTC) and vertical plots in
  three-dimensional perspective in time lapse for
  regional evolution
• Three-dimensional plots for upper troposphere,
  mid troposphere, and lower troposphere
  illustrating rising and sinking motions, relative
  humidities, mixing ratios, and cross-sections in
  time lapse (hourly) and for static times (0000
  and 1200 UTC)
• Frontogenesis, theta-e, vertical wind shear,
  parcel trajectory/path motion, Richardson
  number, wet-bulb zero, lid strength, potential
  temperature, isentropic analysis, sensible
  weather at surface, skin temperature, soil
  moisture, mixing heights, refractive index,
  scattering, insolation, gravity waves, sea/land
