Laboratory 4: Satellite Analysis Techniques--Wave Cyclones (100 pts)

A. General

The analysis techniques center on identifying and locating features associated with the three dimensional aspects of wave cyclones based upon an examination of cloud features. The particular schematic example shown is of a wave cyclone "family"* consisting of two wave cyclones, both at the same stage of occlusion. In reality, wave cyclone families often consist of three or more cyclones, with the eastern one "most' occluded, and the western one an early or incipient wave.

For the surface analysis techniques, the analyst will be able to locate or identify

For the mid and upper tropospheric techniques, the analyst will be able to locte or identify

These techniques are implict on the diagrams, which will be discussed in class.

B. Assignment (Due April 29, 2013)

Print two copies each of the following images:

  1. On one copy of each, find surface lows/highs, locate fronts/triple points, as summarized on this schematic. (50 pts)
  2. On the second copy of each, find major 500 mb troughs/ridges, closed centers, jet streams, as summarized on this schematic. (50 pts)

Obviously, you will be adjusting positions of features because the position of triple point affects your estimate of location of jet streams, as does your estimate of frontal locations, and, to some extent, vice versa. THEREFORE, IT IS IMPORTANT TO DO MULTIPLE ROUGH DRAFTS USING ACETATES.
